Weekly Web3 Security Incident Roundup | Mar 2 – Mar 8, 2026

During the week of March 2 to March 8, 2026, seven blockchain security incidents were reported with total losses of ~$3.25M. The incidents occurred across Base, BNB Chain, and Ethereum, exposing critical vulnerabilities in smart contract business logic, token deflationary mechanics, and asset price manipulation. The primary causes included a double-minting logic flaw during full token deposits that allowed an attacker to exponentially inflate their balances through repeated burn-and-mint cycles, a price manipulation vulnerability in an AMM-based lending market where artificially inflated vault shares created divergent price anchors to incorrectly force healthy positions into liquidation, and a flawed access control implementation relying on trivially spoofed contract interfaces that enabled attackers to bypass authorization to batch-mint and dump arbitrary tokens.

Weekly Web3 Security Incident Roundup | Feb 23 – Mar 1, 2026

During the week of February 23 to March 1, 2026, seven blockchain security incidents were reported with total losses of ~$13M. The incidents affected multiple protocols, exposing critical weaknesses in oracle design/configuration, cryptographic verification, and core business logic. The primary drivers included oracle manipulation/misconfiguration that led to the largest loss at YieldBloxDAO (~$10M), a crypto-proof verification flaw that enabled the FOOMCASH (~$2.26M) exploit, and additional token design and logic errors impacting Ploutos, LAXO, STO, HedgePay, and an unknown contract, underscoring the need for rigorous audits and continuous monitoring across all protocol layers.
