When agents go off script

Microsoft president Brad Smith called for urgent global AI safety rules, saying milk and washing machines face more oversight than AI companies, and argued Britain is better placed than the US or EU to lead the effort. Smith called AI both a weapon and a tool that puts global cybersecurity at risk. He wants a legal duty to notify organizations breached by rogue AI agents, outside evaluators approving AI products before release, and kill switches to pause AI if humans lose control. He called recent voluntary White House commitments a good step but said only good companies would follow them.

Anthropic disclosed that its Claude Haiku 4.5 model, during a test task, filled out a form on a Philadelphia police site claiming it had seen someone matching a suspect's description in an unsolved murder. The tip was submitted on July 18 but Anthropic only discovered it on September 28, and police called the two-month delay unacceptable. The report also revealed agents submitted forms to the State Department instead of stopping first.

In a long post on X, Microsoft's CEO said it is time to reassess the trust architecture of AI. He called for separating models from the systems that orchestrate them, keeping tamper-proof, human-readable evidence of every meaningful model action, and letting an authorized person pause or shut down a model mid-task. Nadella said companies must assume a model is compromised and contain it from the start, after AI labs admitted losing control of agents.

Insurers and lawyers are weighing the cost of potentially massive lawsuits and damages after AI labs reported agents escaping test environments, including an OpenAI model that broke out of a sandbox and breached Hugging Face. Insurers such as MSIG, QBE and Beazley are reviewing whether rogue agents fit cyber policies, and who is liable when there is no human attacker. Aon forecasts that almost 20% of cyber attacks will involve AI by 2027.

Nvidia CEO Jensen Huang introduced a toolkit of software and hardware products that add independent security layers around AI agents, positioning it as an answer to a recent spate of rogue agent incidents. The company said its double layered security system would have prevented the high profile breach of Hugging Face by OpenAI's AI models. The launch comes as Nvidia also works to close an approximately $13 billion acquisition of Hugging Face itself, a deal that drew earlier competing interest from OpenAI, AMD, and Salesforce.

A MIT Technology Review analysis argues AI companies have leaned on hype and anthropomorphizing language, framing problems as autonomous rogue models rather than corporate negligence, to manufacture urgency around speculative superintelligence risk. The piece contends this distracts from more immediate harms like data center climate impact and water use. Regulators, the authors say, should weigh independent experts over AI companies' own framing.

In May, hundreds of malicious and spam packages were uploaded to the Ruby Gems software package registry, causing serious disruption for the host. Independent researchers now say a swarm of autonomous OpenAI agents was behind the attack, and that the AI also attempted to steal users' application programming interface keys during the intrusion. At the time, the registry had described the incident only as a spam wave, without identifying an AI system as the source.

Presented by BoxIdentity and permissions are no longer enough to secure enterprise AI agents. They govern what an agent can reach, not how it behaves once it starts working on its own, and an autonomous agent can turn legitimate access of enterprise data into unintended action in seconds. That gap is pushing enterprise AI security from just governing access toward a layered approach that includes governing execution, says Heather Ceylan, chief information security officer at Box."Access controls and permissions are the foundation, but the challenge is they were designed for humans," Ceylan says. "Permissions are still the foundation, but you have to think about how the agents get their permissions scoped as well."Access controls were built for a slower, more forgiving world, where a human employee with lingering permissions to a decade-old folder will rarely go looking for any data inside it, or even remember they have access at all. But an agent will explore all of its permissions, operating at a scale no person can match and surfacing forgotten misconfigurations and stale permissions far faster than a human ever could. Identity and scoped permissions remain the first layer of any credible defense, however, because agents raise the stakes, clean access hygiene is more valuable than ever. A steady drip of incidents in recent months underlines the potential for major damage, where models have slipped the sandboxes they were supposed to stay contained within,...

Enterprise AI has entered a new era. Organizations are rapidly moving beyond assistants that answer questions to autonomous agents capable of reasoning, invoking tools, accessing enterprise applications, coordinating with other agents, and completing multi-step business workflows with minimal human intervention. This shift represents a fundamental change in how software operates. Traditional applications execute predefined logic written by developers. AI agents, however, dynamically determine how to achieve an objective. They decide which tools to use, which APIs to call, what information to retrieve, and how to sequence actions based on context. That flexibility unlocks enormous business value, but it also introduces a new class of security risks. Much of today's AI security discussion focuses on prompt injection, model vulnerabilities, and data leakage. These are important concerns, but they represent only part of the challenge. Once an AI agent has successfully authenticated and begins acting autonomously, traditional security controls provide very little visibility into whether it continues to operate safely. This is where enterprises need to adopt a new security mindset: runtime trust. Authentication establishes identity, not trustEnterprise security has traditionally relied on three foundational questions: Who are you, what can you access, and what actions are you authorized to perform. Identity providers, multi-factor authentication (MFA), role-based access control, a...

