The Unusual File Activity report for Security IQ dashboard displays information about anomalous file systems activity of the protected file system server, or the protected endpoint servers. You can view file path information for the anomalies and track anomaly trending information. This report helps in identifying and acting on potential threats with quick and safe recovery options.
Unusual file activity occurs when a large number of files are created, deleted, modified, or renamed on a client computer, or when the number of created, modified, or deleted files in a backup job suddenly increases or decreases. These situations might indicate the presence of ransomware or other unauthorized changes to the file system data.
The Unusual file activity panel also displays anomalies in the file types of backed up files on Windows clients computers. The anomaly is displayed when there is a mismatch in the file type of the file and the file extension.
The anomaly thresholds are based on historical activity and machine-learning algorithms to reduce false positives from typical activity on the file systems. These activities are monitored by default. To receive alerts when abnormal activities are detected, in Alerts, configure the File Activity Anomaly Alert.
Note: The file anomalies that are older than 30 days are pruned automatically.
