Thebackupbox is back, with a few changes to mention.
The ports forwarded to the external interface are ports 80 and 24 (ssh). Unlike it's previous iterations, the IRC server isn't going to be hosted on the same machine. In case IRC access is needed, connect to DarkScience.

To play the levels, ssh -p 24 user@hack.thebackupbox.net.
level0's password is h4x0r3d.

SSH keys have been replaced. New SSH fingerprints:
d5:48:6f:5c:db:22:00:87:f6:ac:db:86:f7:31:15:95 - RSA
ff:d6:80:f9:69:fb:71:c2:83:94:f2:10:91:99:5a:c9 - DSA
