Newsletter - April 2026
In April 2026, the DeFi ecosystem experienced three major security incidents. KelpDAO lost ~$290M due to an insecure 1-of-1 DVN bridge configuration exploited via RPC infrastructure compromise, Drift Protocol suffered ~$285M from a multisig governance takeover leveraging Solana's durable nonce mechanism, and Rhea Finance incurred ~$18.4M following a business logic flaw in its margin-trading module that allowed circular swap path manipulatio
~$7.04M Lost: GiddyDefi, Volo Vault & More | BlockSec Weekly
This BlockSec weekly security report covers eight attack incidents detected between April 20 and April 26, 2026, across Ethereum, Avalanche, Sui, Base, HyperLiquid, and MegaETH, with total estimated losses of approximately $7.04M. The highlighted incident is the $1.3M GiddyDefi exploit, where the attacker did not break any cryptography or use a flash loan but simply replayed an existing on-chain EIP-712 signature with the unsigned `aggregator` and `fromToken` fields swapped out for a malicious contract, demonstrating how partial signature coverage turns any historical signature into a generic permit. Other incidents include a $3.5M Volo Vault operator key compromise on Sui, a $1.5M Purrlend privileged-role takeover, a $413K SingularityFinance oracle misconfiguration, a $142.7K Scallop cross-pool index injection, a $72.35K Kipseli Router decimal mismatch, a $50.7K REVLoans (Juicebox) accounting pollution, and a $64K Custom Rebalancer arbitrary-call exploit.
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.
