Your Smartphone Has Been Hacked If You Notice These Signs
Your smartphone is your constant companion. It’s your source of information, entertainment, and social interaction, all in one small device. Most people check their phones at least 20 times a day, which makes them an attractive target for hackers and cybercriminals.
However, security features on most smartphones have made it pretty tricky for hackers to break through and take control of the device without you knowing about it. That doesn’t mean you can let your guard down or give hackers any opportunity to breach your phone’s security measures.
It will help if you remain diligent in keeping from being hacked. If you see any signs indicating that you have been hacked, take action quickly before it has a chance to do further damage to your data and access more personal information.
What causes this to happen in the first place?
To hack into your phone, a person doesn’t necessarily need to be a hacker. While you’re sleeping, someone may bring your phone up to your face and unlock it. With only this one action, they can look through your smartphone secretly.
There is also software that accomplishes the task. Stalkerware is intended to follow you using your location, call logs, messages, photos, browsing history, and other methods. Behind another app that appears to be unimportant, this malware may be disguised.
Your phone may become infected by malicious links and files without your knowledge. Even seemingly innocent PDF files can contain dangerous information. Because of this, it’s crucial to click with caution.
How about apps? Unreliable downloads may mimic well-known applications or attempt to con you into downloading and using them. When you do this, malware is installed on your phone.
There is also a much more focused technique known as SIM swapping. The criminal disconnects your previous connection and transfers everything to the criminal’s device by calling your phone company, pretending to be you, and asking for a new SIM card.
How can you tell if your phone has been compromised? Here are some warning signs:
Your phone is being slowed down by too many processes operating at once, or it can just be malware using up many resources as the sole offender. Your phone may become heated as a result of this.
Your battery is depleting significantly more quickly than usual.
Significant increases in data usage may be a symptom of malware like adware that operates covertly.
Spammy pop-ups clearly indicate that a malicious program has been installed on your phone.
Malware can cause your internet to slow down by diverting your traffic to risky servers or simply using up all of your capacity to steal more data from you or target other people.
Off your phone, there may be some indications, such as emails you don’t recall sending or odd social media posts.
Avoid clicking on shady or uninvited links. This includes emails, internet adverts, and messages from friends.
Keep in mind that your home or business network is neither secure. For advice on how to secure it to keep snoops and bad guys out, tap or click here.
Conclusion
Take action right away if you discover any of these indicators that you’ve been hacked so the hacker can’t access more of your data or cause more damage. Your first step should be to power off your device and change your passwords, especially for social media accounts. Next, report the breach to your phone carrier and contact customer support to see what they can do to help. Finally, clean up your phone and make sure to keep your device protected in the future to avoid being hacked in the future.

Suffolk County Real Estate Industry Crushed by Cyberattack
Following a cyberattack on the Suffolk County government earlier this month, real estate transactions have come to a halt.
Since the cyberattack more than 20 days ago, verifying property titles and filing paperwork has been challenging, which has abruptly halted all deals in the county, according to The Real Deal. On September 8, The Suffolk Times reported that a breach by a group known as BlackCat knocked down county websites, servers, and databases.
It’s been stressful for real estate professionals in the New York area. While this may seem like just another insignificant cybersecurity issue, the implications are much deeper than we can see. In this post, we’ll dive into what happened, why it’s so concerning, and how to stay safe.
What Happened?
The Suffolk county cyber attack crippled the county clerk’s office, which is in charge of documenting paperwork and assisting with records searches for properties, and shut down the county’s internet systems last month.
Due to title companies’ inability to accurately scan county databases to confirm that the properties don’t have any liens, judgments, or other encumbrances to pass title, real estate closings have been postponed or canceled, especially on larger commercial acquisitions.
According to attorney David Rosenberg of Garden City-based Rosenberg Fortuna & Laitman, “After the Suffolk county hack, delay in restoring access to the county’s real estate records, which had been available online before the hack, is causing many title companies to withhold final clearance that would allow closings to occur.”
The ability to ascertain whether new liens, encumbrances, or property transfers have been recorded between the first title report and the closing depends on these documents. In more recent deals, it causes the title company to postpone the initial title report, which makes it impossible for lawyers, purchasers, borrowers, and lenders to close any sizeable transactions confidently.
According to The Suffolk Times, a hacker collective known as BlackCat took responsibility for the suffolk county data breach and demanded payment to allow users back into government servers. The hackers say they have taken four gigabytes of information, including information on specific citizens, from the clerk.county.suf domain.
What this Means?
Deals have slowed to a trickle since neither banks nor buyers can confirm that titles are clean — that is, the property is free of liens and that the seller is the legal owner and only owner — without checking the property out on county websites.
The process of filing claims is another problem. While some records supplied by hand are being accepted and preserved in chronological order, they won’t be officially on file until the systems are operational. Since New York is a “rush to record” state, the first party to file a title claim is the one whose claim is considered; hence incorrect document filing could result in significant issues.
According to Attorney Howard Stein, head of the Real Estate Practice Group at East Meadow-based Certilman Balin Adler & Hyman, the damage will increase exponentially. “New title reports cannot be created, and as a result, newly signed transactions are completely blocked.” The economic implications could be disastrous if a solution cannot be found.
Some title insurers have been forced to add an exception to their Schedule B list of things they cannot insure due to the closure of county systems. This exception now states that they will not cover “any defect, lien, encumbrance, adverse claim, or other matter created by or arising out of the inaccessibility of the Office of Suffolk County, including, but not limited to, an inability to search the public records, or any delay in recording of documents in the public records.”
According to Linda Haltman of Plainview-based Hallmark Abstract Services, “If they were in process before the hack and all of the title searches were done, they have been closing,” “Underwriters are letting sellers sign affidavits if the searches have already been conducted, with the exclusion of unoccupied land, new development, and foreclosures.”
Haltman warns that delays in closing can become costly given the fast-increasing mortgage rates.
