Ransomware is a type of malware that restricts access to infected computers and demands that the user make a payment to the malware operators to remove the restriction.
Commvault detects the presence of Ransomware malware on your client computer.
Commvault notifies the CommCell Console administrator immediately by displaying the following event message: Detected a possible Ransomware attack. Please verify the data on the machine.
This message helps you to investigate the attack on the affected computer and prevents long term damage. The predefined Ransomware alert is configured, and it sends an email to the administrator when ransomware is detected. To remove infected files from the network, you can trigger a workflow based on the Ransomware alert.
