Great article on API hooking!

As I was browsing RE related blogs and articles I stumbled upon this gem.

Amazing article that gave me more insight on how to perform more stealthy hooking.

Success, defeated the antidebug of Crysis 3.

Well after a month I finally made progress. Turns out the error code 2001 I was getting was caused by GetTickCount returning 0 or a unreasonable value. After fixing this I got an error code value of 8011, then I patched the ProcessDebugFlags check(0x1f on NtQueryProcessInformation) and the game now runs under a debugger.

Obviously this is good news, but far from the expected result. Where is the VM? What does it do? What kind of anti-dumping techniques are used? Many more questions to be answered.
