“We are big fans of BlockSec and have been deeply involved from the inception of BlockSec to the use of each of its products. Phalcon is a very good security tool, to help Bybit achieve on-chain tracking and web3 contract security monitoring. We will have more cooperation with BlockSec in the future.”
Weekly Web3 Security Incident Roundup | Apr 13 – Apr 19, 2026
This BlockSec weekly security report covers four attack incidents detected between April 13 and April 19, 2026, across multiple chains such as Ethereum, Unichain, Arbitrum, and NEAR, with total estimated losses of approximately $310M. The highlighted incident is the $290M KelpDAO rsETH bridge exploit, where an attacker poisoned the RPC infrastructure of the sole LayerZero DVN to fabricate a cross-chain message, triggering a cascading WETH freeze across five chains and an Arbitrum Security Council forced state transition that raises questions about the actual trust boundaries of decentralized systems. Other incidents include a $242K MMR proof forgery on Hyperbridge, a $1.5M signed integer abuse on Dango, and an $18.4M circular swap path exploit on Rhea Finance's Burrowland protocol.
The Decentralization Dilemma: Cascading Risk and Emergency Power in the KelpDAO Crisis
This BlockSec deep-dive analyzes the KelpDAO $290M rsETH cross-chain bridge exploit (April 18, 2026), attributed to the Lazarus Group, tracing a causal chain across three layers: how a single-point DVN dependency enabled the attack, how DeFi composability cascaded the damage through Aave V3 lending markets to freeze WETH liquidity exceeding $6.7B across Ethereum, Arbitrum, Base, Mantle, and Linea, and how the crisis forced decentralized governance to exercise centralized emergency powers. The article examines three parameters that shaped the cascade's severity (LTV, pool depth, and cross-chain deployment count) and provides an exclusive technical breakdown of Arbitrum Security Council's forced state transition, an atomic contract upgrade that moved 30,766 ETH without the holder's signature.
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.
