What can an attacker do with SeDebugPrivilege to escalate privileges or access sensitive processes?

SeDebugPrivilege allows a user to debug any process, including those running as SYSTEM, effectively granting the ability to read and write process memory. An attacker with this privilege can inject code into SYSTEM processes, steal tokens, or dump credentials. This is one of the nine exploitable privileges outlined in Penetration Techniques - Exploitation of Nine Windows Privileges, and it is often combined with techniques like Penetration Techniques - Token Theft and Exploitation.
