German Authorities Voice Concerns Over Claude Mythos Preview
German authorities have raised security concerns about Anthropic's Claude Mythos Preview, an AI tool introduced in early April that can find long‑undetected software vulnerabilities. Officials worry not only about the model falling into malicious hands but also that knowledge of vulnerabilities and capabilities to access encrypted communications could become accessible only to select U.S. authorities. Anthropic says it has no plans for public release and currently grants access to selected companies and organizations to fix software flaws. German agencies including the BKA, BSI and the Federal Ministry of Finance — via the Informationstechnikzentrum Bund — are actively analysing the implications while withholding detailed findings for sensitivity reasons.
A powerful LLM that can autonomously find software vulnerabilities raises cross-border security, sovereignty and law-enforcement access questions; affects cybersecurity posture and government policy discussions around controlling powerful AI tools.

Key Takeaways & Evidence Grounding
- Anthropic launched Claude Mythos Preview in early April as a tool for discovering software vulnerabilities.
- Anthropic does not plan to publicly release Mythos and limits access to selected companies and organisations.
- German agencies (BKA, BSI, Federal Ministry of Finance / Informationstechnikzentrum Bund) have raised concerns about security and national sovereignty implications.
- Carsten Meywirth, head of cybercrime at the Federal Criminal Police Office (BKA), said faster discovery and patching of vulnerabilities is positive but that threat actors adapt quickly.
- BSI President Claudia Plattner warned the tool could cause upheaval in how vulnerabilities are handled and raised questions about national and European security and sovereignty.

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.
Anthropic Withholds Claude Mythos Over Safety Risks
A commentary argues Anthropic’s Mythos announcement was overstated. The author and cited experts note the demo used an easier test configuration (sandboxing disabled), making it more a proof‑of‑concept than an immediate, real‑world threat. Observers cited tweets and analyses showing that small, inexpensive open‑weight models reproduced much of the same vulnerability analysis and that Mythos’ measured capability (normalized ECI) appears only slightly above recent models like GPT‑5.4. The piece concludes Mythos is incrementally better but not a dramatic leap, and the demo highlights the need for regulatory and technical preparedness rather than signaling imminent catastrophic risk.
