Hacking a phone, a server, a Database or a computer does not depend on programming language, but exploit the existing vulnerabilities. If you mean by create Windows virus/trojan/malware, them are generally written in Visual C++ (VC++), and you can learn it by buying books for basic knowledge and go to practice. so i think adrian lamo uses c plus or v plus for hacking.
I don't know why every one talk about Nicholas Shields, I'm not the only Hacker online, but if you like to know what hackers use i can tell you , to hacking web site for example you need script python or Perl or ruby ... but its not the important part because first you should know what you will do and then it will be easy because maybe you will found some code in the internet like here Exploits Database by Offensive Security , so there is a different between someone who hack by using tools and code already done and someone who found "zero days" bugs and expel hacking.
