What it detects

This rule detects creation of the FrostyNeighbor dropper artifacts under an AppData WinDataScope folder, specifically Update.js and WinUpdate.reg. These files are staged by the JavaScript dropper to seed later stages and registry persistence, so their appearance in this path indicates an active infection.
