No idea how there's even a question about this being detected or not. The only thing I've seen in this thread is 1000 detected claims opposing to the creator claiming it to be undetected.
Use it if you feel like highly risking your account - like even more than with the other public hacks contributed by this forum.
If you really want to make a vac undetected hack, you'll need to look at mapping your code into running processes without changing their signature or other specifics. As well as not having your code run in a seperate thread, therefore making it's functions get called by the 'target process' you're changing.
Either that, or you "fully" reverse vac and build your hack to replace it.
Both take immense time and a fair share of coding knowledge, therefore I doubt either are given out as public.
If you hack, you must be consent with getting banned. If you'd still like your account last long, look at hacks that have gone undetected for long, or those coded by well known programmers with positive feedback.
Honestly, neither is the case here (no offense), so either don't use this or expect to be banned within a few days.
