What it detects

This rule detects the PolarEdge QNAP implant being launched with its distinctive connect-back argument set. The backdoor uses the cw mode flag together with the quiet foreground host and execute options to establish a reverse connection to its operator. This fixed argument combination is unique to the implant and reveals active backdoor invocation.
