What is a Privilege Escalation attack? How to prevent them?

Privilege escalation is a vulnerability used to access applications, networks, and mission-critical systems. And privilege escalation attacks exploit security vulnerabilities and progressively increase criminal access to computer systems. These attacks are classified into vertical and horizontal privilege escalation based on the attack’s objective and strategy. There are several types of privilege escalation attacks, and each of them exploits a unique set of vulnerabilities having its own set of technical requirements.

Where there are privileges, there are ways to subvert them. Privilege escalation attacks are methods of gaining access to restricted privileges in system services or programs. This article covers the various types of privilege escalation attacks, the types and impact of these attacks, and how to prevent them and prevent yourself from being exploited.

What is a Privilege Escalation attack?

Privilege escalation is a common method attackers use to gain unauthorized access to systems and networks within a security perimeter. Many organizations face an attack vector due to a loss of focus on permissions. As a result, existing security controls within organizations are often insufficient to prevent attacks. Attackers initiate privilege escalation attacks by detecting the weak points in an organization’s IT infrastructure.

Privilege escalation attacks occur when a malicious actor gains access to a user account, bypasses the authorization channel, and successfully accesses sensitive data. The attacker can use obtained privileges to execute administrative commands, steal confidential data, and cause severe damage to server applications, operation systems, and the company’s reputation. While deploying these attacks, attackers are generally attempting to disrupt business functions by exfiltrating data and creating backdoors.

How Do Privilege Escalation attacks Work?

Privilege escalation attacks represent the layer of a cyberattack chain where criminals take advantage of a vulnerable system to access data from an unauthorized source. However, there are various weak points within a system, but some common entry points include Application Programming Interfaces and Web Application Servers. Attackers authenticate themselves to the system by obtaining credentials or bypassing user accounts to initiate the attack. Apart from it, attackers find different loopholes in account authorization access to sensitive data.

Regrading how a privilege escalation attack works, attackers usually use one of these five methods: credential, system vulnerabilities, and exploits, social engineering, malware, or system misconfigurations. By implementing one of these techniques, malicious actors can gain an entry point into a system. Depending on their goals, they can continue to uplift their privileges by taking control of a root or administrative account.

Common Privilege Escalation Attacks Examples

Here are some common examples of real-world privilege escalation attacks.

• Windows Sticky Keys_ It’s one of the most common examples of privilege escalation attacks for Windows operating systems. This attack requires physical access to the targeted system and the ability to boot from a repair disk.
• Windows system internals_ commands provide a source of privilege escalation attacks in Windows. This method assumes that the attacker has a backdoor from a previous attack, such as Windows sticky keys method. The attacker must have access to local administrative rights and then logs into backdoor accounts to escalate permissions to the system level.
• Android and Metasploit_ Metasploit is a well-known tool, including a library of known exploits. This library contains the privilege escalation attack against rooted android devices. It creates an executable file called superuser binary, allowing attackers to run commands with administrative or root access.

Privilege Escalation attack techniques

The goal of the privilege escalation attack is to get high-level privileges and find entry points to critical systems. There are various techniques attackers use for privilege escalation. Here are three of the most common ones.

• Bypass user account control_ The user account control is a bridge between users and administrators. It restricts application software to standard permissions until an admin authorizes privilege increase.
• Manipulating access tokens_ In this case, the attacker’s main task is to trap the system into believing that the running processes belong to another user other than the authorized user that started the process.
• Using valid accounts_ Criminals can leverage credential access techniques to get credentials of certain user accounts or streal them using social engineering. Once attackers access the organization’s network, they can use these credentials to bypass access control on IT systems and various resources.

What Are The Types Of Privilege Escalation Attacks?

There are two types of privilege escalation attacks. These include

1. Horizontal privilege escalation

It’s a type of attack in which attackers expand their privileges by taking control of another account and misusing the authorized rights granted to the legitimate user. Phishing campaigns are used to gain access to user accounts. For elevating the permissions, attackers either exploit vulnerabilities in the OS to gain root-level access or leverage hacking tools, such as Metasploit.

