SentinelLabs observed the first ELF variant of Cl0p (also known as Clop) ransomware variant targeting Linux systems on the 26th of December 2022. The new variant is similar to the Windows variant, using the same encryption method and similar process logic.
While the Windows versions contain a hashing algorithm in order to avoid encrypting specific folders and files, such functionality was not observed in the Linux variant. The ELF variant targets specific folders, subfolders and all files/types.
