President Donald Trump postponed signing an executive order that would have required U.S. agencies to evaluate artificial‑intelligence models before they reach the market. The president said he was uncomfortable with language that could hinder America’s lead in AI, and reports suggest the delay also reflects a lack of immediate availability of tech CEOs for briefings. The stalled order would have tasked the Office of the National Cyber Director and other agencies with creating a pre‑release security review process, a move spurred by the launch of Anthropic’s Mythos and OpenAI’s GPT‑5.5 Cyber.

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. Leggi di più

OpenAI announced that its upcoming GPT-5.5 model performed on par with the heavily promoted Mythos Preview in recent cybersecurity evaluations. CEO Sam Altman criticized the hype surrounding Mythos, calling it fear‑based marketing, while reiterating that the new model will initially be available only to a select group of critical cyber defenders. The company’s Trusted Access for Cyber pilot, launched in February, continues to serve as the gateway for researchers and enterprises to test frontier models under strict safeguards. Leggi di più

OpenAI announced it will roll out its GPT-5.5 Cyber suite to a select group of "critical cyber defenders" in the coming days, mirroring Anthropic's recent restriction of its Mythos tool. CEO Sam Altman posted on X that access will be granted through an application process that verifies users' credentials and intended use. The move aims to keep the powerful capabilities—penetration testing, vulnerability exploitation, and malware reverse engineering—from falling into the hands of malicious actors while the company consults with the U.S. government on broader availability.

OpenAI chief Sam Altman accused rival Anthropic of using fear‑mongering to promote its new cybersecurity model, Mythos, during a recent podcast appearance. Altman suggested the rhetoric was designed to keep advanced AI tools in the hands of a select few, echoing broader industry debates about hype, safety and market positioning. Leggi di più

Anthropic's new Mythos AI model has sparked concern among security experts after data from CrowdStrike showed AI‑enabled cyber attacks jump 89 percent in 2025. The model's ability to automate vulnerability hunting could overwhelm defenders, with internal warnings that companies may discover more flaws than they can patch. Recent incidents, including a Chinese‑linked AI espionage campaign that used Anthropic's Claude Code to breach dozens of high‑profile targets, underscore the growing threat. Analysts argue that granting AI agents unrestricted access to data, the internet, and external communication creates a “lethal trifecta” for hackers. Leggi di più

The National Security Agency has begun using Anthropic’s new Mythos Preview, a general‑purpose language model touted for its strength in computer‑security tasks. Sources familiar with the rollout say the NSA is one of roughly 40 agencies granted access and that usage is expanding within the department. The move comes despite a months‑long feud between the AI firm and the Pentagon, a February order from former President Trump to halt government use of Anthropic services, and ongoing lawsuits over the company’s designation as a supply‑chain risk.
