Yuri Slobodyanyuk on Reversing

The channel shows how to do things which you cannot otherwise find on Google. 
The topics are network and application security in general, and reverse engineering binary files and protocols, crack proofing the software, analyzing undocumented network and operating systems  features in particular.
The best way to watch videos is via Playlists. Also pay attention to the language in the header (English if not stated explicitly), as I speak quite a bit of languages and will post stuff accordingly voiced in some of them.
Thanks for dropping by and enjoy.