“Delays in being able to close could be costly without an extension of a rate lock-in term,” she warned. “It could cost an extra $5,000 upfront to pay down the rate on a mortgage for a $500,000 house.”
Protected Harbor’s Take on the Matter
On September 8, websites and web-based apps for Suffolk Government were shut down after officials discovered malware in county systems. Images of county documents were posted as ransomware on the website DataBreaches.net. The hackers claimed to have taken court records, sheriff’s office records, contracts with the state, and citizen personal data from the county clerk’s website.
“An immediate resolution to this issue is critical, as there will be an increasing number of damages as a result of the shutdown,” Protected Harbor CEO Richard Luna said.
Earlier, most small and mid-sized enterprises were unaware of the importance of cybersecurity. However, with the increasing number of cyber-attacks, it has become imperative for all enterprises to invest in cybersecurity. As a company that provides enterprise-grade software, we have always ensured that all our products are secure.
The first step in a new network design is to limit through segmentation of the network. Desktops, Servers, and the backup should all be on separated and isolated networks. Using this approach, an infected desktop will not be able to access the backups and will not infect the backups.
Virtualization
We can accomplish desktop and network isolation using virtualization. Virtualization allows you to back up the entire desktop, not just shared folders, databases, or scanned folders, but all folders. This means we can recover the whole office, and not pieces of the office.
Email & Web Filtering
Filtering email and web content is an integral part of the Ransomware defense. Good email filtering should include pattern recognition. The initial Ransomware attacks follow a template, and when properly configured, email filtering systems block or quarantine the attack.
Enable network monitoring
Network monitors can alert and warn on unusual traffic or traffic that is typical of an attack; for example, if specific information is transmitted out of the network, that would trigger an alert.
Geo-Blocking
Maintain enhanced network protection that includes active parameter checking and Geo-Blocking. For example, check the address of inbound requests, and if the IP is from a blocked country, then the traffic is blocked even before it reaches the client’s network.
Cyber threats are increasing daily, and it is essential to stay protected against them. It is impossible to avoid cyber threats altogether, but we can stay protected by following specific steps and implementing the best cybersecurity practices.
Protected Harbor offers a range of cybersecurity products and services that protect your business against all types of malware, ransomware, and other cyber threats. It also ensures data integrity, regulatory compliance, and system availability.

Cybercrimes & Everything You Need to Protect Your Business
October marks the start of Cybersecurity Awareness Month. It started with President George W. Bush in 2004, to help individuals protect themselves online as threats to technology and confidential data become more commonplace. Now it is an annual event held globally every October.
The cybercrime business has become one of the most lucrative illegal ventures out there, showing no signs of slowing down. Over the past ten years, hackers have developed new and sophisticated ways of getting their hands on your most important data.
The unfortunate odds are that these cybercriminals will not be caught; meanwhile, consumers continue to face far more significant risks than ever before.
Why Is Cybercrime So Dangerous and Can You Be Safer?
If you are a small business using an off-the-shelf software, I’m sorry to inform you that you are at a higher risk of becoming a victim of cybercrime. We have all, at some point, received phishing emails or have been asked for personal information via our work email from people asking for something out of the ordinary. Most employees have work and personal information on either their company websites or social media. It’s one thing for your business to get scammed, but these bad actors will also go after your clients putting your reputation and business at risk. Fortunately, there are some things that you can do to keep yourself safer.
A criminal hacker can target any employee who uses social media. It’s fairly dangerous, but we at Protected Harbor have some tips. We harden our clients’ networks and run employee training all the time. The best thing to tell your employees is to not post anything online that you would not say to your competitors or your manager.
Several social networking sites, such as LinkedIn, allow users to post their resumes. Information concerning one’s work can reveal too much about one’s personal life, giving criminals such as hackers information that may enable them to hack into one’s account. Identity theft can also be committed using resume information.
The privacy settings on most social networking sites are either pre-set or default. Suggest your staff make an effort to alter their privacy settings to block strangers and people who are not friends with them from viewing their private information.
Protecting Yourself from Spyware and Viruses
Think about utilizing safe search online browsing software, frequently included in antivirus software complete editions. This software often uses a red, yellow, or green dot next to the links on the search engine. This aids in warning employees of potentially harmful websites.
Never download a torrent file or a software crack, and never download any file that doesn’t come from a reliable website. These frequently include malware. Also, do not click on any pop-up windows that you are not expecting. Instead, either close the window or get out of your browser completely.
Most importantly, make sure that you are updating your OS’s security patches and always have the latest version of your web browser installed. It sounds simple, but companies like Windows Defender push patches and updates daily to fix vulnerabilities. If you are not fast enough in updating the software, a hacker will use it as an entry point into your system.
Understanding Social Engineering
Generally, social engineering involves some type of deception to gather information to commit fraud or gain access to a computer. For instance, our google account uses Meta for Business to run our Facebook Page. Often, we will get a general email to our work email claiming our ads were blocked or taken down due to a violation. It would be tempting to open the email and click on such a link if we actually ran ads there.
Do you know what typosquatting is? Pay attention to the spelling of website addresses. They may resemble a real website, but instead, they are misspelled, for example, GOOGLE.com vs. G00GLE.com.
Any email including an offer of any kind should raise suspicions, especially if it seems too good to be true. The same applies to receiving offers from social media or reputable internet businesses, like Facebook and Google.
Caller ID Spoofing; What You Need to Know
“ID spoofing,” is another cybercrime you must be aware of. These days, a random phone call is more likely than ever to be a scammer. Criminals can fool people by hiding their information using “spoofing.” Spoofing disguises, the telephone number from which a text is sent by creating a new one. Phony numbers with the same area code are often used to persuade recipients to answer. The scary thing for businesses is that they can make it look like your number, and call clients.
All of your business numbers and extensions represent assets that you need to protect. Software like IntelePeer and Hiya Connect Secure Call can stop scammers from mimicking your phone numbers, regardless of how many lines and extensions you have in your internal network.
Is Public Wi-Fi Safe?
