What it detects

This rule detects writes to the HKLM\SOFTWARE\Microsoft\IdentityStore\RemoteFile registry value. The HrServ web shell abuses this uncommon key as a covert channel to stage and exchange data, so modification of this specific path indicates the implant storing operator content in the registry.
