Anthropic launched Claude Fable 5 with enhanced coding. Security researchers warn the AI can speed up crypto heists by finding vulnerabilities faster. Pendle uses it defensively.
Alpha Score of 62 reflects moderate overall profile with strong momentum, moderate value, moderate quality, moderate sentiment.
Anthropic launched Claude Fable 5, its most advanced AI model, alongside a more powerful version called Claude Mythos 5. Mythos is restricted to approved organizations in cybersecurity and critical infrastructure. The public model has stronger reasoning and coding abilities, with safeguards meant to block dangerous misuse.
Security researchers said the model's ability to identify and connect previously unknown software vulnerabilities, known as zero-day flaws, could help build sophisticated cyberattacks. Anthropic said high-risk requests are automatically redirected to a less capable model, a safety check that activates in fewer than 5% of user sessions. Charles Guillemet, chief technology officer at Ledger, said the main advantage AI gives attackers is speed, not innovation. Advanced AI can scan code repositories, compare software updates, and find configuration mistakes much faster than a person can.
The crypto sector is especially exposed because software failures often lead directly to financial losses. DeFi protocols have lost more than $840 million to hacks in the first five months of this year, according to industry trackers. The biggest incidents were not smart contract exploits but social engineering and compromised private keys. Attacks on Drift Protocol, Kelp DAO, and Humanity Protocol showed how operational security failures remain the primary threat, researchers said. AI can make reconnaissance more efficient by analyzing public data, reviewing audit reports, and crafting convincing phishing messages.
The same AI technology can strengthen defenses too. Pendle, a DeFi protocol, uses Anthropic's models to review code and stress-test smart contracts before deployment, developers there said. They argued that smart contracts are relatively compact and easier to audit than the broader operational systems around them.
For crypto participants, the biggest shift may not be new attack methods but the speed at which existing threats can be executed. Strong key management, hardware wallets, and trusted signing processes remain the baseline defenses in an environment where attackers have faster tools. The crypto market will need to match that speed on the defensive side as well.
