I tested ScyllaHide on Windows XP and Windows 7 32bit. Everything works fine.
ScyllaHide on Win 7 64bit doesn't work
Obsidium is really an anti-debug hell. It uses this:
OutputDebugStringA
Illegal Instruction Exception
EnumWindows
NtQuerySystemInformation
NtQueryInformationProcess
NtClose
PEB
OutputDebugStringA is one of the last checks... something is missing on windows x64....
Somebody has any idea?