Unfortunately, public Wi-Fi is not secure. Several security risks are associated with using a public Wi-Fi. These networks broadcast signals through radio frequencies, which means that anyone who has the right tools, and these tools are fairly easy to find, can intercept the data that is sent through it.
To protect yourself when using public Wi-Fi, you should use either a remote desktop or virtual desktop. DO NOT USE A VPN!
A VPN (Virtual Private Network) helps you establish a private network while using any public networks. While beneficial to provide access to employees and third parties, this access is open-ended and unsecure. All security capabilities are lost when granting third parties’ remote access via VPN. VPNs lack access controls and session monitoring, both effective means of security for network access. VPNs don’t manage, vault, or verify credentials, so password protection depends on your third parties keeping them safe.
Remote desktop solutions are becoming increasingly familiar with the increased prevalence of distributed workforces and more employees regularly working from home. It’s perfect for people who are either frequently on the go, work out of a home office, or are often out in the field and need access to their local desktop computer. RDP is encrypted by default with a higher level of encryption than VPN and requires no additional connection time.
Even if you have a virtual desktop, don’t store any type of critical data on a device, and then use it outside of a network that is not secure. That means downloading documents to your cellphone, then connecting to Starbucks’ free Wi-Fi to watch TikTok. Turn off the Bluetooth and Wi-Fi on your cell phone or laptop when you aren’t using them, a device that can still send wireless signals appeals to a hacker.
What Is a Credit Freeze?
If you don’t have a credit freeze on your business bank account, you are putting your business at further risk. A credit freeze, sometimes called a security freeze, locks down a credit file so that a lender cannot check your credit. This is a good thing, as criminals cannot open any new accounts using your name or your EIN…and if a lender can’t check your credit, they are unlikely to extend a line of credit.
Remember that you must request a credit freeze from each credit bureau, including Equifax, Experian, Innovis, and TransUnion. Remember you can always un-freeze your accounts whenever needed.
Keeping Your Passwords Safe and Protected
The most important thing you need to know about passwords is that there is no secure password. Some passwords are more secure than others, of course, but they can always be found. Passwords are extremely convenient for people who want to access your accounts.
Is a Password Manager a Good Idea?
It’s hard to keep track of all your passwords, so it’s tempting to reuse the same one across the board. However, if a hacker gets possession of your password, they’ll have free access to everything you have. Password managers, on the other hand, can simplify your life.
It’s unsurprising for us to be asked, “are password managers safe to use?” The answer is, the use of password managers is considered to be one of the most secure ways to protect your passwords. Password managers offer strong protection against cybercrime because of their encryptions. AES, the industry-standard protection used by the U.S. government to safeguard its sensitive data, is just one example.
Set Up Two Factor Authentication on All Accounts
Password authentication is when a user enters a unique ID and key compared to previously stored credentials. It is one of the quickest forms of security; you can set up your device to require some identification before letting someone access your phone. It can be in a passcode, PIN, password, fingerprint, or two-factor authentication (2FA) can be adopted as well.
An additional layer of protection is provided by 2FA, which ensures that the user is whom they say they are. Before gaining access to the account, the user must first provide their username and password. The second piece of information is then requested. Almost every major company and organization website utilizes some kind of two-step, or two-factor, identification.
Protecting Your Credit Cards
Many of us, especially in today’s world, use credit cards for not only our jobs but even our daily lives, and there are several things you can do to protect yourself from credit card fraud.
First, make sure to examine your business credit card statements often to see whether they include any unfamiliar or strange expenses. Check your credit card accounts weekly if you can. Check for both large and small charges. If the hackers want to make a large purchase, they might make a small purchase to ensure it goes through.
You can also set up “push” alerts on your company accounts to receive notifications via email or text when purchases are made. For example, you may receive a text any time purchase over $100 is made, or an email anytime there is an online credit card transaction.
Also, store your credit card numbers online at your peril. It’s safer to manually enter the digits every time you want to purchase than to auto-input via Google or Apple.
Final Words
Many businesses have already installed firewalls, spam filters, and anti-virus software in order to prevent any cybercriminals from breaking in, yet they are still concerned – and we don’t blame them. These preventions are worthless without a dedicated IT team to respond to malicious attacks and fix compromised devices. If you are worried about ransomware or cyber-attacks, bringing in an experienced team to help with the rise in threats can provide a level of service beyond what firms currently have and at a lower cost.
Outside teams like Protected Harbor bring years of actionable experience to strengthen an organization.
We will ensure that your organization is protected from outside threats with well-tested, proven, and integrated technology. Protected Harbor concentrates on six elements throughout the stack, uplink, firewall, switches, hosts, VMs configuration, and storage to safeguard our customers’ operations.
What are the different types of viruses and ransomware?
In this digital age, viruses and ransomware are becoming a growing security concern for computer users. The threat of malicious software is real, and understanding the different types of viruses and ransomware is essential to protect yourself and your data. There are four main types of viruses, each with its own characteristics and potential harm. These include Trojans, bots, malware, and ransomware. With some basic knowledge, computer users can better protect themselves against these malicious programs. Knowing the differences between these types of viruses and their capabilities is the first step to keeping your computer safe and secure.
Virus:
A computer virus is a malicious code or program written to alter how a computer operates and is designed to spread from one computer to another. A virus operates by inserting or attaching itself to a legitimate program or document that supports macros to execute its code. In the process, a virus can potentially cause unexpected or damaging effects, such as harming the system software by corrupting or destroying data.
Two types of viruses causing headaches for security experts are multipartite virus and polymorphic virus. Multipartite viruses leverage multiple attack vectors to infiltrate systems, while polymorphic viruses cunningly change their code to evade detection. Understanding and defending against these sophisticated adversaries is crucial to safeguarding our digital world.
A macro virus is a malicious code quickly gaining popularity amongst hackers. It is a type of virus that replicates itself by modifying files containing macro language, which can replicate the virus. These can be extremely dangerous as they can spread from one computer to another and can cause damage by corrupting data or programs, making them run slower or crash altogether. Users need to take preventive measures against the threat of viruses, as they can eventually cause serious damage.
