It uses ChaCha20-Poly1305 encryption with Argon2id-based key derivation, processes files in 1 MB chunks, and securely wipes its encryption key from memory after use. Unlike typical ransomware, it drops no ransom note on the system, instead conducting extortion communications out-of-band via email or dark-web portals to reduce forensic artifacts. It is not a RaaS operation and gains initial access via stolen RDP credentials, using legitimate RMM tools for persistence. At least five victims have been identified, including Standard Bank, which refused a 1 BTC ransom demand. ## Full article daily.dev links to this article rather than hosting it.
