What it detects
This rule detects download or script-execution commands recorded in the Explorer RunMRU history, the forensic residue left when a user pastes a clipboard-injected command into the Run dialog during a paste-jacking or ClickFix attack. Adversaries rely on this manual execution path to bypass download controls, making mshta or PowerShell cradle strings in RunMRU a useful post-execution indicator.
