Fable 5 Launch Sparks AI DeFi Hack Fears as April Losses Hit $629M

Anthropic’s June 10 public release of Fable 5 has intensified market concerns that AI tools could accelerate smart-contract exploits, arriving as year-to-date crypto losses reached $629.7 million in April alone. The development caps a week of cascading Ethereum-linked security incidents that began with UXLINK and Gravity Bridge exploits, continued through a misfired MEV bot transfer and Joseph Lubin’s defensive 110,000 ETH collateral deposit, and culminated in ZachXBT’s allegation that the $32 million Humanity Protocol breach was staged alongside aggressive whale shorting of ETH. Heightened scrutiny now surrounds bridges, mixers, and unaudited protocols as ETH trades near multi-month lows.
