Anthropic releases Claude Fable 5 as DeFi hacks top $840M in first five months

Anthropic has released Claude Fable 5, a new AI model it says offers stronger reasoning and coding while blocking the most dangerous uses, as DeFi protocols have lost more than $840 million to hacks in the first five months of the year. According to CoinDesk, Anthropic also made a more capable version, Claude Mythos 5, available only to vetted users in cybersecurity and critical infrastructure, with high-risk requests routed to a weaker Claude Opus 4.8 model in fewer than 5% of sessions.

Anthropic's Mythos AI finds no more 'serious' bugs in Zcash: Wilcox

The issue stemmed from a four-year-old forgery bug in the Orchard shielded pool that was discovered by security researcher Taylor Hornby with the help of Anthropic's Claude Opus 4.8 model. The Zcash Foundation said there was no evidence that the vulnerability was exploited, nor was there any unauthorized value creation detected, while user privacy was unaffected. The proliferation of these new AI models has shifted the cybersecurity playing field in favor of the threat actors, causing a “vulnera