2. Vertical privilege escalation

This type of attack occurs when a criminal gains direct access to an account with the intent to perform similar actions as the legit user. A vertical privilege attack is easier to achieve as there is no desire to elevate permissions. In this scenario, the attack focuses on account identification with necessary privileges and gaining access to that account.

Impact of Privilege Escalation Attack

Privilege escalation attacks can impact in the following ways.

• It can enter the organization’s IT infrastructure
• Modify permissions to steal sensitive information
• Add, delete, or modify users
• Create a backdoor for future attacks
• Gain access to systems and files and disrupt the operations
• Crash the website

How to prevent Privilege Escalation attacks?

Here are some best practices to prevent privilege escalation attacks.

1. Protect and scan your systems, network, and application. You can use effective vulnerability scanning tools to detect insecure and unpatched operating systems, applications, weak passwords, misconfigurations, etc.
2. It’s essential to manage privileged accounts and ensure their security. The security team needs an inventory of all accounts where they exist and their purpose.
3. Establish and enforce robust policies to ensure that users and strong and unique passwords. Use multi-factor authentication to add an extra security layer while overcoming vulnerabilities arising due to weak passwords.
4. Users are the weakest link in the security chain, putting the entire organization at risk. Businesses should implement robust security awareness programs with effective training.
5. Secure databases and sanitize user inputs. Databases are attractive targets of criminals as web applications store all their data in databases, such as login credentials, configuration settings, and user data. With one successful attack, such as SQL injection, criminals can access all sensitive information and leverage it for further attacks.

Conclusion

Privilege escalation attacks are a significant problem. They can easily create havoc, with the attack escalating from one user to the entire system. The most important thing you can do is be aware of the different privilege escalation types and be sure not to give access to anything on your computer or network that you don’t need.

What Iran’s Cyber Attack On Boston Children’s Hospital Means For Your Healthcare Organization

Wednesday, June 1^st, At a Boston College cybersecurity conference hosted by Mintz, FBI Director Christopher Wray stated that investigators prevented a planned attack on Boston Children’s Hospital by Iranian government-sponsored hackers. The FBI director told the story as part of a bigger speech about cyber threats from Russia, China, and Iran, as well as the importance of government-private partnerships.

What Happened

In the summer of 2021, the FBI received a tip from an intelligence partner that hackers sponsored by the Iranian government were targeting the Boston Children’s Hospital. The cyber squad in the FBI Boston Field Office raced to notify the hospital. Over a 10-day period, worked with the hospital in response to the threat

Wray didn’t say why the hospital attack was planned, but he did say that Iran and other governments have been hiring cyber mercenaries to carry out attacks on their behalf. Furthermore, the US government has identified the healthcare and public-health sectors as one of 16 critical infrastructure sectors. Healthcare providers such as hospitals are considered easy targets for hackers.

It wasn’t clear if the hackers planned to target the hospital with ransomware, shut down the hospital operations with a virus, or sell the data on the black market.  That’s because the FBI caught the attack early enough to prevent any damage to the network or the hospital’s data. The FBI declined to discuss the specific nature of the attack in detail, citing security reasons.

Nevertheless, the FBI issued a warning in November saying Iranian government hackers had breached the “environmental control network” at an unidentified children’s hospital in the United States last June. Leading many to assume the same was targeted in Boston. The environmental control network refers to the hospital’s HVAC system.

What it Means

In the case of ransomware, hospitals can face devastating system shutdowns. Patient data can be made inaccessible to hospital staff, it can be damaged, or it can be stolen and sold. A ransomware attack compromised a Vermont hospital’s patient record system in October 2020, and patients have turned away as a result.

