RTM Locker is a recently emerged ransomware that targets enterprise systems, specifically Linux virtual machines on VMware ESXi servers. This malicious software was developed from the leaked source code of the now-defunct Babuk ransomware, which was made public by an alleged member of the Babuk group in September 2021. The leak led to the creation of numerous new variants throughout 2023, including ESXiArgs, Rorschach, and RTM Locker, as well as the RA Group. The Linux variant of RTM Locker, along with other ransomware groups such as Royal, Black Basta, LockBit, Qilin, ESXiArgs, Monti, and Akira, are known for directly targeting victims' VMware ESXi servers. These groups steal and encrypt files, subsequently demanding substantial ransoms. Notably, Uptycs has observed some differences between RTM Locker and its parent Babuk ransomware, despite their shared origins. The source code leaks of both Paradise and Babuk in mid-2021 have underpinned the emergence of several new ransomware families, including MortalKombat, RA Group, RTM Locker, ESXiArgs, and Chaos 4. Newcomers like RA Group, Rorschach, and RTM Locker also utilize the leaked Babuk source code. The latest variant of RTM Locker, which specifically targets Linux, NAS, and virtual machines on VMware ESXi hosts, underscores the ongoing threat and evolution of these ransomware attacks.