Worm:
A computer worm is a type of malware that spreads copies of itself from computer to computer and even operating system. A worm can replicate itself without any human interaction and does not need to attach itself to a software program to cause damage.
Ransomware:
The idea behind ransomware, a form of malicious software, is simple: Lock and encrypt a victim’s computer or device data, then demand a ransom to restore access.
In many cases, the victim must pay the cybercriminal within a set amount of time or risk losing access forever. And since malware attacks are often deployed by cyber thieves, paying the ransom doesn’t ensure access will be restored.
Ransomware holds your personal files hostage, keeping you from your documents, photos, and financial information. Those files are still on your computer, but the malware has encrypted your device, making the data stored on your computer or mobile device inaccessible.
Ransomware can spread across the Internet without specific targets since it’s one of the most common types of computer virus. But this file-encrypting malware’s nature means that cybercriminals can also choose their targets. This targeting ability enables cybercriminals to go after those who can — and are more likely to — pay larger ransoms.
Trojan:
A Trojan horse, or Trojan, is a type of malicious code or software that looks legitimate but can take control of your computer. A Trojan is designed to damage, disrupt, steal, or inflict some other harmful action on your data or network.
A Trojan acts like a bona fide application or file to trick you. It seeks to deceive you into loading and executing the malware on your device. Once installed, a Trojan can perform the action it was designed for.
A Trojan is sometimes called a Trojan or a Trojan horse virus, but that’s a misnomer. A Trojan cannot. A user has to execute Trojans. Even so, Trojan malware and Trojan virus are often used interchangeably.
Bots:
Bots, or Internet robots, are also known as spiders, crawlers, and web bots. While they may be utilized to perform repetitive jobs, such as indexing a search engine, they often come in the form of malware. Malware bots are used to gain total control over a computer.
The Good
One of the typical “good” bots used is to gather information. Bots in such guises are called web crawlers. Another “good” use is automatic interaction with instant messaging, instant relay chat, or assorted other web interfaces. Dynamic interaction with websites is yet another way bots are used for positive purposes.
The Bad
Malicious bots are defined as self-propagating malware that infects its host and connects back to a central server(s). The server functions as a “command and control center” for a botnet or a network of compromised computers and similar devices. Malicious bots have the “worm-like ability to self-propagate” and can also:
Gather passwords
Obtain financial information
Relay spam
Open the back doors on the infected computer
Malware:
Malware is an abbreviated form of “malicious software.” This is software specifically designed to gain access to or damage a computer, usually without the owner’s knowledge. There are various types of malware, including spyware, ransomware, viruses, worms, Trojan horses, adware, or any malicious code that infiltrates a computer.
Each type of malware has its own purpose and potential impacts, making it important to be aware of the different types of malware. We can protect ourselves from these malicious software threats with the right knowledge and resources.
Generally, the software is considered malware based on the creator’s intent rather than its actual features. Malware creation is rising due to money that can be made through organized Internet crime. Originally malware was created for experiments and pranks, but eventually, it was used for vandalism and destruction of targeted machines. Today, much malware is created to make a profit from forced advertising (adware), stealing sensitive information (spyware), spreading email spam or child pornography (zombie computers), or extorting money (ransomware).
The best protection from malware — whether ransomware, bots, browser hijackers, or other malicious software — continues to be the usual preventive advice: be careful about what email attachments you open, be cautious when surfing by staying away from suspicious websites, and install and maintain an updated, quality antivirus program.
Spyware:
Spyware is unwanted software that infiltrates your computing device, stealing your internet usage data and sensitive information. Spyware is classified as a type of malware — malicious software designed to gain access to or damage your computer, often without your knowledge. Spyware gathers your personal information and relays it to advertisers, data firms, or external users.
Spyware is used for many purposes. Usually, it aims to track and sell your internet usage data, capture your credit card or bank account information, or steal your personal identity. How? Spyware monitors your internet activity, tracking your login and password information, and spying on your sensitive information.
Security can be termed as protection from unwanted harm or unwanted resources. Information security protects the data from unauthorized users or access. It can also be termed as an important asset for any organization which plays a vital role. In earlier days it was difficult to identify ransomware before it enters or attacks the user’s system. These attacks would damage the mail servers, databases, expert systems, and confidential systems. In this paper, we propose the analysis and detection of ransomware which will have a major impact on business continuity.
RANSOMWARE
Lately, with the extensive usage of the internet, cybercriminals are rapidly growing targeting naïve users thru threats and malware to generate a ransom. Currently, this ransomware has become the most agonizing malware. Ransomware comprises of two. They are locker ransomware and crypto-ransomware. Of them, crypto-ransomware is the most familiar type that aims to encrypt users‟ data and locker ransomware prevent the users from accessing their data by locking the system or device. Both types of a ransomware demand a ransom payable via electronic mode for restoring the access of the data and system. Locker ransomware claims fee from the victims in terms of fine for downloading illegal content as per their fake law enforcement notice. Crypto ransomware has a time limit that warns the victims to pay the ransom within the given time else the data will be lost forever.
Spreading of ransomware is possible by the following methods:
Phishy e-mail messages with malicious file attachments;
Software patches that download the threat into the victim’s machine whilst working online.
Phishing emails: The most common way of spreading Ransomware is thru phishing emails or spam emails. These mails include a .exe file or an attachment, which when opened launches ransomware on the victim’s machine.
Exploit kits: these are the compromised websites planned by the attackers for malicious use. These exploit kits search for vulnerable website visitors to download the ransomware onto their machine.