Nation-states and hacker groups are probing healthcare organizations and looking for areas to exploit. This past November, the Cybersecurity and Infrastructure Security Agency issued an alert for an Iran-sponsored hacker group targeting healthcare. As the Russia-Ukraine war drags on, federal agencies say U.S. healthcare organizations need to be “shielded up” to mitigate against potential foreign threats.

The FBI is “racing” to warn possible healthcare targets of data breaches when it comes to Russia and other state-sponsored attacks. According to Wray, China’s hackers have stolen more business and personal data from Americans than all other countries combined as part of an enormous geopolitical ambition to “lie, cheat, and steal their way into global denominations of global industries.”

All hospitals and healthcare organizations must sit up and take notice. It is not only hacktivist groups and employees they need to worry about, today. But nation-states as well.

Protected Harbor’s Take On The Issue

Protected Harbor has been monitoring the situation for a long time and continues to emphasize cybersecurity. Richard Luna, CEO of Protected Harbor, said this is a severe issue, and we advise all our clients to take precautionary measures and make sure their systems are secure and protected.

He suggested 3 simple tips to harden your servers, which every company should implement immediately.

1. Update the operating systems on your servers regularly.

The most crucial action you can take to secure your servers is to keep their operating systems up to date. On a nearly daily basis, new vulnerabilities are discovered and publicized, with the potential for remote code execution or local privilege escalation.

2. Enforce The Use Of Strong Passwords

Enforcing the usage of strong passwords across your infrastructure is an important security measure. Attackers will have a harder time guessing passwords or cracking hashes to obtain unauthorized access to sensitive systems. A smart place to start is with 10-character passwords that include a mix of upper and lowercase letters, numbers, and special characters.

Password guessing attacks can be stopped by combining a strong password policy with a powerful account robust policy that locks accounts after a few erroneous tries.

3. Use local protection mechanisms such as firewalls and anti-virus software.

Local protection measures and estate-wide controls like patching, domain configuration, and border fire-walling are critical for offering a defense-in-depth approach.

The chance of unneeded default services being exposed to the broader network is reduced when a host’s local firewall is configured correctly. Even if your patching schedule has fallen behind, it will still prevent an attacker from accessing critical network services. While not fool proof, this all-or-nothing strategy can distinguish between compromise and attacker frustration.

With so much at stake, it’s essential to ensure your business has a robust IT audit plan. With the help of a trusted IT auditing company like Protected Harbor, you can be sure that your systems are secure and functioning at peak efficiency. Because The FBI won’t always be there, but Protected Harbor will.

Privacy Impact Assessment (PIA)

Introduction
A Privacy Impact Assessment, or PIA, determines whether or not a user’s privacy or personal information is protected. Privacy for IT systems should be addressed in addition to financial loss. Some federal agencies have IT systems and databases that store sensitive citizen data. The Privacy Act requires these agencies to adopt adequate technical, administrative, and physical safeguards to defend against cyber intrusions. The E-Government Act requires the Privacy Impact Assessment for stored information of 2002. It’s a way of evaluating the privacy of information systems and databases that are easy to use. Let’s look at the Privacy Impact Assessment (PIA).

What is Privacy Impact Assessment (PIA)

Privacy is a fit, basic human right essential for protecting human dignity. It helps people make boundaries to restrict who can access data, information, places, things, and communications. Privacy is also referred to as the right to be left alone and not disclose or publicize one’s personal information.  In Constitutional law, privacy is referred to as the right of people to make decisions concerning intimate matters. However, under the Common Law, it is about people’s right to lead their lives in a way secluded reasonably from the public scrutiny that either comes from a scrutineer eavesdropping ears or a neighbor’s prying eyes. [1][2]

Privacy Risk Assessment provides an early warning to detect privacy issues, avoid costly mistakes in privacy compliance, and increase the information available to make informed decisions. Moreover, Federal agencies are responsible for performing privacy impact assessments for government systems and programs collecting personal data under the E-Government Act of 2002. Federal agency’s CIOs ensure that the PIAs are completed and reviewed for pertinent IT systems.

