Digital Assets Watch: Crypto’s next billion-dollar hacker may move at superhuman speed

Latest reporting indicates that the newest AI model from Anthropic, which gives users access to stronger, faster reasoning and coding capabilities, lands in a crypto sector beset by security problems and could well exacerbate them.

The company released Claude Fable 5 on Tuesday, the first public model in the Mythos class and, Anthropic says, its most powerful yet.

So powerful, in fact, the company released two versions: one for widespread use and the other for more restricted distribution.

The public version sports stronger reasoning and coding ability while blocking the most dangerous uses.

A less-hamstrung counterpart, Claude Mythos 5, is available only to vetted users in cybersecurity and critical infrastructure.

Experts say Mythos can find and chain zero-day vulnerabilities, or previously unknown software flaws, and help turn a bug into a working attack.

Anthropic says the software tries to intercept possible attack vectors by detecting high-risk requests.

Once identified, they are routed to a weaker model, Claude Opus 4.8.
