The newest AI model from Anthropic, which gives users access to stronger, faster reasoning and coding capabilities, lands in a crypto market beset by security problems and could well exacerbate them.
Key facts
- In one, a North Korea-linked group drained about $285 million from Drift Protocol after a six-month social-engineering campaign that won it admin access
- Io.net's IDE ties token burns to real GPU demand, replacing fixed emissions with a demand-linked model
- live as of 11 June 2026
- Another example hit on Tuesday, when Humanity Protocol, a decentralized human-identity service, lost over $30 million to a private-key compromise
- DeFi protocols have lost more than $840 million to hacks in the first five months of the year, DefiLlama data shows
Summary
Anthropic’s Claude Fable 5 model offers stronger reasoning and coding abilities while attempting to block dangerous uses. Security experts warn that advanced AI will not invent fundamentally new crypto hacks, but will dramatically speed up finding misconfigurations and constructing ways of exploiting weaknesses such as social engineering, exposed keys and flawed signing flows. This year’s largest DeFi losses, totaling more than $840 million, have mostly stemmed from human error and operational failures rather than smart-contract bugs. The company released Claude Fable 5 on Tuesday, the first public model in the Mythos class and, Anthropic says, its most powerful yet.
