New Luna ransomware encrypts Windows, Linux, and ESXi systems

A new ransomware family dubbed Luna can be used to encrypt devices running several operating systems, including Windows, Linux, and ESXi systems.

Discovered by Kaspersky security researchers via a dark web ransomware forum ad spotted by the company’s Darknet Threat Intelligence active monitoring system, Luna ransomware appears to be specifically tailored to be used only by Russian-speaking threat actors.

The group behind this new ransomware developed this new strain in Rust and took advantage of its platform-agnostic nature to port it to multiple platforms with very few changes to the source code.

Using a cross-platform language also enables Luna ransomware to evade automated static code analysis attempts.

Luna further confirms the latest trend adopted by cybercrime gangs developing cross-platform ransomware that use languages like Rust and Golang to create malware capable of targeting multiple operating systems with little to no changes.

Other new ransomware families BleepingComputer reported this month include Lilith, C/C++ console-based ransomware targeting 64-bit Windows devices, and 0mega, a new ransomware operation targeting enterprises since May and demanding millions of dollars in ransoms.
