Test your hacking skills

While visiting the hacker community on orkut i came across a thread about a site which offered you to hack through it . There are many levels involved each one more difficult than the previous.

Here is the url http://www.loginmatrix.com/hackme

This is a really good game , all those having an IT background should try it :)

P.S You should have a knowlegde of JavaScript , I personally managed to arrive on level 5 where I am currently trying to hack.
