NatJack Attacks Hijack TCP Sessions and Spoof DNS via NAT Table Manipulation
Researchers have uncovered a new attack technique dubbed NatJack that exploits network address translation (NAT) tables to hijack active TCP connections and spoof DNS responses. By manipulating stateful NAT devices, attackers can intercept or redirect traffic without credentials, posing a serious threat to network security. This matters because it undermines trust in standard internet connections and may affect many enterprise and home routers.
