Ranzy Ransomware: Better Encryption Among New Features of ThunderX Derivative

Ranzy ransomware emerged in September/October this year, and appears to be an evolution of ThunderX and, to a lesser extent, Ako ransomware. Ranzy shares many features and under-the-hood elements with its predecessors.

However there have been a few key updates, including tweaks to encryption, methods of exfiltration, and the (now commonplace) use of a public “leak blog” to post victim data for those who do not comply with the ransom demand.
