TA0007 · DISCOVERY
Remote System Discovery
Finding other hosts by IP, hostname, or Active Directory to plan lateral movement.
Detect it with
Sequential SMB or ICMP connections to many internal hosts from one workstation in a short window.

What to look for next
After discovery, the next tactic is usually Lateral Movement. Search your telemetry for the transition before closing the ticket.
