What it detects

This rule detects a CurrentVersion Run autorun value whose command runs wscript with the JavaScript engine against a script staged in ProgramData, the persistence behavior of a Konni AsyncRAT chain registered as GUpdate2 or SUpdate. Adversaries leverage the run key with the scripting host to relaunch their JavaScript loader at logon while masquerading as an updater, making early detection critical for surfacing persistence before AsyncRAT reconnects.
