New NatJack Attacks Hijack TCP Sessions and Spoof DNS by Manipulating NAT Tables
NatJack, NAT, TCP hijacking, DNS spoofing, Black Hat
NatJack is a newly disclosed attack class targeting NAT state tables It enables TCP session hijacking, DNS spoofing, port exposure, and NAT table exhaustion Vulnerabilities were found across independently developed NAT implementations, including Windows
Emphasizes attacker capability and technical novelty while minimizing vendor responsibility for NAT implementation choices, lack of standardized state validation, or long-standing architectural assumptions that enabled the attack class.
Research-led threat discovery and responsible disclosure
NatJack is a new attack class that hijacks TCP sessions and spoofs DNS by manipulating NAT tables, affecting Windows and other implementations.
Vendor awareness timelines; Existing mitigations or workarounds; Root causes in NAT specification or implementation divergence
Combines authoritative venue attribution (Black Hat), named researcher credibility, and active-voice threat verbs ('hijack', 'spoof', 'exhaust') to foreground attacker agency. This makes the underlying architectural fragility — shared across vendors due to specification gaps or implementation shortcuts — feel like an external challenge rather than a systemic design liability, even though the claim centers on implementation behavior across 'independently developed' systems.
NatJack manipulates network address translation (NAT) connection state to hijack active TCP sessions, spoof DNS responses, expose mapped ports, and exhaust NAT tables.
Security researcher Malcolm Stagg has disclosed a new attack class called NatJack that manipulates network address translation (NAT) connection state to hijack active TCP sessions, spoof DNS responses, expose mapped ports, and exhaust NAT tables.
