FireWalker Instructions
This repo contains a simple library which can be used to add FireWalker hook bypass capabilities to existing code; the FireWalker concept is described on the MDSec blog at https://www.mdsec.co.uk/2020/08/firewalker-a-new-approach-to-generically-bypass-user-space-edr-hooking/.
To use the library just #include
the FireWalker.h source file within existing C++ code and wrap API calls which may be hooked with FIREWALK
, e.g.:
if (!FIREWALK(QueueUserAPC((PAPCFUNC)lpvRemote, hRemoteThread, NULL)))
{
printf("QueueUserAPC failed\n");
return 1;
}
At present FireWalker only supports 32-bit code with 32-bit hooks; x64 and WoW64 support may be added if the concept is popular.
