AI-Assisted HTTP Terminator Finds Novel HTTP Desync Techniques and Apache Zero-Day

PortSwigger says HTTP Terminator, an artificial intelligence (AI)-assisted research system built by James Kettle, generated and proved new HTTP desynchronization techniques after exploring 30,000 candidate attack vectors.

PortSwigger said a separate human-guided discovery cascade also exposed a zero-day in Apache Traffic Server. Kettle said HTTP Terminator tested 30,000 websites where scanning

New NatJack Attacks Hijack TCP Sessions and Spoof DNS by Manipulating 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.

Presented at Black Hat USA 2026, the research found affected behavior across independently developed implementations, including Windows and

Malware Can Abuse Windows Hello for Business Keys for Persistent Entra ID Access

Entra ID researcher Dirk-jan Mollema demonstrated that malware already running in a signed-in Windows session can silently use the victim’s Windows Hello for Business key to authenticate to Microsoft Entra ID.

The attacker can then establish longer-term cloud access, register a device it controls, obtain a Primary Refresh Token (PRT), and add further authentication methods where tenant policies
