New NatJack Attacks Hijack TCP Sessions and Spoof DNS by Manipulating NAT Tables
A security researcher unveiled NatJack, a novel attack class that exploits network address translation (NAT) connection state to hijack TCP sessions, spoof DNS responses, and expose mapped ports. The attack affects multiple independent NAT implementations, including Windows, and was presented at Black Hat USA 2026.
Why it matters: Network infrastructure teams and organizations relying on NAT for internal security should evaluate their implementations for susceptibility to session hijacking and DNS spoofing, as the attack impacts widely deployed systems.
