TL;DR:
- Anthropic released its advanced Claude Mythos model, showcasing unprecedented capabilities in identifying critical flaws in software development.
- Internal cybersecurity testing revealed that automated agents powered by this model can detect vulnerabilities in smart contracts representing millions in cumulative value.
- Web3 auditing platforms suggest the preemptive removal of unlimited spending allowances to mitigate automated exploit vectors.
The advancement of frontier artificial intelligence models has raised alarms within the decentralized finance (DeFi) ecosystem. Following the public deployment of tech firm Anthropic’s new suite of advanced models, several security analysts have issued urgent alerts aimed at protecting user funds. The core recommendation dictates that investors must immediately revoke their DeFi wallet approvals.
Security tips ahead of Mythos launch:
• revoke all your token approvals
• use only heavily audited dApps
• spread your funds across multiple wallets to reduce single points of failureHopefully Mythos will help good actors find vulnerabilities before hackers do. https://t.co/wybPi5Sl8q

Automated Exploit Capabilities and Smart Contract Risk
Specialists’ concerns intensified following the release of performance data for Anthropic’s cybersecurity-focused model series. According to the firm’s evaluations on its specialized smart contract testing platforms, variants of this architecture successfully identified exploitable security gaps representing a cumulative financial risk of $4.6 million in previously audited code.
Data from Anthropic suggests that this technology drastically reduces the time and cost required to structure complex exploit chains. A technical analysis by independent security platform XBOW detailed that the model provides unprecedented accuracy in executing web exploits and automated code audits. Researchers point out that a malicious software agent equipped with this inference engine could scan the blockchain en masse to locate smart contracts with lingering logical flaws and autonomously drain funds.
The direct danger for the average user lies in the historical approvals granted to protocols when performing swaps or providing liquidity. According to Web3 sector technical reports, many applications request unlimited spending permissions over wallet assets. If an old or deprecated smart contract contains an unpatched vulnerability, the analysis speed of the new AI system could allow malicious actors to detect the flaw and exploit it before protocol developers can deploy a security patch.
Mitigation Procedure Ahead of the AI Launch Window
In light of this scenario, multiple blockchain security infrastructure providers recommend mitigating the attack surface by interacting with dedicated revocation tools such as Revoke.cash or Etherscan Token Approval. The technical process consists of severing the authorization link between the user’s private key and the third-party smart contract addresses that retain rights to move the stored tokens.
Data from auditing firms indicates that maintaining open approvals with infinite parameters stands as the primary vector for financial losses in protocol breach incidents. With the deployment of the commercial version of the model at a cost of $25 per million input tokens, the accessibility of these analytical tools will become widespread among researchers and code developers globally over the coming days of June.
The closest regulatory and operational milestone to measure the impact of these automated defense and attack systems will take place on August 2, 2026, the date on which the next phase of the European Union Artificial Intelligence Act (EU AI Act) will enter into force. This phase will mandate automated audit trails and strict governance records for all models classified under the systemic risk category.
