TA0005 · DEFENSE EVASION
Network Address Translation Traversal
Adversaries may bridge network boundaries by modifying a network device’s Network Address Translation (NAT) configuration.
Detect it with
Consider monitoring network traffic on both interfaces of border network devices. Compare packets transmitted by the device between networks to look for signs of NAT being implemented.
Why it matters on shift
Network Address Translation Traversal is one of the concrete ways adversaries achieve defense evasion. 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 defense evasion, the next tactic is usually Credential Access. Search your telemetry for the transition before closing the ticket.
