Hacking Game that I Played

I think, these are sites where I learned some basic hacking and cracking techniques.

Hellbound Hackers (HBH)
Netforce
Hackits.de
Zero-Identity
Dareyourmind
HackThisSite (HTS)
Chumley.biz
Bright-shadows.net

You can find my username in those sites, except HBH, i use viperfx instead.

And there is one site from Indonesia, although it's like HackThisSite.org for some challenges.
