In a significant development for the cryptocurrency community, Zcash co-founder Zooko Wilcox has announced that a recent security audit conducted by Anthropic's Mythos AI model revealed no additional serious vulnerabilities in the privacy-centric protocol. This finding comes shortly after a forgery bug was identified and patched, raising crucial questions about the integrity of Zcash's sophisticated shielded transactions.
Commissioned by Shielded Labs, a Swiss nonprofit devoted to advancing Zcash technology, the audit provides a reassuring update for users and stakeholders concerned about the protocol's robustness. On a social media post dated June 3, Wilcox stated, "The AI audit found no more serious bugs in the Zcash protocol," alleviating concerns that arose when developers briefly halted transactions on the Orchard network following the discovery of the forgery issue.
The problem originated from a four-year-old forgery bug detected by security researcher Taylor Hornby, with assistance from Anthropic's Claude Opus 4.8 model. Fortunately, the Zcash Foundation confirmed that no exploitation of the vulnerability was observed and that user privacy remained uncompromised throughout the incident.
Rising AI Challenges in Crypto Security
While developers increasingly turn to advanced AI models to identify potential vulnerabilities within blockchain protocols, these technological advancements also introduce new security challenges throughout the cryptocurrency landscape. Recent reports illustrate a dual-edged sword, with Anthropic’s newly launched public model, Fable 5, having previously uncovered over 10,000 critical vulnerabilities in essential software used across many sectors.
On June 9, Anthropic announced that access to Fable 5 and Mythos 5 would be suspended due to a U.S. government export control directive, which raised eyebrows regarding the implications for AI usage in cybersecurity. The emergence of such models has ignited debates about their overall safety and the extent of their influence on the recent surge in decentralized finance (DeFi) hacks, a concern articulated by industry experts.
The Cost of Vulnerabilities in the Crypto Sphere
Mitchell Amador, CEO of the bug bounty platform Immunefi, warned of a “vulnerability apocalypse” as hackers exploit potential weaknesses exacerbated by AI capabilities. In April, cryptocurrency hacks skyrocketed to $634 million—the highest monthly tally since a devastating $1.4 billion loss in February 2025 caused by the Bybit hack, according to data from DefiLlama.
As the landscape of AI-driven cybersecurity evolves, the mixed feelings surrounding such advancements only highlight the ongoing tug-of-war in safeguarding the future of digital currencies and the networks built around them.
