Applies to

  • ONTAP 9.11 and above
  • Autonomous Ransomware Protection (ARP)

Issue

  • ARP enabled on volume
  • ARP suspected ransomware files continue appearing even though they were marked as false positive in System Manager and/or using the command:
  • CLI：security anti-ransomware volume attack clear-suspect -vserver <svm> -volume <volume> -false-positive true
  • GUI：Abnormal volume activity detected on <date>     suspected ransomware files
  • This seems to be related to new\unknown extensions since each file extension reported is different.

  • in security anti-ransomware volume attack-detection-parameters show, the never-seen-before is set to true
