How can you hack your girlfriends webcam?

Answer 1

1,000,000+ lines of code. Hacking is very, very, very hard. It's not at all like the movies, where you just type some thing like "hack <nameofcomputer> trojan.exe". In real life, you first need to penetrate the firewall, then gain admin control, either by tricking the user into giving your program admin control, or backdoor programs. Both are extremely difficult, because on one you have to fake a certificate, and on the other, you have to find a loophole left in the programming, which both apple and microsoft are very good at covering.