The US passed a legal reform in 1970, known as the Privacy Act of 1974. It helps to make new expectations of how the federal government collects and manages information. The Privacy Act strengthened over time, and other laws with privacy concerns were added. Several best practices are established for comprehensive federal privacy programs. Leadership is essential for the success of an organization’s privacy. The selection of senior officers with privacy expertise and direct support from the organization’s head is necessary.

The responsibilities of SAOP/CPO include evaluating advanced technologies, online activities, programs, contracts, legislation, and regulations for potential privacy impacts. The formation of Privacy risk management and compliance documentation is one of the best practices recommended for ensuring the privacy of information stored by federal organizations’ IT systems. The SAOP/CPO must make and implement tools and techniques for evaluating the privacy impacts of all systems and programs. Moreover, robust security and privacy programs are vital for protecting Personally Identifiable Information (PII) used, collected, retained, shared, or disclosed by the organization. Federal organizations must implement privacy and security risk mitigation in the initial phases of the project. [3]

E-Government Act Section 208 helps government agencies to put in place enough protection for the privacy of PII. It requires organizations to perform a Privacy Impact Assessment (PIA) for IT systems to collect, maintain, or disseminate information. Moreover, the PIA procedure requires federal agencies to review the collected data, how they can use it, and develop new IT systems for handling PII collection. Implementing a PIA is necessary because it lets you ask individuals different questions and discuss best practices to implement security and privacy. A Privacy Impact Assessment is a recommended action by several authoritative sources. It satisfies legal requirements and helps agencies identify and manage risks and avoid unnecessary costs and loss of trust and reputation. [4][5]

Cities can develop a consistent method to identify, evaluate, and address privacy risks by implementing the Privacy Impact Assessment process. It helps to balance collecting data to provide services and protect citizens’ privacy, particularly while developing innovative smart city technologies. Conducting a Privacy Impact Assessment before leveraging technologies in a smart city will enhance accountability and transparency, mitigate potential harms regarding privacy, reduce legal risks, and improve compliance. Additionally, it lets people make more confident and consistent decisions about technology and data. [6]

Final Words

The elements discussed here provide a roadmap for the agencies to implement a robust privacy program. Privacy issues regarding the protection of personally identifiable information continue to be a factor for these agencies as advanced technologies and programs require usage, collection, storage, and destruction of PII keep on increasing. Therefore, the organizations must conduct PIA to identify and implement robust privacy measures effectively and quickly.

Privacy Impact Assessments are essential for protecting your data. By understanding the risks and impacts associated with data collection and use, you can mitigate potential harm to individuals and organizations. Protected Harbor is a company that specializes in privacy and cybersecurity. We can help you conduct a risk and impact assessment, and customize your infrastructure to fill any gaps.

Various ways to detect malicious activities in a network

Businesses are not reacting promptly to malicious activities. Technology is constantly and rapidly evolving and expanding the attack surface in multiple ways. At the same time, cybercriminals are adapting advanced courses and escalating the threat landscape. They are adopting sophisticated ways to attack, and the struggle to deal with the changes is real. Malicious or unauthorized activities occurring inside your network are causing damage without even you knowing that. How can you detect those malicious network activities inside your network as quickly as possible and respond efficiently to avoid or reduce the potential damage?

There are a variety of network protection tools available for this purpose. Some are enhancements or evolutions of others, and some are mainly focused on certain types of malicious activities. However, all network intrusion detection systems are intended to detect malicious or suspicious activities on your network and enable you to act promptly against them. This article will discuss these tools to see malicious activities on your network. But before that, let’s discuss the malicious activities.

What is a malicious activity?

Malicious activity is an unauthorized breach of network traffic or processes on any connected device or system. Malicious threat actors perform these suspicious activities using various attack vectors and looking for financial gain. These actors differ widely in attack techniques, sophistication, and whether they are linked to a cybercriminal group or not. There are multiple types of malicious software, and cybercriminals use many of them.  Therefore, it is essential to find out how to detect malicious activities on various platforms for different uses. Evidence of what an antagonistic activity on a network can do is everywhere.

