Weekly Web3 Security Incident Roundup | Apr 6 – Apr 12, 2026

This BlockSec weekly security report covers four DeFi attack incidents detected between April 6 and April 12, 2026, across Linea, BNB Chain, Arbitrum, Optimism, Avalanche, and Base, with total estimated losses of approximately $928.6K. Notable incidents include a $517K approval-related exploit where a user mistakenly approved a permissionless SquidMulticall contract enabling arbitrary external calls, a $193K business logic flaw in the HB token's reward-settlement logic that allowed direct AMM reserve manipulation, a $165.6K exploit in Denaria's perpetual DEX caused by a rounding asymmetry compounded with an unsafe cast, and a $53K access control issue in XBITVault caused by an initialization-dependent check that failed open. The report provides detailed vulnerability analysis and attack transaction breakdowns for each incident.

Weekly Web3 Security Incident Roundup | Mar 30 – Apr 5, 2026

This BlockSec weekly security report covers nine DeFi attack incidents detected between March 30 and April 5, 2026, across Solana, BNB Chain, Arbitrum, and Polygon, with total estimated losses of approximately $287M. The week was dominated by the $285.3M Drift Protocol exploit on Solana, where attackers combined multisig signer social engineering with Solana's durable nonce mechanism to bypass a zero-timelock 2-of-5 Security Council, alongside notable incidents including a $950K flash loan TWAP manipulation against the LML staking protocol, a $359K Silo Finance vault inflation via an external `wstUSR` market donation exploiting a depegged-asset oracle and `totalAssets()` accounting flaw, and an EIP-7702 delegated-code access control failure. The report provides detailed vulnerability analysis and attack transaction breakdowns for each incident, covering flawed business logic, access control, price manipulation, phishing, and misconfiguration attack types.
