Zcash founder Zooko Wilcox has announced that a recent audit conducted by Anthropic's advanced Mythos AI model has detected no additional serious vulnerabilities in the privacy-centric cryptocurrency’s protocol. This revelation follows heightened scrutiny after a forgery bug was identified earlier this month.
In a post on social media platform X, Wilcox confirmed that the security audit, requested by Shielded Labs—a Swiss non-profit dedicated to enhancing Zcash's security—found the protocol to be stable following the patching of the forgery issue. Wilcox emphasized that the Mythos model did not uncover any further ‘serious bugs’ in Zcash's architecture.
Earlier this month, developers temporarily halted Orchard transactions when a vulnerability in the shielded pool came to light. This problem was traced back to an older forgery bug that had been lingering for four years. With assistance from Anthropic's Claude Opus 4.8 model, security researcher Taylor Hornby was instrumental in diagnosing the flaw. Thankfully, the Zcash Foundation reported that there is no evidence suggesting the vulnerability was exploited, and user privacy remained unscathed.
AI’s Role in Crypto Security Under Scrutiny
The utilization of AI models for vulnerability detection is transforming the landscape of cryptocurrency security. However, this shift raises growing concerns about overall safety within the industry. Recently, Anthropic introduced the Claude Mythos model, Fable 5, to the public. The company disclosed that its Mythos model had previously unmasked over 10,000 high or critical-severity vulnerabilities in what it refers to as “systemically important software.” This revelation led to concerns about the model’s readiness for public release.
Anthropic asserts that Fable 5 has been tailored for general usage with built-in safeguards that redirect certain sensitive topics, such as cybersecurity, to the Claude Opus 4.8 model. Despite these reassurances, the company announced the suspension of access to both Fable 5 and Mythos 5 following a U.S. government directive concerning national security.
Rising Tide of Crypto Hacks
The introduction of sophisticated AI tools has inadvertently intensified vulnerabilities, leading experts to describe the current crisis as a “vulnerability apocalypse.” Mitchell Amador, CEO of the bug bounty platform Immunefi, highlighted a concerning trend, stating that the surge in cryptocurrency hacks reached $634 million in April 2026, marking the highest monthly value since the significant losses incurred during the Bybit hack in February 2025.
As developers and organizations continue to embrace AI for security, the balance between technological advancement and safety remains precarious. The recent audits and fixes in Zcash offer a hopeful glimpse into how proactive measures can mitigate risks, but the broader implications for the crypto sector are still unfolding.
