Rapid7 Labs has identified a new malware-as-a-service information stealer being actively promoted through Telegram channels and on underground hacker forums. The stealer is advertised under the name “SantaStealer” and is planned to be released before the end of 2025.

Stolen data is then compressed, split into 10 MB chunks, and sent to a C2 server over unencrypted HTTP.
