What it detects

This rule detects creation of scheduled tasks named brokerhost or net_queue_32 through schtasks.exe. These task names were used for persistence in the exposed WebDAV malware delivery campaign analyzed by Rapid7. The distinctive task names combined with scheduled task creation indicate an attacker establishing automated re-execution of downloaded payloads.