VULNERABILITY ASSESSMENT AND TOOLS
The vulnerability can be termed as unsafe or unauthorized access by an intruder into an unprotected or exposed network. Common vulnerabilities are worms, viruses, spyware applications, spam emails, etc. Vulnerability Assessment is the most important technique that is conducted to rate the spontaneous attacks or risks that occur in the system thereby affecting the business continuity of an organization. Vulnerability assessment has many steps such as
Vulnerability analysis
Scope of the vulnerability assessment
Information gathering
Vulnerability identification
Information Analysis and
Planning
Assessment Tools
Vulnerability assessment which is nothing but testing can be carried out by best-known tools which are called vulnerability assessment tools. These tools are used to mitigate the identified vulnerabilities such as investigating unethical access to copyrighted materials, policy violations of the organizations‟ etc. The red alert issue about the vulnerability assessment is that it warns us about the vulnerability before the system is compromised and helps us in avoiding or preventing the attack. These vulnerability assessment tools can also be categorized as proactive security measures of an organization. The major step of the vulnerability assessment is the accurate testing of a system. The major step of the vulnerability assessment is the accurate testing of a system. If overlooked, it might lead to either false positives or false negatives. False-positive can be presumed as quicksand where we can’t find what we are searching for. False-negative can be presumed as a black hole where we don’t know what we want to search for. False positives can be rated as a significant level in testing.
Common Vulnerability Assessment Tools
Vulnerabilities are the most crucial part of information systems. An error in configuration or violation of a policy might compromise a network in an organization. These attacks can be for personal gain or corporate gain.
Not only the local area networks but also the websites are also more susceptible to attacks where the systems can be exploited either by the insiders or outsiders of an organization.
Some of the very commonly used vulnerability assessment tools are listed below:
Wireshark
Nmap
Metasploit
OpenVAS
AirCrack
Limitations of Existing Vulnerability Assessment Tools
The concept of false positives is the dangerous and horrendous limitation of the existing vulnerability assessment tools. These false positives require lots of testing and study for assessing the nature of the errors that occurred, which is a very expensive and time taking process. All the identification-related information mostly leads to false positives.
Penetration Testing
Penetration Testing also called as Pen Test is an attempt to assess a malicious activity or any security breach by exploiting the vulnerabilities.
It includes the testing of the networks, security applications and processes that are involved in the network.
Penetration testing is done to improve the performance of the system by testing the system’s efficiency.
Ransomware is a type of malware (malicious software) that threatens to publish or prevent access to data or a computer system, typically by encrypting it. The victim is faced with the ultimatum of either paying a ransom or risking the publication or permanent loss of their data or access to their system. The ransom demand usually involves a deadline. If the victim doesn’t pay on time, the data is permanently lost, or the ransom is increased.
Attacks using ransomware are all too frequent these days. It has affected both large firms in North America and Europe. Cybercriminals will target any customer or company, and victims come from every sector of the economy.
The FBI and other government agencies, as does the No More Ransom Project, advise against paying the ransom to prevent the ransomware cycle because it doesn’t ensure retrieval of the encrypted data. If the ransomware is not removed from the system, 50% of the victims who pay the ransom will likely experience further attacks.
The first known attack was initiated in 1989 by Joseph Popp, Ph.D., an AIDS researcher, who attacked by distributing 20,000 floppy disks to AIDS researchers spanning more than 90 countries, claiming that the disks contained a program that analyzed an individual’s risk of acquiring AIDS through the use of a questionnaire.
However, the disk also contained a malware program that initially remained dormant in computers, only activating after a computer was powered on 90 times. After the 90-start threshold was reached, the malware displayed a message demanding a payment of $189 and another $378 for a software lease. This ransomware attack became known as the AIDS Trojan or the PC Cyborg.
There will be no end to ransomware anytime soon. Ransomware as a service raas attacks have skyrocketed in 2021 and will continue to rise. About 304.7 million ransomware attacks were attempted in the first half of 2021, and many attacks went unreported as per Ransomware statistics 2021.
A recent report by Tripwire supported the fact that ransomware will keep growing, and the post-ransomware costs will keep climbing significantly. There’s no denying the fact that Ransomware is being used as a weapon, and how ransomware spreads is no longer a mystery.
Modern-day attacks target operational technology, operating system, medical and healthcare services, third-party software, and IoT devices. Fortunately, organizations don’t have to be sitting ducks; they can minimize the risk of attacks by being proactive and having a reliable ransomware data recovery infrastructure.
Top Ransomware Attacks
1. Kia Motors
Kia Motors America (KMA) was hit by a ransomware attack in February that hit both internal and customer-facing systems, including mobile apps, payment services, phone services, and dealership systems. The hack also impacted customers’ IT systems that were required to deliver new vehicles.
DoppelPaymer was thought to be the ransomware family that hit Kia, and the threat actors claimed to have also targeted Kia’s parent business, Hyundai Motors America. Similar system failures were also experienced by Hyundai.
On the other hand, Kia and Hyundai denied being assaulted, a frequent approach victims use to protect their reputation and customer loyalty.
2. CD Projekt Red
In February 2021, a ransomware attack hit CD Projekt Red, a video game studio located in Poland, causing significant delays in developing their highly anticipated next release, Cyberpunk 2077. The threat actors apparently stole source codes for numerous of the company’s video games, including Cyberpunk 2077, Gwent, The Witcher 3, and an unpublished version of The Witcher 3.
According to CD Projekt Red, the unlawfully obtained material is currently being distributed online. Following the incident, the company installed many security measures, including new firewalls with anti-malware protection, a new remote-access solution, and a redesign of critical IT infrastructure, according to the company.
3. Acer
Acer, a Taiwanese computer manufacturer, was hit by the REvil ransomware outbreak in March. This attack was notable because it demanded a ransom of $50,000,000, the greatest known ransom to date.
According to Advanced Intelligence, the REvil gang targeted a Microsoft Exchange server on Acer’s domain before the attack, implying that the Microsoft Exchange vulnerability was weaponized.
4. DC Police Department
The Metropolitan Police Department in Washington, D.C., was hit by ransomware from the Babuk gang, a Russian ransomware syndicate. The police department refused to pay the $4 million demanded by the group in exchange for not exposing the agency’s information and encrypted data.
Internal material, including police officer disciplinary files and intelligence reports, was massively leaked due to the attack, resulting in a 250GB data breach. Experts said it was the worst ransomware attack on a police agency in the United States.
