What it detects

This rule detects bitsadmin.exe invoked with a transfer job pointing to a remote URL. TA866 abused bitsadmin alongside certutil to pull additional payloads onto compromised hosts. Using the BITS admin tool to download files is a living-off-the-land ingress and BITS-jobs technique that evades naive download monitoring.
