Anthropic’s Mythos Claims Questioned by Cybersecurity Insider

Anthropic’s Mythos Claims Questioned by Cybersecurity Insider

More

Descriptions:

Cybersecurity researcher Jay, whose firm Aisle has been using AI for vulnerability discovery since August 2025, appears on Bloomberg Technology to challenge the claims surrounding Anthropic’s newly released Mythos model. The core argument: the specific vulnerabilities Anthropic disclosed as evidence of Mythos’s power — including findings in hardened codebases like OpenSSL — are reproducible using small, free open-source models, including ones as compact as GPT 5.4.

The interview highlights a central tension in how Anthropic has positioned Mythos. The company has restricted access to roughly 40 companies, citing the model’s dangerous potential. Jay pushes back, arguing the real capability lies not in the model itself but in the surrounding scaffolding and system design — making the exclusivity feel more like a business decision than a genuine safety measure. He also notes that Mythos’s capability profile is uneven, performing well on memory corruption and logic vulnerability classes but not uniformly strong across all security tasks.

Jay advocates for open-sourcing comparable vulnerability-detection tooling so that defenders globally — not just a small cluster of Silicon Valley firms — can proactively find and fix flaws in their own infrastructure. He points to a recent AI-assisted attack on the Mexican government as evidence that adversaries are already exploiting these capabilities at scale, raising the urgency for democratizing access on the defensive side.
