This threat detection rule monitors changes to the Windows registry specific to the BgInfo application, particularly focusing on any alterations to the database path. BgInfo, developed by Winternals, is used to display system information on the Windows desktop. Attackers may exploit this application by modifying the registry entry to redirect data outputs to an external database, potentially exfiltrating sensitive system information without detection. The rule triggers when a 'SetValue' event is detected for the registry path '\Software\Winternals\BGInfo\Database', indicating the configuration of a custom database path. Careful monitoring of these events is essential, as legitimate usage of BgInfo may also impact this registry entry, thus requiring further analysis before concluding malicious intent.
