There is an ongoing attack against academic HPC centers in Europe right now, and several clusters and storage systems have been compromised. The attackers have used stolen credentials (passwords and/or SSH keys) to get into systems. We are investigating whether any of our systems are affected. In the mean time we encourage everyone to create new SSH keys. See for a description of how to create SSH keys. Please do set a passphrase on the keys, so they will be worthless if they should be stolen. Please also remember to remove old SSH keys from your ~/.ssh/authorized_keys file on each system (NIRD, Fram, Saga, Stallo, Vilje), so noone can use the old keys any more.
