SantaStealer Malware-as-a-Service Launching This Holiday Season

A new malware-as-a-service called SantaStealer, previously known as BluelineStealer, is set to launch before the end of 2025. Advertised on Telegram and hacker forums, SantaStealer is designed to collect sensitive information, including credentials and cryptocurrency wallet data, and operates in memory to evade detection. The service is reportedly offered by a Russian-speaking developer for a subscription fee.
