About this tag
EDR evasion techniques discussed on WindowsForum include kernel-level security tampering, boot-time bindlink abuse, and AI-assisted development of evasion frameworks. Threads cover real-world attacks using Exchange web shells, RMM tools, and ransomware, as well as proof-of-concept tools like EDRStartupHinder and EDR-Redir V2 that exploit Windows Bind Link and cloud filter APIs to redirect EDR folders or prevent security agents from loading. The content also highlights threat actors using AI tools like Cursor and Claude to accelerate EDR-evasion testing. These discussions are relevant for Windows administrators and security teams focused on detection, hardening, and understanding evolving evasion methods.
