Checking if an API is monitored (hooked?) (1 answer)

Closed 9 years ago.

Can anyone tell me how to check for inline function hooking? I installed the famous root-kit Hacker Defender. It uses inline function hooking technique. But when I check 5 first bytes of the function in Windows API, I can't see op-code for jump instruction. How can I detect whether or not a function is hooked? Thanks.

Answer 1

Rootkit Unhooker can detect inline hooking.

GMER also does that according to its specifications.
