Windows Protected Process Light (PPL): Attack Vectors and Bypassing Protection Mechanisms

The article focuses on the Protected Process Light mechanism in Windows, which provides isolation of critical system processes from access, injection, and memory dumping even by highly privileged users.

It also describes an attack chain combining BYOVD (Bring Your Own Vulnerable Driver) and abuse of PPL, enabling attackers to bypass protection restrictions. In addition, it examines attack surfaces related to memory dumping, as well as detection and monitoring blind spots across different levels of PPL where Windows protection mechanisms prove to be less effective.
