KillDisk Malware Turns into Ransomware: Technical Details

Previous versions of KillDisk were designed to wipe hard drives so that the targeted system is inoperable. The new iteration of the malware was analyzed by industrial cybersecurity firm CyberX. The researchers discovered that the malware-turned-ransomware is using a combination of RSA and AES algorithms.

KillDisk Encryption Process

Each targeted file encrypted via an individual AES key and then all the keys are encrypted using the RSA 1028 key, which is stored in the body of the malware. Basically, researchers were able to conclude that the KillDisk ransomware, or crypto malware, is quite sophisticated and well-written. The newly detected variant shares a lot with the previously detected KillDisk pieces.

What Data Does KillDisk Ransomware Target?

The crypto malware is able to encrypt a range of files, such as documents, databases, source code, disk images, emails, and media files. In addition, both local partitions and network folders are targeted successfully.

The amount of the ransom is 222 Bitcoin which amounts to $210,000. This alone proves that the ransomware operators will be targeting organizations with great financial resources. The email address provided to affected users is connected to Lelantos, a secure, anonymous email provider available through Tor. As for the Bitcoin address provided for payments, no transactions have been detected there.
