Hacker challenge sites, A list of hacker challenge sites

Hackthissite - www.hackthissite.org
A nice site (even though it has been having problems recently) including basic web challenges, "realistic" missions, basic cracking and encryption challenges.

ngsec - www.ngsec.com
A great website, with some tough final challenges. Including SQL Injection and some Buffer overflow challenges.

Try2Hack - - www.try2hack.nl
One of the most well known hacking challenge sites, its levels are basic and ideal for those new to security.

Hackerslab - www.hackerslab.org
A great site with levels based around unix security, you'll either want to use linux or have a copy of putty to complete any of these challenges.

SlyFX - www.slyfx.com
A great challenge site, starts off with some basic maths and moves onto solving application problems (starts with some basic debugging and moves onto solving stuff)

Mod-X - www.mod-x.co.uk
Never completed this site, got a little bored with it. But on the whole rather good, if you've played the game uplink it's that sort of story (i think, as I said, never really played it I got bored at lvl3 )

HackMe @ Elderson - hackme.elderson.net
Only a few challenges, but they are interesting ones.

Hope that this wil help our hacking curious members . Also the site admins.

One more suggestion is that what if we make a VPN in which one can hack other member's computer in realtime. Since it's VPN i guess no legle stuff is required (that is what i guess!!!)

I will be posting the others as i will get..

i had put this thread in here instead of the last section of forum cuse i had seen more people visiting this section then that one

Any comments will be highly appriciated and your contribution to this archive too.

I moved this post from "Windows & DOS to here, since this is not a technical question but something to share with users of Firewall.
