However, requesting a password change alone does not always resolve the incident because the method of obtaining the credentials in the first place may involve other attack vectors, like malware or a compromised cell phone. If the threat actor is detected, an organization typically resets passwords as a high a priority and reimages infected systems to mitigate the threat (especially if it involves servers). Once a threat actor has compromised credentials, everything privileged to that account is now fair game for the attacker. With a sysadminвЂ™s credentials and access, a cybercriminal can move laterally, while arousing little or no suspicion. Often, a threat actor will first target a systems administrator since their credentials frequently have privileges to directly access sensitive data and systems. However, if a threat actor knows the username, obtaining the accountвЂ™s password becomes a hacking exercise. Valid single factor credentials (username and password) will allow a typical user to authenticate against a resource. LetвЂ™s now look at five major classes of privilege escalation attacks.

If this is the case, a threat actor is further along in their malicious plans and may already own an environment.ДҐ Common Privileged Escalation Attack Methods Of course, itвЂ™s possible the initial compromise involved an administrative or root account. Typically, the second step in the cyberattack chain involves privilege escalation to accounts with administrative, root, or higher privileged rights than the account initially compromised. Once an organization identifies an intrusion, they may monitor the intruderвЂ™s intentions, and/or potentially pause or terminate the access session.

Whether this involves masking their source IP address or deleting logs based on the credentials they are using, any evidence about their presence reflect an indicator of compromise (IoC). If time permits, they will clean up their activities to remain undetected. Threat actors will customarily pursue the path of least resistance. Once the initial infiltration has been successful, threat actors will typically perform surveillance and wait for the right opportunity to continue their mission. An attacker could gain this beachhead by leveraging missing security patches, social engineering, or many other methods. Threat actors start infiltration by gaining a foothold within the environment. In 2020, elevation of privilege vulnerabilities comprised 44% of all Microsoft vulnerabilities, according to the Microsoft Vulnerabilities Report 2021. execute a buffer overflow attack, etc.) to bypass or override privilege controls, or exploit flaws in software, firmware, the kernel, or obtain privileged credentials for other applications or the operating system itself. Achieving vertical privilege escalation could require the attacker to perform a number of intermediary steps (i.e. This entails moving from a low-level of privileged access, to a higher amount of privileged access.

Vertical privilege escalation, also known as a privilege elevation attack, involves an increase of privileges/privileged access beyond what a user, application, or other asset already has.

With each new horizontal account compromised, an attacker broadens their sphere of access with similar privileges. standard user), which may lack proper protection. This action is referred to as вЂњaccount takeover.вЂќ Typically, this would involve lower-level accounts (i.e.

Horizontal privilege escalation involves gaining access to the rights of another account-human or machine-with similar privileges.

Often confused with each other, these terms are can be differentiated as follows: Privilege escalation attacks can be separated into two broad categories-horizontal privilege escalation and vertical privilege escalation. Vertical vs Horizontal Privilege Escalation
