When time is of the essence and next steps are uncertain, organizations should consult with the experienced professionals at Ontrack to determine their best course of action.

Ransomware Case Studies

Ontrack delivers world-class data recovery for all types of storage including: hard drives, solid-state drives (SSD), servers, NAS, SAN, virtual machines, cloud, mobile devices and tape.

CryptoLocker Ransomware

A single user’s laptop at a large pharmaceutical company was infected with CryptoLocker ransomware. The laptop was connected to the corporate network, which allowed the malware to infect 46 shares. Leveraging NetApp’s proprietary OS (OnTap) and file system (WAFL), Ontrack engineers used multiple consistency points to “walk back” in time to a point before the attack to find and recover unencrypted copies of the critical data to return to the client.

Erased Backups

Ransomware attacked a company server, encrypted the Microsoft Dynamics 365 data, and demanded payment. Recent backups of the server were stored on multiple LTO-6 backup tapes, which had been erased by the malware. Working in conjunction with the R&D department, Ontrack developed a custom hardware and software-based solution to recover 46TB of data from 18 of the LTO-6 erased backup tapes.

Healthcare Ransomware Attack - Veeam Agent for Windows

A health care customer was affected by a ransomware attack that not only targeted their server data, but also “Veeam Agent for Windows” backups located on an external HDD. Their IT / managed services provider agreement did not include regular off-site backups, so this was the only copy of the data that existed.

Phishing Attack

A multinational chemical corporation experienced a ransomware attack that took over a server using administrator privileges obtained through phishing. The ransomware formatted all the hard drives and created a new aggregate. Ontrack was able to rebuild the RAID and the original volumes, and restore the client's data.

Current Ransomware Trends


The number of attacks is down, but the severity, size and payments for each attack are up​.


Only 50% of the victims that pay the ransom are able to decrypt all of their critical files.


Attacks are targeting file shares, critical infrastructure and backups including cloud​.


Cyber Insurance is paying a significant number of claims including data recovery​.
