What it detects

This rule detects creation of AlphaSeed working files inside the hidden .edge directory in the user profile, including the powermgmt.dat backdoor DLL, the cache_w.db keylog store and the schtaskw.exe self-copy. These files together in a hidden per-user folder are characteristic of a Kimsuky AlphaSeed infection staging keystroke capture and persistence.