For all organizations connected to the Internet, using it to store a company’s data or communicate with the employees, it is necessary to understand what a malicious activity can do. As digital transformation is in full rage, cybercriminals know how to use this digital shift to mold and escalate the threat landscape they create.

Malicious activities can come in various forms, particularly from an organizational point of view. It includes

• Network anomalies
• Strange network behavior
• Problem with the network traffic flow
• System downtime
• Vulnerabilities exploitation in the system
• Data breach and compromised system
• DDoS (Denial of service) attacks

There are several tools and best practices to avoid malicious activities. Let’s discuss some of them.

Network Security Tools

Here is a list of tools you can use to detect malicious activities in a network.

1. Intrusion Detection System (IDS)

An Intrusion Detection System analyzes activities on a network and vulnerabilities in a system to search for patterns and reasons for known threats. Here are two main types of IDS, Host Intrusion Detection System (HIDS) protects an individual host system, and Network Intrusion Detection System (NIDS) monitors an entire subnet at a network level. IDS raises flags for malicious or suspicious activities or any intrusion detected and sends notifications to the IT team. It does not take action to prevent or avoid that activity.

2. Intrusion Prevention System (IPS)

An Intrusion Prevention System (IPS) is an evolution of IDS. The capabilities and functions of an IPS are similar to an IDS. However, there is a difference that an IPS can take action to prevent or avoid malicious or suspicious activities. IP can also be referred to as an Intrusion Detection Prevention System (IDPS).

3. Security Incident and Event Management (SIEM)

A Security Incident and Event Management (SIEM) tool are designed to help companies manage the massive volume of data and signals and tie up threat information for a centralized view of IT infrastructure. SIEM comes in various sizes and shapes, but it is promising to monitor, analyze, and record network activities to detect potential security events or incidents in real-time and send alerts to IT teams. So they can take appropriate actions.

4. Data Loss Prevention (DLP)

Data protection is the most important thing for most organizations. It is the primary target of most cyberattacks, whether sensitive data of employees or customers, bank or credit card information, corporate data, or confidential intellectual property. Data loss prevention, also referred to as Data Leak Prevention or Data Loss Protection protects data and ensures that personal or sensitive data is secured and not exposed or compromised. DLP often enforces data handling policies based on how information is classified. In most cases, it can automatically detect things like Social Security numbers or credit card numbers depending on the data format to alert the IT team and avoid unauthorized disclosure.

5. Network Behavior Anomaly Detection (NBAD)

A simple way to identify suspicious or malicious activities is to detect a move out of the ordinary. NBAD, also termed as network detective establishes a baseline of normal activities on a network and gives real-time monitoring of activities and traffic to see unusual events, trends, or activities. Anomaly detection can identify emerging threats, such as zero-day attacks, because it looks for unusual activity instead of relying on indicators of compromise of specific threats.

Best practices to prevent malicious activities in a network

Apart from these tools, you can follow these best practices to avoid malicious network activity.

• Identify malicious emails_ Malicious actors use phishing emails to access sensitive data. It’s a growing trend in cyberspace, and employees should practice safe email protocol and must be careful while clicking on the links from unknown resources. It’s also important to have network security protection in place.
• Report a slower-than-normal network_ A malware outbreak or hacking attempt often results in a slower network. Employees should quickly inform the IT security department when they face slower than typical network speed.
• Identify suspicious pop-ups_ Increased security in a business environment means safe web browsing. Employees should not click on the pop-up windows appearing on the websites. Unknown pop-ups can be infected with spyware or malware that compromise a network.
• Note abnormal password activity_ If an employee is locked out of their system and gets an email saying that a password has been changed, it can signify that the password is compromised. The best practice is to ensure that all employees use strong and unique passwords for all accounts and update the network every six months.

