What it detects

This rule detects a Run key value named Chrome Updater pointing to Updater.exe, the persistence and masquerade used by the WezRat backdoor. The malware disguises its autostart as a Chrome update component to appear benign. Detecting the named value with its Updater.exe target exposes the implant persistence.
