Malware Warning

  • 1.  Malware Warning

    New customer of ours had a malware attack. They had a NetServer guest profile and a root directory share. Their only saving grace was the guest profile didn't have *ALLOBJ. Anything that wasn't nailed down got encrypted. We're closing those doors now. And more.

    They dodged a howitzer. Keep yourself protected.  https://www.itechsol.com/the-real-effects-of-malware-on-ibm-i/

    Ouch, this is bad. 
    Is it "just" to restore from backup or is the backups encrypted as well or some malware that just starts encrypting it again after restore?

    It's a recovery and IFS hardening. It used the guest user ID and the root share to do the damage. Once those doors are shut they're most definitely in better shape than before. Far less risk.

    Thank you very much for the timely warning Steve.

    It's a great reminder that incorrectly set IFS permissions and broad scope shared folders via NetServer are still a risk that most people overlook, or fail to audit on a regular basis.
