What it detects

This rule detects creation of HKCU Run key values named OFFICE or DIVXX, the specific autorun entries Red Canary attributed to Scarlet Goldfinch for persisting its NetSupport Manager deployment. These named values are non-standard for legitimate software, so their appearance under the CurrentVersion Run path indicates adversary persistence.
