All your need to know about Privilege Escalation Detection

Organizations' vulnerability to cyberattacks grows as they rely more on remote working abilities EDR and larger cloud systems. Privilege escalation attacks are a common and escalated danger that can affect any network. When any asset can become an entry point for intruders, organizations require multiple defense strategies. One of the most important first steps in preventing and protecting against significant network attacks is to understand the privilege escalation procedure.

Privilege Escalation Detection

A cyberattack known as a privilege escalation attempt seeks to acquire unauthorized access to privileged systems. Attackers take advantage of human behaviors, weaknesses in design, or oversights in operating systems or web applications. This is closely related to lateral movement, which is a cyber attacker's method of moving further into a network in search of high-value assets.

As a result, an internal or external use with unauthorized system privileges is created. Bad actors might cause minor or substantial damage depending on the scope of the breach. This could be as basic as an unauthorized email or as complex as a ransomware attack on massive amounts of data. Attacks that go unnoticed can lead to in advanced persistent threats (APTs) to the systems.

How Do Privilege Escalation Detection Attacks Work?

Usually, privilege escalation attacks prey on flaws like faulty access controls, software defects, and configuration errors. Any account that interacts with a system has some level of authority EDR. Standard users have restricted access to system databases, sensitive files, and other resources. In some circumstances, people have unauthorized access to important resources and may be unaware of them since they do not seek access beyond their entitlements. In other circumstances, attackers can exploit system flaws to gain increased privileges.

A hostile attacker gains access to a sensitive system by taking over a low-level user account and either abusing or raising privileges. Attackers may spend some time in a system undertaking reconnaissance and waiting for an opportunity to broaden their access. They will eventually find an opportunity for privilege escalation to a higher level than the compromised account. Depending on their goal, attackers can continue to take control of new systems horizontally or privilege escalation vertically to obtain admin and root control until they have access to the entire environment.

Examples of Privilege Escalation Detection Attacks

Malware, such as the following, is typically used in privilege escalation attacks to infect a network or application.


Self-contained programs reproduce and replicate and distribute copies to other computers.


Software collections are designed to offer actors control of a network or application. Once triggered, they open a backdoor to propagate further malware, which can remain undetected for years.


Malware in the form of legitimate software is intended to deceive users via social engineering techniques like phishing or bait websites.

Fileless malwares

Unlike typical malware, this does not necessitate the installation of malicious code on a target's machine, making it difficult to detect.


Surveillance software that tracks users' web activities without their knowledge or consent. (Adware is a sort of spyware that monitors a user's internet activities to determine which advertisements to display to them.)


Spyware that tracks user activities and is often distributed via phishing. Keyloggers, once installed, can steal passwords, user IDs, banking information, and other sensitive information.


Programs (often pop-up alerts) mislead users into believing their machine is infected, enticing them to install bogus antivirus software that is actually malware.


When an adversary encrypts a victim's data and provides a decryption key in exchange for payment, attackers can use social engineering techniques or unpatched vulnerabilities and policy misconfigurations to launch these attacks.

Importance of Preventing Privilege Escalation Detection Attacks

Privilege escalation is a means to an end for attackers. It enables them to acquire access to an environment, maintain and enhance their access, and engage in more serious harmful attacks. Privilege escalation, for example, can turn a simple malware infection into a catastrophic data breach. Attackers can use privilege escalation to open up additional attack avenues on a target system. It could, for example, include:

  • Gaining access to additional systems that are linked
  • Adding more malicious payloads to a target system
  • Changing security options or privileges
  • Obtaining access to apps or data on a system that exceeds the privileges of the compromised account
  • Obtaining root access to a target system or an entire network in extreme cases.

When security teams suspect privilege escalation, it is crucial to conduct a thorough investigation. Malware on sensitive systems, odd logins, and unexpected network communications are all signs of privilege escalation.

Depending on the organization's compliance standards, each privilege escalation incident is required to be worked as a severe security incident and may even need to be reported to the authorities.

Conclusion - How Xcitium can help?

Privilege escalation is an effective way for getting greater access control within systems. Attackers without privilege escalation will probably be regarded as common users with limited access and the capacity to conduct their attacks. Xcitium Cybersecurity continuously observes and profiles user activity to build a genuine behavioral baseline and detects anonymous activity that shows user account compromise or privilege escalation.

FAQ section

A: Some of the major signs which help with privilege escalation detection include suspicious logins, malware detection on systems, and unusual network communication.

A: Some of the major impacts of privilege escalation are for an attack to gain admin user privileges which could help them to attack various sensitive infrastructures which and modify permissions, add or delete users or insert malicious codes.

A: Privilege escalation is a vulnerability where the attackers access the user through added privileges. This is caused because of a flawed system and other weaknesses that attacker uses to their benefit.

A: Privilege escalation can be categorized into main types, namely horizontal and vertical. This is a major vulnerability that helps attacks to gain additional privileges which were not added to the original user.
