The U.S. Commerce Department deleted a web page that described an agreement in which Microsoft, Google and Elon Musk's xAI would submit their most advanced AI models to government scientists for security testing before public release. The page, first posted on May 5, vanished Monday afternoon and now redirects to the Center for AI Standards and Innovation, the agency that runs the tests. Neither the department nor the Trump White House offered an explanation, and the three companies have not commented. The removal comes amid shifting federal AI policy and ongoing debate over giving the government pre‑release access to frontier AI systems. Read more

OpenAI unveiled Daybreak on May 11, 2026, a new cybersecurity service that leverages its latest AI models, including GPT‑5.5 and Codex Security, to automate vulnerability detection, patch generation and audit reporting. The initiative positions OpenAI against Anthropic’s Claude Mythos and comes with a roster of partners such as Cloudflare, Cisco, CrowdStrike, Palo Alto Networks, Oracle and Akamai. Read more

OpenAI unveiled Daybreak, a new AI‑driven security platform that combines its latest GPT‑5.5‑Cyber models with the Codex Security agent. Designed to map an organization’s code, predict attack paths and auto‑detect high‑risk flaws, Daybreak aims to stay a step ahead of cyber attackers. The rollout follows Anthropic’s controversial Claude Mythos release and marks OpenAI’s first foray into dedicated vulnerability‑prevention tooling, with the company pledging collaboration with industry and government partners as the service scales.

Google’s Threat Intelligence Group disclosed that a criminal hacking crew used an artificial‑intelligence model to locate a zero‑day flaw in a widely used open‑source system‑administration platform. The vulnerability could have bypassed two‑factor authentication and enabled a mass exploit across multiple organizations. Google intervened, alerted the software’s developers, and helped roll out a patch before the attack could be launched. The report, which does not identify the attackers, the software, or the AI model, also notes growing interest from state‑linked groups in AI‑assisted hacking tools. Read more

Meta announced the purchase of Moltbook, a niche social platform built for autonomous AI agents, as part of its intensified push into artificial intelligence. The Moltbook team will join Meta’s Superintelligence labs, but the company has offered no details on how the technology will be used. Industry observers warn that integrating a network where AI agents communicate freely could expose Meta’s massive user base on Facebook, Instagram and WhatsApp to new security risks, reviving concerns about the firm’s handling of personal data.

Intruder, a UK cybersecurity startup, has launched AI pentesting agents that replicate manual pen testing methodology in minutes, threatening to replace human pen testers. The company's AI agents work by investigating vulnerability scanner findings, interacting with target systems, and determining whether findings represent genuine exploitable flaws or false positives.

Anthropic's Claude Mythos Preview, an AI model, has identified thousands of zero-day vulnerabilities in major operating systems and browsers, prompting the Federal Reserve chair and Treasury secretary to convene an emergency meeting with bank CEOs to discuss the cyber risks. The company warns of a six-to-twelve month window to patch the flaws before adversaries replicate the capability. Read more

Akamai Technologies' stock had its best day in 22 years, rising 27% after the company announced a $1.8 billion, seven-year cloud deal with Anthropic, a leading AI provider. The contract is Akamai's largest ever and marks a significant pivot into AI infrastructure. Read more

Mozilla’s Firefox team says Anthropic’s new Mythos model has identified dozens of high‑severity vulnerabilities, many lurking for over a decade. The AI‑driven scans helped the browser ship 423 bug fixes in April 2026, a stark jump from 31 the previous year. Researchers credit the model’s ability to self‑filter false positives and generate detailed reports, though human engineers still write and review patches. The breakthrough signals a shift in software security, but Mozilla warns that attackers could eventually co‑opt similar tools. Read more

Braintrust, a platform that helps companies monitor AI models, disclosed an unauthorized access incident in one of its Amazon Web Services accounts. The breach exposed customer API keys used to access cloud‑based AI services. In an email sent Monday, the company asked every client to revoke and replace those keys as a precaution. Braintrust says the incident is contained, the compromised account has been locked down, and internal secrets have been rotated while the cause remains under investigation. Read more
