Security Insights & Updates

A frontier AI model surfaced an under-constrained circuit flaw in Zcash's Orchard pool that survived four years and multiple audits. Here is the postmortem and the lesson for Web3.

Anthropic released Claude Fable 5 and Mythos 5 on June 9, 2026, calling Mythos the strongest cybersecurity model in the world. Here is what it changes for smart contract security.

Anthropic's Mythos preview found thousands of zero day bugs in weeks. Here is what that means for Web3 security, and why smart contracts need their own defender.

Cecuro achieved 87.17% detection on EVMBench, nearly double the next-best AI system, making Cecuro industry-leading in AI smart contract auditing. Here's what the benchmark tells us about AI smart contract security.

A full breakdown of every major smart contract exploit in May 2026, from the $11.6M Verus bridge hack to THORChain's threshold signature breach.

A full breakdown of every major smart contract exploit in April 2026, from the $292M Kelp DAO bridge attack to the $285M Drift Protocol social engineering heist

Cecuro reported an Alchemix V3 accounting bug through their bug bounty program. A stale storage snapshot caused 49% under-earmarking on live Optimism. $1,000 bounty awarded.

How a single verifier configuration on a LayerZero bridge let attackers drain 116,500 rsETH from Kelp DAO, trigger $6.6B in Aave withdrawals, and spread contagion across nine DeFi protocols.

Cecuro discovered a medium-severity gas DoS vulnerability in GoGoPool's WithdrawQueue that could block all AVAX withdrawals for ~$310 in gas.

Cecuro ran Claude Code on three DeFi audit contests across Sui Move and Solidity. 93 findings, 0 valid. Here's what we learned about AI false positives — and why specialized tooling matters

We benchmarked our AI security agent on 90 real exploited contracts ($228M losses). 92% detection rate, $96.8M protected. Full research and dataset open-sourced.

Claude Code's security reviews are great for web apps. Smart contracts need specialized AI. Traditional audits cost $30K-500K. AI is necessary, but only if it's built for blockchain.

OpenClaw can code, analyze vulnerabilities, and work 24/7. As AI agents become sophisticated, the threat to smart contracts is real and urgent.

Technical breakdown of the Makina Finance flash loan exploit. Learn how unvalidated oracle data enabled share price manipulation, and how to protect your protocol.

Smart contract audit costs range from $5,000 to $300,000+. Learn what drives pricing, how to reduce costs without sacrificing security, and why AI-powered audits are changing the game.

Technical breakdown of the Truebit Protocol exploit. Learn how an integer overflow in getPurchasePrice() enabled unlimited token minting, and how automated audits catch these vulnerabilities.

Learn why blockchain security audits are critical in 2026. Explore real exploits, transaction hashes, best practices, tools, and a battle-tested audit workflow from Cecuro.

Human-only audits delay launches and cap TVL. This deep dive quantifies the hidden costs, explains why speed is a security feature, and shows how Cecuro’s automated audit engine converts security into a same‑day workflow that compounds growth.