Educate Yourself On Different Threats

In the realm of cybersecurity, understanding and identifying various threats is paramount. Here’s a brief primer on key threats and how to spot them:

• DDoS Attacks: These attacks flood networks with an overwhelming volume of traffic, rendering them inaccessible. Signs include sudden traffic surges, sluggish performance, and unresponsive servers. Mitigate by employing DDoS mitigation strategies and traffic analysis tools.
• Data Protection and Secure Email: Protect sensitive information with secure email protocols, encryption, and robust authentication mechanisms. Educate users on email security best practices to mitigate the risk of phishing attacks.
• Cyber Threats and Phishing: Cyber threats encompass phishing, malware, and Man-in-the-Middle (MITM) attacks. Phishing attempts to deceive users into revealing sensitive information. Types include spear phishing, whaling, and vishing. Implement robust email filtering solutions and educate users to identify phishing attempts.
• MITM Attacks (Man-in-the-Middle): In these attacks, an interceptor eavesdrops on communication between two parties, potentially manipulating data. Signs include unusual network behavior and unexpected SSL certificate warnings. Mitigate by employing strong encryption protocols, digital certificates, and intrusion detection systems.

By understanding these threats and implementing proactive security measures, you can fortify your network defenses and mitigate risks effectively. Stay informed, stay vigilant, and empower yourself with the knowledge needed to safeguard your digital assets against evolving cyber threats.

Learn To Identify Phishing Emails

Master the art of spotting phishing emails to safeguard against cyber threats and protect your data with secure email practices. Learn the red flags, from suspicious URLs to unexpected attachments, guarding against potential DDoS attacks and MITM threats. Prioritize email security to fortify your defenses, ensuring robust data protection. Stay vigilant, empower your team with awareness training, and implement encryption measures to thwart phishing attempts. By staying informed and proactive, you can mitigate risks, bolster security, and keep your organization safe from the perils of cybercrime.

Keep Your Software And Hardware Up-To-Date

Ensure Data and Privacy Protection by Keeping Your Software and Hardware Up-to-Date. Maintaining up-to-date software and hardware is paramount for safeguarding your organization’s cyber infrastructure against potential threats. Using outdated technology exposes vulnerabilities to cyber attacks exploiting known security issues. Upgraded devices offer advanced security tools, bolstering your defense against digital threats.

In addition to hardware updates, regularly patching software is equally essential. Promptly installing the latest patches ensures your team’s devices remain protected. These updates often contain critical security enhancements, thwarting hackers’ attempts to exploit software vulnerabilities.

For added data and privacy protection, consider utilizing Encrypted Email Services to safeguard sensitive information against unauthorized access.

Control Privileges and Permissions on Your Systems

One of the most effective techniques for spotting cyber threats is to control privileges and permissions on your systems. By carefully managing who has access to what resources, you can significantly reduce the risk of unauthorized activities. This approach is crucial for detecting insider threats, as it limits the ability of potentially malicious insiders to access sensitive data or systems. Implementing role-based access control (RBAC) ensures that users only have the minimum level of access necessary for their roles, thereby minimizing the risk of privilege abuse. Additionally, regular audits of permissions can help identify any unusual access patterns or unauthorized changes, aiding in the early identification of malicious activity in networks. Organizations can create a more secure environment by continuously monitoring and adjusting privileges and permissions, making it easier to spot and respond to potential threats before they escalate.

Conclusion

The threat of a cyberattack on your organization is real. Protecting your business network comes down to ensuring that security controls exist across the organization. The security tools and best practices mentioned in the article are simple and allow organizations to focus on their core business activities. It lets them take advantage of a modern world of digital business opportunities. Adequately configured network security tools are helpful for monitoring and analyzing overwhelming network traffic in a rapidly changing, dynamic environment and detecting potentially malicious activities.

Malicious activities can often go undetected in a network because they are disguised as regular traffic. By properly configuring your security tools, you can monitor and analyze network traffic to detect any activities that may be malicious.
