What it detects

This rule detects web requests to the fixed HTTP command-and-control endpoints used by the Splinter post-exploitation red-team implant, including its heartbeat, task-event, and file-transfer paths. These structured URI patterns are unique to the tool and indicate an active implant beaconing to its controller.
