TA0007 · DISCOVERY
System Information Discovery
An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, hotfixes, service packs, and architecture.
Detect it with
System and network discovery techniques normally occur throughout an operation as an adversary learns the environment. Data and events should not be viewed in isolation, but as part of a chain of behavior that could lead to other activities based on the information obtained.
Why it matters on shift
System Information Discovery is one of the concrete ways adversaries achieve discovery. 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 discovery, the next tactic is usually Lateral Movement. Search your telemetry for the transition before closing the ticket.
