I can't really say I'm surprised you got hacked. Running stuff like "chmod -R 777" over system directories? Running non-admin tasks as root? If it's any consolation, you're not the only one. I see many people doing this sort of thing all the time.

Oh, and then there's also this little Chromium 0-day:

It's generally not a good idea to run unsupported software, but if you you've got to do it, at least try to avoid running things that would tell a hacker, "Hi, come and get me!"
