New Java-Based QuimaRAT MaaS Built to Run on Windows, Linux, and macOS

A new Java-based remote access trojan (RAT) named QuimaRAT has emerged as a malware-as-a-service (MaaS) offering, targeting Windows, Linux, and macOS systems. The malware features a modular architecture with encrypted plugins delivered from command-and-control (C2) infrastructure and supports cross-platform persistence mechanisms. It includes tools for stealthy delivery, such as browser-cache staging and fileless execution, while evading detection through trusted execution paths and obfuscation techniques.
