Cs‑137 is a newly observed ransomware strain that first appeared in January 2025. It employs the ChaCha20 cipher for encryption and appends obfuscated filenames with a random 10-character alphanumeric identifier while preserving the original file extension. In its current testing phase, it drops a ransom note with a randomized filename (e.g. ABCDEF-README.txt) and sets a randomly named image file as the desktop wallpaper. The note references a Tor-based extortion portal—though access is not yet active, indicating the operation’s early development stage. The strategy suggests single-extortion behavior, focused on disrupting access rather than data theft or leak threats.

Dire Wolf is a sophisticated human-operated ransomware group first documented in May 2025, written in Golang using Curve25519/ChaCha20 encryption, targeting manufacturing and technology sectors across 13+ countries with ransoms up to $500,000, operated by a tight core team rather than a broad affiliate program.
