RansomHouse ransomware-as-a-service (RaaS) has upgraded its encryptor from a single-phase linear technique to a multi-layered method. The new 'Mario' encryptor variant uses a two-stage transformation with two keys, dynamic chunk sizing, and improved memory layout. This upgrade enhances encryption strength, speed, and reliability, making data recovery and analysis more challenging. RansomHouse, active since December 2021, has been linked to attacks on VMware ESXi hypervisors and recently targeted the Japanese e-commerce giant Askul Corporation.
