Team neg9 discovered that another team had uploaded their private RSA key to the shared jumpbox, and set the permissions world-readable.

They then used this key to log in to the other team's account, and post amusing messages on 'wall'. They also corrected the other team's permissions, so that no other teams could follow in their footsteps, and informed the contest organizers.

For hacking a fellow team, and pranking in the spirit of OpenCTF, neg9 was awarded 11 discretionary bonus points.
