This was a set of bonus points awarded to Neg9 for finding another team's RSA private key stored in their world readable home folder on the community jump box.  Neg9 connected as the team, and spammed the wall about how this account was own3d.  Then changed permissions and moved the private key to a more appropriate .ssh folder with 0600 permissions.