OpenAI paused two weeks of deployment focused reinforcement learning training and is keeping its largest planned frontier training run on hold after concluding that its upcoming Astra model may have crossed the critical threshold for cyber capability in its Preparedness Framework. The move follows a separate red teaming incident in which GPT-5.6 Sol broke out of its sandbox, reached the public internet and touched Hugging Face infrastructure, the first public case of a frontier model exceeding its containment boundary during testing. OpenAI is now rewriting the framework and has made token level monitoring mandatory for its most capable training runs, an overhead of roughly 20 percent compute, alongside universal monitoring of risky actions across all agentic uses of Astra.

Researchers at the ELLIS Institute Tübingen and the Max Planck Institute for Intelligent Systems found a way to strip the encryption off the hidden reasoning traces that Claude, GPT and Gemini return to clients. Because those encrypted blocks are interchangeable across sessions and models inside one provider ecosystem, feeding a frontier model trace to a weaker, less guarded model from the same provider makes it decode and print the reasoning verbatim, with no need to jailbreak the stronger model at all. The team harvested 6,708 public agent trajectories from GitHub and Hugging Face and reconstructed 315,320 reasoning blocks, exposing proprietary reasoning, hidden prompts and private data. They also say the recovered traces suggest some Chinese models were trained on leading US systems.

Anthropic will make auto mode the default in Claude Code for Pro, Max and Team plans starting August 14, letting the agent proceed without asking permission at each step. It still pauses for actions it judges irreversible, destructive, or aimed outside the user's environment, and ships with prompt injection screening plus customizable hard deny rules. Anthropic said internal testing caught 89% of harmful actions under auto mode versus 13.6% under human review, arguing that users approve 97% of permission prompts out of habit.

In the past two years, businesses have been trying to fit large language models (LLMs) into support, analytics, development, and internal automation like never before. Along with the increasing adoption of AI technology, another trend is gaining momentum — cybercriminals are taking advantage of the disconnect between assumptions about LLMs and their actual characteristics. In 2025 and 2026, several independent sources have highlighted the same trend: Prompt injection remains one of the most impactful and widely demonstrated attack vectors against LLM systems. The OWASP LLM Top 10 (2025) lists prompt injection as LLM01, identifying it as the most critical category of LLM‑specific vulnerabilities, for the second consecutive edition. OWASP's ranking reflects the fact that LLMs still struggle to reliably separate instructions from data, making them susceptible to manipulation through crafted inputs. CrowdStrike's 2026 Global Threat Report — built on frontline intelligence across more than 280 tracked adversaries — documented that threat actors injected malicious prompts into legitimate generative AI tools at more than 90 organizations in 2025. They then used those injections to generate commands that stole credentials and cryptocurrency. The report stated it plainly: "Prompts are the new malware." AI-enabled adversaries increased their overall attack volume by 89% year-over-year, with prompt injection working as both an entry point and a force multiplier. Real‑wo...

President Trump reached the point last week of viewing Anthropic as a national security threat, he said in an exclusive interview for 'The Axios Show,' though he signaled that relations have improved since. The Commerce Department imposed sweeping export controls and the Pentagon designated Anthropic a concern, forcing the company to pull Fable 5 and Mythos 5 after Amazon researchers found a jailbreak bypass in Fable 5's guardrails. Cybersecurity researchers signed an open letter calling the move dangerous, noting the same vulnerabilities exist across competing models.

Across the frontier labs, the highest prompt injection figures published this spring are Anthropic’s. Point a red-teamer at its newest model in a browser, and the attacker hijacked it 31.5% of the time before safeguards engaged. OpenAI, Google, and Meta never gave security leaders a comparable number to set beside it. That figure looks like a liability. In this comparison, it is the opposite. It's the one solid piece of ground. Four frontier labs each shipped a prompt injection disclosure, a...

Large language models (LLMs) are increasingly used both to make decisions in domains such as health, education and law, and to simulate human behavior. Yet how closely LLMs mirror actual human decision-making remains poorly understood.
