Hey, guys! I just logged into the U.S. Government's network with malicious intentions! I'm totally not hacking, right?
Actually no, you're cracking, not hacking.
Hacking is fiddling with programs with no malicious intent, merely for curiosity's sake and to see if you can add to or improve something's function.
Cracking is what most people consider hacking.
So no, you're not hacking, you're cracking.
