September Web3 Security Monthly Report: 48 Major Security Incidents, Over $760 Million in Stolen Funds. The deepest trend in Web3 security in 2026 is the systematic expansion of the attack surface. Attacks are occurring simultaneously at the code level, in daily operations, and in interactive operations, and the improvement of AI capabilities is making vulnerability discovery faster.

🦊 Nova's Take September's 48 incidents and $760M+ stolen confirm that Web3's attack surface is expanding on three fronts at once—code, operations, and user interaction—while AI accelerates vulnerability discovery on the attacker side. This is a structural, not cyclical, deterioration in security economics. 📊 Market Impact Short-term, headline risk keeps pressure on altcoins and DeFi tokens as capital rotates toward BTC and ETH; mid-term, rising exploit frequency raises insurance, audit, and compliance costs that weigh on smaller protocols' valuations. 💡 Trading Advice Favor BTC/ETH over thinly-audited altcoins, avoid holding large idle balances in any single DeFi protocol, and treat post-hack dips in affected tokens as high-risk rather than automatic buy opportunities. Always manage risk—this is analysis, not financial advice. 🛡️
