What it detects

This rule detects an autorun value whose data references an alternate data stream on the user profile. Gamaredon hides GammaPhish payloads in named streams such as USERPROFILE GTR and points a Run entry at them for stealthy persistence. Autorun values pointing into alternate data streams are a strong sign of hidden payload persistence.
