Ransomware hidden in backups requires organizations to re-examine strategies

In response to developing ransomware techniques which target backups, Asigra is calling for organizations to review their backup policies and double down on redundancy so that multiple remote copies of mission critical backups are available when the next attack occurs.

Data protection specialists agree that the number one strategy for recovering data lost to criminal encryption is through a reliable data recovery strategy. However, with ransomware variants now targeting backup data, organizations must take extra steps to ensure their backup data is clean before conducting a recovery.

Ransomware infected backups have resulted in a recovery attack-loop that re-introduces time-delayed, undetected ransomware onto the network from the backup data. This has negatively impacted recovery for many organizations as it renders the recovery of encrypted files useless, allowing the malware to re-constitute and re-encrypt the primary data again. Therefore, defending recovery data from such attacks using a redundant backup strategy is key as is the deployment of an evolved data protection solution that offers a robust recovery framework.

Regardless of the backup platform used, a redundant data protection strategy should be employed to ensure an effective recovery. This approach requires that multiple copies of the company’s mission critical data are created. These backup sets should be stored on multiple media formats, such as secondary disk storage or the cloud with at least one of the backup data sets stored in an offsite location. Once in place, data policies should also be enhanced to include more regular test recoveries to determine the effectiveness, quality and speed of the recovery.
