New GhostLocker Tool that Uses Windows AppLocker to Neutralize and Control EDR

GhostLocker is a publicly released research tool that automates deploying AppLocker deny policies to prevent EDR userland components from launching or restarting, rendering modern EDR solutions ineffective after a reboot by blinding their user-mode analysis engines while kernel drivers remain loaded. The report demonstrates complete neutralization in tests, contrasts this approach with kernel-level WDAC protections, and recommends monitoring AppLocker policy changes and using APIs to pre-validate security product execution.
