What it detects

This rule detects HTTP requests to FakeBat loader infrastructure including the MSIX delivery script dwnl.php and command and control endpoints such as check.php, buy and profile that carry victim fingerprint parameters like av, domain, key and os. These URI structures are specific to the FakeBat distribution and reporting channel. Matching them surfaces hosts fetching the loader or beaconing to adversary servers.
