TA0003 · PERSISTENCE
BITS Jobs
Adversaries may abuse BITS jobs to persistently execute code and perform various background tasks. Windows Background Intelligent Transfer Service (BITS) is a low-bandwidth, asynchronous file transfer mechanism exposed through Component Object Model (COM).
Detect it with
BITS runs as a service and its status can be checked with the Sc query utility ( sc query bits ). Active BITS tasks can be enumerated using the BITSAdmin tool ( bitsadmin /list /allusers /verbose ).
Why it matters on shift
BITS Jobs is one of the concrete ways adversaries achieve persistence. Recognising it in telemetry lets you name the technique in your ticket and pivot to what came before and after.
What to look for next
After persistence, the next tactic is usually Privilege Escalation. Search your telemetry for the transition before closing the ticket.