5. Colonial Pipeline
The Colonial Pipeline ransomware assault in 2021 was likely the most high-profile of the year. The Colonial Pipeline transports roughly half of the fuel on the East Coast. The ransomware attack was the most significant hack on oil infrastructure in US history.
On May 7, the DarkSide group infected the organization’s computerized pipeline management equipment with ransomware. DarkSide’s attack vector, according to Colonial Pipeline’s CEO, was a single hacked password for an active VPN account that was no longer in use. Because Colonial Pipeline did not use multi-factor authentication, attackers could access the company’s IT network and data more quickly.
6. Brenntag
In May, Brenntag, a German chemical distribution company, was also struck by a DarkSide ransomware attack around the same time as Colonial Pipeline. According to DarkSide, the hack targeted the company’s North American business and resulted in the theft of 150 GB of critical data.
They got access by buying stolen credentials, according to DarkSide affiliates. Threat actors frequently buy stolen credentials — such as Remote Desktop credentials — on the dark web, which is why multi-factor authentication and detecting unsafe RDP connections are critical.
The first demand from DarkSide was 133.65 Bitcoin, or nearly $7.5 million, which would have been the highest payment ever made. Brenntag reduced the ransom to $4.4 million through discussions, which they paid.
7. Ireland’s Health Service Executive (HSE)
In May 2021, a variation of Conti ransomware infected Ireland’s HSE, which provides healthcare and social services. The organization shut down all of its IT systems after the incident. Many health services in Ireland were impacted, including the processing of blood tests and diagnoses.
The firm refused to pay the $20 million ransom in Bitcoin because the Conti ransomware group provided the software decryption key for free. However, the Irish health service was still subjected to months of substantial disruption as it worked to repair 2,000 IT systems that had been infected by ransomware.
8. JBS
Also, in May 2021, JBS, the world’s largest meat processing plant, was hit by a ransomware attack that forced the company to stop the operation of all its beef plants in the U.S. and slow the production of pork and poultry. The cyberattack significantly impacted the food supply chain and highlighted the manufacturing and agricultural sectors’ vulnerability to disruptions of this nature.
The FBI identified the threat actors as the REvil ransomware-as-a-service operation. According to JBS, the threat actors targeted servers supporting North American and Australian IT systems. The company ultimately paid a ransom of $11 million to the Russian-based ransomware gang to prevent further disruption.
9. Kaseya
Kaseya, an IT services company for MSP and enterprise clients, was another victim of REvil ransomware — this time during the July 4th holiday weekend. Although only 1% of Kaseya’s customers were breached, an estimated 800 to 1500 small to mid-sized businesses were affected through their MSP. One of those businesses included 800 Coop stores, a Sweden-based supermarket chain that was forced to temporarily close due to an inability to open their cash registers.
The attackers identified a chain of vulnerabilities — ranging from improper authentication validation to SQL injection — in Kaseya’s on-premises VSA software, which organizations typically run in their DMZs. REvil then used MSP’s Remote Monitoring and Management (RMM) tools to push out the attack to all connected agents.
10. Accenture
The ransomware gang LockBit hit Accenture, the global tech consultancy, with an attack in August that resulted in a leak of over 2,000 stolen files. The slow leak suggests that Accenture did not pay the $50 million ransom.
According to CyberScoop, Accenture knew about the attack on July 30 but did not confirm the breach until August 11, after a CNBC reporter tweeted about it. CRN criticized the firm for its lack of transparency about the attack, saying that the incident was a “missed opportunity by an IT heavyweight” to help spread awareness about ransomware.
Bonus: CNA Financial (2021)
CNA Financial, the seventh largest commercial insurer in the United States, announced on March 23, 2021, that it had “experienced a sophisticated cybersecurity attack.” Phoenix Locker ransomware was used in the attack, which was carried out by a group called Phoenix.
CNA Financial paid $40 million in May 2021 to regain access to the data. While CNA has been tight-lipped about the specifics of the negotiation and sale, it claims that all of its systems have been fully restored since then.
Crypto ransomware encrypts files on a computer so the user cannot access them.
Locker Ransomware
Does not encrypt files. Rather, it locks the victim out of their device, preventing them from using it. Once they are locked out, cybercriminals carrying out locker ransomware attack demands a ransom to unlock the device.
Now you understand what ransomware is and the two main types of ransomware that exist. Let’s explore 10 types of ransomware attacks to help you understand how different and dangerous each type can be.
Locky
Locky is a type of ransomware that was first released in a 2016 attack by an organized group of hackers. With the ability to encrypt over 160 file types, Locky spreads by tricking victims to install it via fake emails with infected attachments. This method of transmission is called phishing, a form of social engineering. Locky targets a range of file types that are often used by designers, developers, engineers, and testers.
WannaCry
WannaCry is a ransomware attack that spread across 150 countries in 2017. Designed to exploit a vulnerability in Windows, it was allegedly created by the United States National Security Agency and leaked by the Shadow Brokers group. WannaCry affected 230,000 computers globally. The attack hit a third of hospital trusts in the UK, costing the NHS an estimated £92 million. Users were locked out and a ransom was demanded in the form of Bitcoin. The attack highlighted the problematic use of outdated systems, leaving the vital health service vulnerable to attack. The global financial impact of WannaCry was substantial -the cybercrime caused an estimated $4 billion in financial losses worldwide.
Bad Rabbit
Bad Rabbit is a 2017 ransomware attack that spread using a method called a ‘drive-by’ attack, where insecure websites are targeted and used to carry out an attack. During a drive-by ransomware attack, a user visits a legitimate website, not knowing that they have been compromised by a hacker. Drive-by attacks often require no action from the victim, beyond browsing the compromised page. However, in this case, they are infected when they click to install something that is malware in disguise. This element is known as a malware dropper. Bad Rabbit used a fake request to install Adobe Flash as a malware dropper to spread its infection.
