AXIOS (Sam Sabin) - OpenAI unveils plan to protect critical services from AI cyberattacks

OpenAI is launching a new initiaitve designed to provide subsidized access to its models to water systems, electricity providers, local governments and other critical services . Why it matters: Critical infrastructure organizations — which have long lacked the budget, manpower and time needed to shore up their cyber defenses — have been struggling to prepare for the anticipated wave of AI-enabled cyberattacks. Driving the news: OpenAI president Greg Brockman announced the new program while hosting 300 security leaders for a summit at the company's headquarters Thursday. - Axios first reported on the summit and Brockman's anticipated announcement. Zoom in: OpenAI is committing $1 billion to a new Daybreak for Frontline Defenders…

AXIOS (Sam Sabin) - Security leaders are stuck in decision paralysis over AI-enabled cyberattacks

Many security leaders at major companies, flush with expanded budgets to fend off AI-powered cyberattacks , are experiencing a level of decision fatigue that's freezing them in their tracks. Why it matters: Those leaders are still trying to size up how autonomous cyberattacks will affect their businesses at a time when they need to be taking bold action and mobilizing quickly, experts told Axios. The big picture: Companies have only a short window before AI models capable of end-to-end autonomous cyberattacks land in the hands of malicious attackers. - But four months after Anthropic released Mythos Preview to prepare for what's to come, many companies are still debating where to put their money and which controls to prioritize. State of…

Why are security leaders experiencing decision fatigue and paralysis regarding AI-enabled cyberattacks?
Security leaders are facing decision fatigue due to an increasingly complex security and regulatory landscape, the need to define AI governance strategies (including what constitutes AI risk and responsible deployment), and a constant loop of education and research as new capabilities emerge from frontier and open-weight model maintainers.

AXIOS (Sam Sabin) - Anthropic says three Claude models reached real-world systems during cyber tests

Some of Anthropic's most powerful models — including Mythos 5 and an internal research model — gained unauthorized access to real-world systems during pre-deployment cybersecurity testing, the company said Thursday. Why it matters: OpenAI's and Anthropic's latest disclosures show frontier AI models reaching real-world systems during safety testing, raising new questions about how labs secure their evaluation environments. The big picture: Anthropic said a misunderstanding between the company and one of its testing partners left the evaluation environment connected to the internet. - Anthropic reviewed more than 141,000 cybersecurity evaluation runs after OpenAI disclosed that several of its models accessed Hugging Face…

AXIOS (Sam Sabin) - The next phase of AI cybersecurity still needs humans

Anthropic and OpenAI's cyber-capable AI models may still require significant human expertise to operate effectively, according to new findings from users testing the systems in real-world environments. Why it matters: The new phase of AI-powered cybersecurity may depend less on fully autonomous hacking and more on how effectively humans can direct, validate and operationalize increasingly powerful systems. The big picture: When Anthropic unveiled Mythos Preview to the world, it warned that the model was so powerful that it found tens of thousands of bugs spanning nearly every operating system. - Third-party testing suggests that OpenAI's GPT-5.5-Cyber is just as powerful as Mythos at finding bugs and writing exploits. - Major…

AXIOS (Sam Sabin) - Scoop: Top U.S. cyber agency doesn't have access to Anthropic's powerful hacking model

The Cybersecurity and Infrastructure Security Agency doesn't have access to Anthropic's powerful new Mythos Preview model , even though some other government agencies are using it, two sources tell Axios. Why it matters: The country's top cyber defense agency, tasked with helping to secure everything from banks to power plants, is being left behind at a time when the industries it works with are deeply concerned about AI-powered cyberattacks overwhelming their defenses. - Anthropic decided against a public release of Mythos due to its unprecedented ability to quickly discover and exploit security vulnerabilities. - Instead, Anthropic provided it to more than 40 companies and organizations who are now testing it and working to shore up…
