AI Is Helping Discover Tech Vulnerabilities—And Zcash Is Just the Latest Example
Frontier AI models are now being used to hunt software bugs, and Decrypt says one helped uncover a Zcash flaw that could have minted unlimited ZEC.

Decrypt says frontier models such as Claude Opus 4.8 and GPT-5.5 are moving from coding helpers to security tools. In crypto, that shift showed up in a Zcash privacy-pool bug that may have gone unnoticed for years.
It is like a super-smart flashlight that can scan a giant maze of code and spot hidden traps. In Zcash’s case, that flashlight helped find a bug that might have let someone make fake coins.
Analysis
AI becomes a security tool
The article argues that frontier AI models are no longer limited to chat, image generation, or code writing. Researchers are increasingly using systems such as Anthropic’s Claude Mythos and Claude Opus 4.8, along with OpenAI’s GPT-5.5, to review code and identify vulnerabilities across browsers, operating systems, and open-source software.
Why crypto is exposed
Decrypt says crypto and DeFi are especially vulnerable because much of the code is public and the incentives are large. The clearest example in the piece is Zcash: independent security researcher Taylor Hornby disclosed a critical flaw in the Orchard privacy pool with help from Claude Opus 4.8. According to the article, the bug could have let an attacker mint unlimited ZEC, and it remained undetected for years before being patched.
The reporting also notes an important limitation: because of Orchard’s privacy design, there is no definitive cryptographic way to tell whether the exploit was ever used. That uncertainty matters because it leaves both users and markets without a clean answer about past damage.
The article places this in a broader security context. It says DeFi has already suffered heavy losses in 2026, with more than $840 million stolen in the first five months of the year. It also points to the rise of “vibe hacking,” where AI coding agents are used to automate reconnaissance, credential theft, malware development, and related tasks. The core message is that the same tools making bug hunting more effective are also lowering the barrier to more capable attacks.
Decrypt quotes security professionals saying the real shift is not AI replacing hackers, but amplifying them. At the same time, defenders can use the same systems for monitoring and simulation, which means the race is increasingly about who adopts the tools faster.
Key points
- Frontier AI models are increasingly being used as vulnerability-finding tools, not just coding assistants.
- Decrypt says Claude Opus 4.8 helped reveal a critical Zcash bug in the Orchard privacy pool.
- The flaw could have allowed unlimited ZEC to be minted, but it is unknown whether it was actually exploited.
- Because Orchard is designed for privacy, there is no definitive cryptographic way to confirm exploitation.
- The article frames AI as both a defender’s tool and a way to amplify attackers.
The article suggests AI can help security teams find dangerous flaws faster than humans alone. If defenders use the same tools well, bugs may be patched before they can be abused, and monitoring could improve across crypto systems.
The same AI tools that help find bugs can also help attackers automate more of their work. The article warns that open-source crypto projects may become easier targets, and privacy-focused designs can make it hard to know whether a flaw was exploited.