Ryuk
Its a ransomware, which spread in August 2018, disabled the Windows System Restore option, making it impossible to restore encrypted files without a backup. Ryuk also encrypted network drives. The effects were crippling, and many organizations targeted in the US paid the demanded ransoms. August 2018 reports estimated funds raised from the attack were over $640,000.
Troldesh
The Troldesh ransomware attack happened in 2015 and was spread via spam emails with infected links or attachments. Interestingly, the Troldesh attackers communicated with victims directly over email to demand ransoms. The cybercriminals even negotiated discounts for victims with who they built a rapport with — a rare occurrence indeed. This tale is the exception, not the rule. It is never a good idea to negotiate with cybercriminals. Avoid paying the demanded ransom at all costs as doing so only encourages this form of cybercrime.
Jigsaw
Jigsaw is a ransomware attack that started in 2016. This attack got its name as it featured an image of the puppet from the Saw film franchise. Jigsaw gradually deleted more of the victim’s files each hour that the ransom demand was left unpaid. The use of horror movie imagery in this attack caused victims additional distress.
CryptoLocker
CryptoLocker is ransomware that was first seen in 2007 and spread through infected email attachments. Once on your computer, it searched for valuable files to encrypt and hold to ransom. Thought to have affected around 500,000 computers, law enforcement, and security companies eventually managed to seize a worldwide network of hijacked home computers that were being used to spread Cryptolocker. This allowed them to control part of the criminal network and grab the data as it was being sent, without the criminals knowing. This action later led to the development of an online portal where victims could get a key to unlock and release their data for free without paying the criminals.
Petya
Petya (not to be confused with ExPetr) is a ransomware attack that first hit in 2016 and resurged in 2017 as GoldenEye. Rather than encrypting specific files, this vicious ransomware encrypts the victim’s entire hard drive. It does this by encrypting the primary file table, making accessing files on the disk impossible. Petya spread through HR departments via a fake job application email with an infected Dropbox link.
GoldenEye
The resurgence of Petya, known as GoldenEye, led to a global ransomware attack that happened in 2017. Dubbed WannaCry’s ‘deadly sibling,’ GoldenEye hit over 2,000 targets, including prominent oil producers in Russia and several banks. Frighteningly, GoldenEye even forced workers at the Chernobyl nuclear plant to check radiation levels manually as they had been locked out of their Windows PCs.
GandCrab
GandCrab is a rather unsavory famous ransomware attack that threatened to reveal the victim’s porn-watching habits. Claiming to have a high-jacked user’s webcam, GandCrab cybercriminals demanded a ransom, or otherwise, they would make the embarrassing footage public. After having first hit in January 2018, GandCrab evolved into multiple versions. As part of the No More Ransom Initiative, internet security providers and the police collaborated to develop a ransomware decryptor to rescue victims’ sensitive data from GandCrab.
You now know about the various types of ransomware attacks that have been perpetrated against individuals and businesses in recent years. Many of the victims of the ransomware attacks we’ve mentioned became infected after clicking on links in spam or phishing emails or opening malicious attachments.
So, how can you avoid being a victim of a ransomware assault if you receive a ransomware email? Checking the sender is the easiest approach to recognizing a ransomware email. Is it from a reliable source? Always be cautious if you receive an email from someone or a firm you don’t recognize.
Never open email attachments from senders you don’t trust, and never click on links in emails from untrustworthy sources. If the attachment asks you to activate macros, proceed with caution. This is a popular method of ransomware distribution.
Using a Ransomware Decryptor
Do not pay a ransom if you are the victim of a ransomware assault. Paying the ransom demanded by cybercriminals does not guarantee that your data will be returned. After all, these are crooks. It also strengthens the ransomware industry, increasing the likelihood of future assaults. You will be able to restore the data that is being held to ransom if it is backed up outside or in cloud storage.
Types of Ransomware Extensions
The ransomware includes a particular file extension, you can point it out with some of the extensions defined below
Tips to Protect yourself against Ransomware attacks
It is becoming more difficult to prevent ransomware attacks, event large IT departments can have difficulty, just ask Sony, the City of Baltimore, or the City of Atlanta.
For the last 40 years, we have built networks and office systems with the concept of sharing data. Shared folders for example make it easy for users to exchange and edit documents, but also those shared folders are the target of Ransomware attacks.
Some tools can be added to reduce the likelihood of ransomware, but nothing can be purchased to “protect” a company.
The most effective protection for Ransomware starts with a network and desktop redesign followed by layers of security and isolated backups. The best approach is not to try to protect against Ransomware, it is to develop a plan that minimized the impact of an attack. Unfortunately, many of the steps listed below require a desktop or office changes and many organizations are unwilling to change.
At Protected Harbor we will not onboard a client without making the changes needed to protect against Ransomware. We think a new reality is that only good network design and good governance can keep networks safe. Most small IT companies are ill-equipped to understand the depth of the risk, much less take the necessary steps to protect against Ransomware.
The end-user resistance to change combined with tight IT budgets and the concept that IT is low cost has created a climate of a one-stop drop-in application or solution to stop all IT problems. This approach will not work to stop Ransomware. In short at Protected Harbor we protect our clients through better design.
Ways to PROTECT YOUR SYSTEM FROM RANSOMWARE
Below are the steps we take to protect our clients and we recommend the steps are deployed by all organizations.
Desktop/Network & Backup Isolation
The first step in a new network design is to limit through segmentation the network. Desktops, Servers and the backup should all be on separated and isolated networks. Using this approach an infected desktop will not be able to access the backups and will not infect the backups.
Protected Harbor will accomplish desktop and network isolation using virtualization. Virtualization allows Protected Harbor to back up the entire desktop, not just shared folders, or databases, or scanned folders, but all folders. This means we can recover the entire office, and not pieces of the office.
Email & Web Filtering
Filtering of email and web content is an important part of the Protected Harbor Ransomware defense. Good email filtering should include pattern recognition. The initial Ransomware attacks follow a template and email filtering systems when properly configured either block or quarantine the attack.
