Root This Box is a live hacking challenge where users can practice their attack and defence skills on machines set up for free range hacking. People form teams with other users and compete against other teams for control over these machines. When a machine is taken over, the team can put up a message and try to defend the machine against other attacking teams.
I wanted to know if anybody wanted to play this with me. Its not a game, its actually hacking, so if you think your up to the challenge, then post a reply below.
