Lateral Privilege Escalation

A lateral privilege escalation is a cyberattack technique where an attacker moves from one compromised account to another account with similar or different privileges within the same network.

Unlike vertical privilege escalation, which involves gaining higher-level access (such as moving from user to administrator), lateral movement focuses on expanding access across systems, users, or resources at comparable privilege levels.

Attackers typically employ lateral privilege escalation after gaining initial access to a network through methods like phishing, malware, or credential theft. Once inside, they use techniques such as credential harvesting, pass-the-hash attacks, or exploiting trust relationships between systems to compromise additional accounts. This allows them to explore the network, gather sensitive information, and establish multiple footholds that make detection and removal more difficult.

Common tools used in lateral privilege escalation include PowerShell Empire, Cobalt Strike, and Mimikatz, which can extract credentials from memory or exploit Windows authentication protocols. Organizations can defend against these attacks through network segmentation, implementing the principle of least privilege, monitoring for unusual lateral movement patterns, and using advanced threat detection systems that can identify suspicious account-to-account activity across the network infrastructure.
