The claim has three main parts: (1) Coinbase, Binance, and Fireblocks are seeking or testing Anthropic models; (2) this is connected to AI-driven security threats; and (3) there were newly disclosed vulnerability findings. The strongest directly aligned fetched source is the PANews article, which specifically attributes these details to The Information and names Coinbase, Binance, and Fireblocks with the described actions. The PANews article states Coinbase was in close communication with Anthropic on Mythos, Binance was testing vulnerabilities with Anthropic models, and Fireblocks had found a previously unidentified vulnerability using an earlier Anthropic model. That directly supports the user’s statement. The Information article URL was also observed via media tracing and search corroboration as the upstream report, but it could not be fetched in this run, so its validation remains null. Anthropic’s official pages, Project Glasswing and Assessing Claude Mythos Preview’s cybersecurity capabilities, do not mention Coinbase, Binance, or Fireblocks, but they strongly support the surrounding premise that Mythos is a restricted security-focused model and that Anthropic had recently disclosed major vulnerability-finding capabilities, including thousands of high-severity issues and a 27-year-old OpenBSD flaw. Together, these sources make the statement likely true, though confidence is medium rather than high because the core named-company reporting ultimately depends on a secondary fetched article plus an unfetched paywalled primary news report.
