: The EDR inspects the request and blocks it if it looks like malware. The Trick: UnhookingKnownDlls.exe
: When a program tries to perform a suspicious action (like encrypting files), the EDR’s "hook" intercepts the call. UnhookingKnownDlls.exe
For IT professionals and security researchers, seeing a file like UnhookingKnownDlls.exe is a major red flag. : The EDR inspects the request and blocks
: It is a core component of "evasion" techniques used by advanced persistent threats (APTs). : It is a core component of "evasion"
: An attacker uses an "unhooker" to map a fresh copy of a DLL directly from the disk into the program's memory.
: High-end security software now monitors for the act of unhooking itself, turning the attacker’s own evasion tool into a beacon for detection.
Tools like this work by restoring these hooked DLLs to their original, "clean" state. This effectively blinds the security software.
