Doubtful, it looks like it's just replacing the game executable, probably with a decoded version. It needs analysis of what stub.dll is doing.
AFAIK it's a solution from cheaters, original seems to come from http://gamingonsteroids.com/topic/27400-813temporary-hotfix-for-new-antichea.... Seems like a cheaters site to me. Pretty ironic that legit players can't play, but cheaters already cracked it. But I would NOT use that if you don't want your account banned!
