GREEN = fully operational YELLOW = operational with restrictions (see messages below) RED = not available

Passwords will be invalidated for all Linux Cluster and SuperMUC Users

May 22, 15:00

Please reset via https://idmportal.lrz.de/pwreset/ or IDM-Portal

Because we cannot discount the possibility that the perpetraors have gained knowledge about other users' passwords and secure
shell key pairs, the following measures will be executed by us on short order:

  1. The SIM password of all user accounts with access permission to an HPC system at LRZ (Linux-Cluster, SuperMUC-NG,
    Cluster-Housing) will be invalidated on May 22, 15:00. All these users must reset their passwords via 
    https://idmportal.lrz.de/pwreset/.
  2. All secure shell keys of regular users stored on the system will be made invalid and therefore cannot be used for
    authentication any more. All users therefore will need to generate new key pairs; we point out that it is essential that
    the private key used for authentication from the users' workstation must not be configured with an empty pass phrase.

Furthermore, all users of the cluster systems are obliged to add key-specific "from" clauses to all their entries in
~/.ssh/authorized_keys, in order to limit access to the actually needed external systems. We will appropriately update the
secure shell documentation before user operation is resumed on our systems.
