A proof-of-concept demonstrates a patchless bypass of ETW and AMSI using hardware breakpoints and vectored exception handling, reverse-engineered from the Turla Kazuar v3 loader. The technique avoids modifying code in memory, making it stealthier against EDR memory integrity checks. It was tested on Windows 10 22H2.

Researchers demonstrated a proof-of-concept AMSI bypass using reflection techniques that successfully evaded modern antivirus and EDR solutions. The method manipulates the AMSI runtime to disable script content scanning, allowing malicious code execution. The bypass is expected to remain effective until Microsoft implements deeper reflection monitoring.
