Abstract:
The present disclosure describes systems and methods for detection and mitigation of malicious activity regarding user data by a network backup system. In a first aspect, a backup system receiving and deduplicating backup data from a plurality of computing devices may detect, based on changes in uniqueness or shared rates for files, atypical modifications to common files, and may take steps to mitigate any potential attack by maintaining versions of the common files prior to the modifications or locking backup snapshots. In a second aspect, the backup system may monitor file modification behaviors on a single device, relative to practices of an aggregated plurality of devices. Upon detection of potentially malicious modification activity, a previously backed up or synchronized store of data may be locked and/or duplicated, preventing any of the malicious modifications from being transferred to the backup system.

Claim (Index 15):
A system comprising:\n a backup system in communication with multiple computing devices, wherein the backup system detects legitimate file activity occurring on the multiple computing devices, wherein the legitimate file activity comprises modifying a file and sharing a file, and wherein the backup system calculates at least one file activity threshold based on patterns of the legitimate file activity occurring over time on different ones of the multiple computing devices; and a backup agent in communication with the backup system, wherein the backup agent detects a plurality of client file activities occurring over time on a client device of the multiple computing devices, and wherein the backup agent prevents modification of previously backed up data of the client device responsive to the client file activities exceeding the file activity threshold.
