True.
I know some C/C++ (the most complex thing I did was a keylogger that sent data through FTP, by injecting a DLL into web browsers so the firewall wouldn't complain), Delphi, Php, Matlab and assembly (knowing assembly is the easiest part, the toughest part is programming with it
). I only learned to make what I needed though, so my knowledge is somewhat restricted.
Reverse engineering is interesting, something I need to get better at.
Yea, and useful too
