What it detects

This rule detects the Quick Assist remote assistance tool spawning a command interpreter or download utility, a technique used in social engineering attacks where operators abuse Quick Assist to run scripted downloads. Storm-1811 leveraged this to fetch Qakbot and Cobalt Strike leading to Black Basta ransomware, so a legitimate support binary launching cmd, PowerShell or curl warrants investigation.
