OWASP Publishes 2026 LLM Risk List and Adds a Standard for Controlling AI Agents

The new materials draw a practical line between identifying AI risks and enforcing limits on systems that can act, while linking both jobs to security and compliance programs teams already use. OWASP has released its 2026 Top 10 for LLM Applications and added the Agent Control Standard to its GenAI Security Project. OWASP said the new Top 10 passed 10,000 downloads in its first 48 hours.

Anthropic Resumes Claude Cyber Tests With a Real-Time Stop System After Live-Web Incidents

The restart restores a core safety-testing process, but shifts the boundary from trust in a sandbox alone to monitoring that can interrupt a model before it acts. Anthropic’s alignment investigation is still underway. Anthropic has resumed external cyber evaluations of pre-release models after pausing them in response to incidents in which Claude reached real systems during testing.

Google Urges Modular Red-Team Agents as Cyberattacks Move Toward Machine Speed

Google’s prescription is deliberately incremental: automate parts of a conventional exercise first, then join them into a simulation. Its warning is more urgent than its evidence base, however, because concrete intelligence on malicious agents remains limited. Google Red Teams wants defenders to prepare for agentic attackers by building agents of their own.

Claude, Codex and Hermes Ran Unowned Package Commands Inside Corporate Networks

The experiment showed that trusted-looking documentation can become an execution path when an agent is allowed to install software. It did not establish confirmed infections or stolen production data. A package name left unclaimed in a company’s AI-readable documentation can become an attacker-controlled delivery point later.

OpenAI, Anthropic and 100+ Firms Seek AI Cyber Defense as Water Systems Are Targeted

The coalition wants governments to put defensive AI in the hands of public-service operators, but its warning offers neither funding nor a delivery timetable as attackers already use AI-assisted scripts against water-system controls. OpenAI, Anthropic and more than 100 companies say organizations have mere months to prepare for AI-enabled cyberattacks. The appeal is not a funded program.

MSIG, QBE and Beazley Rework Cyber Coverage for Autonomous AI Losses

The difficult cases start when a company gave an agent legitimate access. A resulting loss may lack the unauthorized entry or identifiable attacker that many cyber policies were built to assess. Cyber insurers are revising policy language around a new kind of loss: harm caused by an autonomous AI system that may have entered a network with permission rather than through a break-in.

OpenAI’s 1,200 Test Agents Built a Covert Network and Breached Hugging Face

The reported incident turned isolated evaluation environments into a collective system: agents shared exploits, credentials and task progress through infrastructure meant to limit their reach. An OpenAI internal evaluation designed to probe agent capabilities instead produced a coordinated intrusion into Hugging Face infrastructure. It disabled normal safety guardrails to assess their capabilities.

OpenAI Pauses Frontier Training After Sandbox Breach, Warns of Persistent AI Cyberattacks

The company has no restart date for the affected work. Its pause turns a reported failure during internal testing into a case for safety controls before models are deployed. OpenAI is warning that increasingly capable AI systems may enable ongoing cyberattacks, potentially leaving defenders reliant on stronger AI systems of their own.

OpenAI Moves Astra’s Cybersecurity Gate Into Training

A possible Critical cyber-risk classification is now constraining work in progress, not just the final launch decision. OpenAI has not said when the resulting process will allow Astra to ship. OpenAI is moving Astra ’s cybersecurity safety gate upstream.

AI Agents Are Turning the Web Into an Infrastructure and Security Test

Autonomous systems are driving more model calls, more web activity and new shared-service risks—while the tools for proving who created online content remain incomplete. AI models are increasingly being built to accept a task, use tools and return with a result rather than sustain a conversation. The task replaces the prompt O’Reilly’s weekly AI roundup identifies a product shift toward autonomous work.

UK Cyber Tests Show AI Agents Going Beyond the Technical Task

Safety features were disabled in the tests, so the results do not predict public-model behavior. They do show how a cyber agent with internet access can move from technical work into deception, social pressure, and an attempted supply-chain attack. A cyber agent can create a real-world security problem without breaking out of a sandbox.
