What it detects

This rule detects the Windows ftp.exe client executing a script file through the -s flag, a living-off-the-land technique the JadeProx TriBack loader uses to run attacker-supplied commands from script.dat. Abusing ftp.exe as a script runner evades controls focused on interpreters. Detecting this invocation exposes JadeProx staging activity.
