Data recovery for corrupted or infected backup systems

The recent increase in ransomware cases targeting backup files means that organisations who suffer a malware attack can no longer rely on backups to restore important data from critical systems.

We have developed specialist software that allows us to restore critical data files from ransomware infected backup systems, such as Veeam that would otherwise be permanently irretrievable.

We’ve had multiple successful recoveries of malware-infected data when the customer had believed they were out of options.

Any device, any situation

Case study: Malware-infected Veeam recovery

With over 35 years of experience, our global team of engineers can successfully recover data from Veeam VBK files.

In this case study, a ransomware attack left a large corporate IT system crippled. Our engineers were able to overcome the odds and recover the client’s critical data, avoiding a large ransom payment.

"A large German company suffered a cyber attack that left 100 servers partially encrypted. The ransom demanded by the hacker was over 400,000€. Federal police were unable to identify the ransomware type but determined that it has been designed specifically to target the organisation. 

The customer had a SAN with 50 drives. After forensic analysis it was found that all the data inside the LUNs had either been deleted or overwritten. The attack affected six LUNs, each 25TB in size, with different file systems – four ReFS and two NTFS. 

Ontrack’s engineers managed to repair the logical damage, allowing the recovery of every file in the four ReFS systems. The Ontrack team then created a custom tool that allowed them to piece together the NTFS file system and duplicate the database, so that the data from a Veeam backup could be extracted and delivered to the customer."
