Anthropic Mythos Vulnerability Claims Called 'Nothingburger' — VulnCheck Counts ~40 CVEs, Not Thousands

The Register·medium signal

The Register reports growing skepticism about Anthropic's claim that Mythos identified 'thousands of high- and critical-severity vulnerabilities.' VulnCheck researcher Patrick Garrity counts approximately 40 CVEs, and an independent Aisle replication study found that open-weight models produced much of the same vulnerability analysis. Security researcher Antani argued the unauthorized Mythos access is also a nothingburger because 'the adversary doesn't need Mythos to hack you.' The story is shifting from capability marvel to misinformation case study.
