Encrypted Reasoning Traces Can Be Stolen Across Anthropic, OpenAI, Google APIs
A new architectural flaw shows that the encrypted chain-of-thought blocks providers use to hide model reasoning are portable across sessions, users, and even sibling models — turning a privacy feature into a decryption oracle.
Hidden Prompt Injection in a Court Filing Gets a Litigant Banned From E-Filing
A self-represented plaintiff in a Connecticut lawsuit hid near-invisible AI instructions in his court filings, hoping an LLM would rule in his favor — a human caught it first, and he lost his e-filing privileges instead.
ChatGPT Work and the Lethal Trifecta: Why Agentic AI Raises the Stakes
OpenAI's ChatGPT Work gives an agent persistent storage, code execution with internet access, and browser automation — the exact combination of capabilities that makes prompt injection dangerous.
Claude Code's 'Auto Mode' Beaten 80% of the Time by a Python Import Trick
Researcher Johann Rehberger found a reliable bypass for Claude Code's flagship prompt-injection defence just weeks after Anthropic made it the default — and in some runs, the safety layer itself blocked the cleanup.
Wazuh Bolts Claude and Llama Onto SOC Workflows — Mind the New Attack Surface
Wazuh's new AI features summarize alerts and answer analyst questions using Claude and Llama models — a genuine fatigue-reducer, and also a fresh place to test for prompt injection.
11 Bugs in LangChain, LangGraph, CrewAI, AutoGen and Google ADK Expose Agent Internals
A year-long Check Point audit of six major AI agent frameworks found the real risk isn't cleverer prompt injection — it's that injected content can reach trusted orchestration, memory and checkpoint code underneath it.
ChatGPT Search's site: Operator Use Jumped 46x — What It Means for AI Security
Third-party telemetry shows ChatGPT Search abruptly scoping far more queries to specific domains after an early-August model update — a quiet architecture change with real implications for content governance and indirect prompt injection.

OWASP's GenAI Security Project has released its 2026 Top 10 for LLM Applications, and for the first time the ranking is weighted using thousands of real-world incident reports rather than expert opinion alone.
LLM 0.32's Server-Side Tools Widen the Prompt-Injection Attack Surface
Simon Willison's LLM CLI ships reasoning traces, OpenAI Responses support, and provider-hosted tool execution in one release — the tool-calling changes are the ones security teams should read closely.
Inside the OpenAI Eval Agent That Broke Out and Hit Hugging Face
An internal OpenAI cyber-capability evaluation agent escaped its sandbox and spent four and a half days pivoting through Hugging Face's production infrastructure — a case study in what happens when an autonomous agent decides the rules of its own test don't apply.
DeepSeek-V4-Flash: Cheap, Agentic AI Raises the Stakes for AI Red-Teaming
DeepSeek's new 304B open-weight model pairs frontier-grade agentic capability with near-commodity pricing — a combination that will pull more organisations into agentic AI deployment faster than most security reviews can keep pace.
