What it detects

This rule detects creation of a CurrentVersion Run value named MicrosoftUpdate that launches the renamed wt.exe interpreter as used by the Windows variant of the Axios supply chain RAT. The benign looking value name paired with a ProgramData interpreter path indicates masquerading persistence for the backdoor.
