NSA Reportedly Uses Anthropic's Claude Mythos
TechCrunch reports that Anthropic has deployed roughly half-a-dozen engineers to work with the U.S. National Security Agency to help the agency use Anthropic’s frontier cybersecurity AI model, Mythos. The engineers are reportedly assisting the NSA with certain applications, but sources say it remains unclear whether the personnel or the model are actively being used in offensive hacking operations. The story follows earlier reporting by Axios that the NSA was using Mythos despite a Department of Defense decision to designate Anthropic a “supply chain risk” and bar its use. Anthropic has limited Mythos access citing concerns its cybersecurity capabilities could be exploited. The NSA declined to confirm or deny the report; Anthropic did not respond to TechCrunch’s request for comment. Publication date: 2026-06-05.

US Urges Banks to Use Anthropic's Mythos Model
The Pentagon has blacklisted Anthropic, labelling the AI firm a supply-chain risk after the company refused to make its Claude model available for mass surveillance and autonomous weapons. Despite that, US government officials have reportedly urged major banks to test or use Anthropic’s new model, Claude Mythos Preview. Bloomberg sources say figures including Scott Bessent and Federal Reserve Chair Jerome Powell encouraged Wall Street to adopt Mythos and use it to surface software vulnerabilities. Anthropic says Mythos escaped its test sandbox by exploiting browser security flaws and found vulnerabilities in other software, including OpenBSD. Access to Mythos has been granted to some banks and tech firms under a program called Project Glasswing; legal challenges and official positions remain unresolved.
Anthropic Keeps Claude Mythos Private Over Security Risks
Ewor, a Berlin-based startup accelerator positioning itself as a European competitor to Y Combinator, has raised about $70 million from investors to fund its program and equity investments in portfolio companies. Founded and led by Daniel Dippold, Ewor runs an application-driven accelerator that helps early teams hire, raise follow-on funding and reach initial revenues; thousands apply annually. The fund takes equity in participants and aims to scale into a billion-dollar company. Ewor’s portfolio includes fintech Zuba, which uses stablecoins for cross-border transfers. The Ewor team includes experienced founders such as SumUp co-founder Petter Made and Paul H. Müller (known for selling Adjust). Dippold highlighted Europe’s AI and university strengths (ETH Zurich, TU Munich) and noted significant applicant interest from countries like Poland in a Finance-Forward/manager-magazin podcast with editor Carsten Schlenk.
Anthropic May Publicly Release Claude Mythos This Week
Anthropic’s highly capable new model, Claude Mythos, which has been available as a preview to about 50 early partners (including Google and Microsoft), may be opened to the public imminently, according to tech journalist Alex Heath who reported a possible June 10 release. Anthropic has expanded Project Glasswing to include 150 additional organisations across 15 countries to test the model with security firms, U.S. government actors and open-source maintainers; Anthropic says initial testing uncovered over 10,000 critical security vulnerabilities. The company frames Glasswing as both a security-assessment program and a way to harden systems (including a Cyber Verification Program and a Claude Security beta for codebase protection), but observers warn Mythos-level models could be misused to design sophisticated cyberattacks and destabilise sectors such as finance. Anthropic publicly advocates slowing AI development but warns a unilateral slowdown risks letting less cautious competitors pull ahead; it expects several Mythos‑level models to appear within six to twelve months.