Enable network monitoring
We monitor for inbound and outbound traffic, which allows us to react to attack patterns in addition to standard monitoring. Network monitors can alert and warn on unusual traffic, or traffic that is typical of an attack; for example, if certain information is transmitted out of the network that would trigger an alert. We protect our customers by constantly monitoring network traffic, especially activity to or from parts of the world that are high sources of attacks, for example, Russia or China. We also monitor and alert on traffic flow. Oftentimes, if an end-user connects an infected phone or laptop to the network, we will see a change in the traffic flow which will trigger an alert.
Above is a sample of our traffic monitoring.
Tighten local server/desktop permissions
Our clients do not run their programs as Administrators. Enhancing the security drastically reduces a ransomware attack and virtually eliminates malware attacks. Enhanced security reduces what an attack can affect through better design.
Reduce the number of common shares folders
Typically, clients will have one or two shared folders that all users have access to. Ransomware attacks not only infect those shares but then use them to spread the attack to other non-infected systems. We work with clients to reduce or eliminate shared folders, increasing the protection through better design to ransomware.
Reduce public corporate contact information
Live email addresses should not be published on a website. If a website needs an email address, the published address shouldn’t use the same format as the internal address. If jsmith is the email prefix, as in jsmith@abc.com then for the website the published email should be jacksmith@abc.com. Additionally, sensors can be added to the content filter for petersmith@abc.com for example. This would mean the attacking IP (the one attempting to send email to petersmith@abc.com) is really a robot attacker; adding that IP to the block list would prevent all future attacks from occurring.
Parameter or Geo Blocking
For our clients we maintain enhanced network protection that includes active parameter checking and Geo-Blocking. For example, we check the address of inbound requests, and if the IP is from a blocked country, then the traffic is blocked even before it reaches the client’s network. Countries we routinely block are North Korea, Russia and countries are known for sending out Ransomware attacks. If access is needed from a blocked country, a simple support ticket resolves the issue.
Testing & Training
At Protected Harbor we perform routine simulated Ransomware attacks. These tests are productive at helping end user stay vigilant to attacks and the tests allow end users to be identified that might need some additional assistance to understand the importance of being careful with email.
“We guarantee we can PROTECT YOU FROM RANSOMWARE!”
Any vendor that says that or implies that is lying. There is no one magic happy pill, service, or device to stop ransomware. When done right guarding against ransomware is a combination of multiple technologies, backups, education good layered network design and human intervention.
Protected Harbor is a unique vendor because we don’t resell other company services, we engineer our own solutions. That depth of knowledge is a foundational difference between us and anyone else. The depth of technical ability allows us to write this document and solve the problem at the core and not band-aid the problem as others do.
Ransomware is malicious software that targets computer systems and locks down important data until a ransom is paid. Ransomware is an increasingly prevalent form of cyber-attack, which can cause serious disruption to businesses and individuals alike. It works by malicious actors encrypting a victim’s data and then demanding a ransom payment in order to restore access to it. Organizations must take active steps toward ransomware protection and prevention, as the costs associated with a successful attack can be substantial. Investing in robust IT security measures, such as antivirus software and regular backups, will significantly reduce the risk of becoming a target. Furthermore, ensuring employees have the necessary understanding of ransomware prevention techniques will help protect your organization from this form of cyber-attack.
What is a Ransomware attack?
Ransomware is the encryption of files, without knowing the password, and most of the time the encryption is self-executed for local files, network files and operating system files combined with Trojan installations to enable later additional data theft or additional attacks.
Most of us have used or made a password protected ZIP file before. ZIP files are a form of encrypted and compressed files. The encryption and compression process
works by mathematically removing the empty and repeated characters in the data using password. The mathematical formula uses the password as a seed and applies a
compression algorithm to the data, securing and reducing the data. Using this technique, a ZIP file is both secure, because without the password it can’t be decrypted and smaller in size.
A Ransomware attack at its core is where the organizations data files have been encrypted using a similar technique to a password protected ZIP file. Typically,
ransomware attacks encrypt one file at a time. Ransomware attacks can be devastating because the data once encrypted is not recoverable. Initially versions of ransomware attacks targeted local files on local computers, but more recent attacks have caused greater damage by targeting network folders and operating system files.
Once an operating system file is infected the server or PC will never work right and should be totally reformatted and recreated.
Ransomware attacks also attempt to install infected files, also called Trojans. The Trojans are used to later attack the computer or server again and or are used to
monitor the infected system to steal data. Some Trojans don’t directly attack but instead run in background monitoring and sending new data. This is what occurred at the Sony attack; Modern cleaning tools like Malwarebytes do a good job at removing infected cookies and web attacks but do not clean operating system files very well, which is why we always recommend not cleaning a PC or Server but rebuilding it.
How does a Ransomware attack occur?
But how did it occur? How did it get in? Virtually all of the time the attack is self-started, meaning the attack was triggered by a trusting employee. Most Ransomware attacks start via email. An external email server or email account is compromised, and the compromised account is then used to send out infected emails.
Image is an example. The email itself it not infected. The email account is legitimate, and at the time the email server amegybank.com was not flagged as a spammer – meaning this email would have passed through most firewalls, filters and blocking services.
The infection is the attached HTML file. The attached HTML file is the payload. The HTML file will look to many anti-virus programs as a web cookie or bot, i.e. a
legitimate attachment. Bots or payloads can take many forms, Macros in Word, Excel or PDF files are typically used.
A payload is a small piece of programming code designed to look like a legitimate web from a web site. Once the end-user clicks on the attachment the payload is activated. Once active the payload will download from a remote site the actual attack. The attack will be a larger program that is also designed to slip through firewalls and content filters, this program will start to encrypt files and also will look for links to remote data, either remote server (RDP for example) login information, web site links with stored passwords, FTP or STP file transfer links, virtually any form of data connection is attempted. The attack is designed to find as much data as is possible, the more data that is encrypted the more the infected company is willing to pay.
Keeping Your Passwords Safe and Protected
