Serverfile and backdoors

[Dafuq313 2]

Has anyone tested this sf yet ? I see there are a lot of commentaries and I can't find someone to say something about bugs or backdoor

Also,how i can search a source for backdoor ? With example would be perfect.

1. there's no developer that uses other files that those made on his own.

2. You need to know C++ on advanced level, you have to know how memory, processor, databases etc works. One bd might use memory to initialize itself, the other one might use DB etc etc.
