JRE process execution of unsigned JAR payload (QuimaRAT)
Detects the execution of Java processes with a -jar argument where the JAR file is located in a non-standard, user-writable directory (e.g., Temp, Downloads) and the process is initiated by an unexpected parent application (e.g., shell, explorer). This pattern is indicative of the execution of QuimaRAT or similar Java-based malware.
