What it detects

This rule detects deletion of values under the Explorer RunMRU key, an anti-forensic step in newer NetSupport RAT ClickFix loaders. The malware removed RunMRU entries to erase evidence that the victim had pasted the malicious command into the Windows Run dialog. Programmatic clearing of RunMRU history is an indicator of indicator-removal activity.
