About this tag
The tag ppl on WindowsForum.com covers two distinct topics: Protected Process Light (PPL) security policies in Windows and the Parallel Patterns Library (PPL) for asynchronous C++ programming. In security discussions, PPL refers to a Windows mechanism that enforces signature checks on protected processes, which can be abused in boot-time evasion techniques against antivirus and EDR agents on Windows 11 25H2. In developer contexts, PPL denotes the C++ library used to simplify asynchronous programming in Windows 8 Metro style apps, integrating with the Windows Runtime APIs. Both uses are relevant to Windows system internals and development.

    EDRStartupHinder: Boot Time Bindlink Evasion on Windows 11 25H2

    A newly published proof‑of‑concept (PoC) called EDRStartupHinder demonstrates a local, pre‑boot startup technique that can prevent antivirus and EDR agents from initializing on Windows 11 25H2 by abusing the platform’s Bindlink API and the interaction between DLL loading and Protected Process...
