What it detects
This rule detects javaw.exe executing a JAR file that carries a .png extension, the execution technique used by the Sorillus Java RAT distributed in the SambaSpy multi-language phishing campaign across Europe. Adversaries rename the JAR with an image extension to disguise the payload while still running it through the Java runtime.
