QuimaRAT is a cross-platform, Java-based remote access trojan sold as a malware-as-a-service subscription on the dark web. It targets Windows, macOS, and Linux systems by embedding JNA native libraries for multiple architectures within a JAR archive built for Java SE 8. The RAT decrypts an internal configuration file using repeating-key XOR, performs anti-analysis and virtualization checks, establishes persistence via OS-specific mechanisms, and maintains resilient C2 communication through HANDSHAKE and HEARTBEAT protocols. With 23 implemented commands and 212 protocol-only commands, the platform is highly extensible through runtime modules and fileless payloads.

Kaspersky's 2025 compromise assessment report reveals that organizations consistently fail to detect long-dwelling threats, with 30.8% of incidents persisting over 3 months and 52% of high-severity compromises going undetected for 90+ days. Key findings include widespread abuse of LoLBins and remote management tools in every incident-bearing engagement, 40% of web shells surviving in backups to be restored post-remediation, and a strong correlation between in-house forensics/reverse-engineering capability and reduced incident severity. Multiple case studies document dormant crypto-mining on domain controllers (4 years), in-memory LionTail implants on critical servers, PurpleFox rootkit infections evading EDR with disabled memory scanning, and ClipBanker persistence via registry Run keys with Defender exclusions.
