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...
Malware Can Abuse Windows Hello for Business Keys for Persistent Entra ID Access
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, disclose victim IP addresses and mapped ports, and exhaust NAT...
Claude Code and Gemini CLI Flaws Let a GitHub Issue Reach CI Workflow Secrets
A GitHub issue opened by an account with no repository privileges was enough to execute code on the CI runners behind Anthropic's and Google's own coding-agent repositories. On OpenAI's, it was enough to hijack the next agent run. Novee Security ran the attack against...

New Zapscape KVM Flaw Could Let Privileged L1 Guest Code Escape to Linux Hosts
Zapscape, a new Linux kernel vulnerability, could allow an attacker with kernel privileges inside an L1 guest virtual machine (VM) to escape KVM isolation and execute code on the host. The risk applies when nested virtualization is exposed to untrusted guests. The...
New Interrupt Injection Attack Can Bypass Spectre v2 Defenses on Intel and AMD CPUs
An unprivileged Linux program can time a hardware interrupt to land in the gap between a processor sanitizing its branch predictor and the kernel using it, re-poisoning the predictor after the defense has run. MIT CSAIL researchers Daniël Trujillo and Mengjia Yan...
