Anthropic AI release fuels crypto exploit fears

“Releasing a model this capable comes with risks. Without safeguards, Fable 5’s capabilities in areas like cybersecurity could be misused to cause serious damage,”

Said Anthropic.

Moonrock Capital founder Simon Dedic warned that Fable 5 could dramatically lower the barriers to discovering exploitable flaws in smart contracts, arguing that unaudited DeFi protocols could become increasingly vulnerable to attacks.

“For DeFi, this should be a massive wake-up call. Unaudited protocols will become sitting ducks. Known exploits will get replayed on forks around the clock. Even small projects will get targeted simply because trying costs next to nothing now,”

Said Moonrock Capital founder, Simon Dedic.

Dedic also urged crypto users to revoke wallet approvals, reduce exposure to DeFi protocols and transfer assets to fresh hardware wallets as a precaution against potential threats enabled by advanced AI systems.

Curve Finance co-founder Michael Egorov disputed the severity of the threat, arguing that smart contracts typically contain only a few thousand lines of code and are already well understood by both human auditors and existing AI tools, while suggesting operational security failures and supply-chain attacks may present a greater risk than direct smart contract exploits.

Anthropic said a limited group of cybersecurity and infrastructure providers will receive access to Claude Mythos 5, a version of the model with some safeguards removed, while the company maintains that Fable 5 has been made safe for general use through built-in restrictions on sensitive cybersecurity topics.
