Respond to a detected ransomware alert

If BlueXP ransomware protection detects a possible attack, an alert appears on the BlueXP ransomware protection Dashboard and in the BlueXP Notifications in the upper right indicating a potential ransomware attack. The service also immediately initiates taking a Snapshot copy. At this point, you should look at the potential risk in the BlueXP ransomware protection Alerts tab.

To begin to recover your data, mark the alert as ready for recovery so that your storage administrator can begin the recovery process.

Each alert could have multiple incidents on different volumes with different statuses, so be sure to look at all incidents.

The service provides information called evidence about what caused the alert to be issued, such as the following:

  • File extensions were created or changed

  • File creation occurred and increased by a listed percentage

  • File deletion occurred and increased by a listed percentage

An alert is based on the following types of behavior:

  • Potential attack: An alert occurs when Autonomous Ransomware Protection detects a new extension and the occurrence is repeated more than 20 times in the last 24 hours (default behavior).

  • Warning: A warning occurs based on the following behaviors:

    • Detection of a new extension has not been identified before and the same behavior does not repeat enough times to declare it as an attack.

    • High entropy is observed.

    • File read/write/rename/delete operations incurred a 100% surge in activity beyond the baseline.

Evidence is based on information from Autonomous Ransomware Protection in ONTAP. For details, refer to Autonomous Ransomware Protection overview.
