Kroll Ontrack is assisted by NetApp’s technology to solve a ransomware infection.

A single user’s laptop at a large pharmaceutical company was infected with CryptoLocker ransomware. This malware encrypts the user’s files and withholds the encryption key until you pay the ransom amount. The laptop was connected to the corporate network which allowed the malware to infect a CIFS volume which was set up as a file share on a NetApp FAS. The malware was able to infiltrate the file share and encrypt the majority of the files. The IT team was not notified of the infection until after the backup retention period had expired, meaning that the backup contained only encrypted data. The 46 affected drives were brought to Kroll Ontrack for data recovery.
