攻击智能合约是开源的。
步骤 1：0x054e 发送交易，将管理员角色授予钱包 (0x41b8) 的 0x0eba。
然后 0x0eba 将“DAO 合约”角色授予 0x1c93。
最后，0x1c93 (XXX) 调用 withdrawFromUser 函数将资金转移到 XXX 合约。
有趣的是，受害者 0x41b8 是由 0x054e 创建的。
总而言之，0x054e 创建了受害者 0x41b8 钱包。然后 0x054e 将管理员角色授予 0x0eba，后者又将“DAO 合约”角色授予 0x1c93。最后 0x1c93 从受害者处提取了资金。
~$15.9M Lost: Trusted Volumes, Wasabi & More | BlockSec Weekly
This BlockSec bi-weekly security report covers 11 notable attack incidents identified between April 27 and May 10, 2026, across Sui, Ethereum, BNB Chain, Base, Blast, and Berachain, with total estimated losses of approximately $15.9M. Three incidents are analyzed in detail: the highlighted $1.14M Aftermath Finance exploit on Sui, where a signed/unsigned semantic mismatch in the builder-fee validation allowed an attacker to inject a negative fee that was converted into positive collateral during settlement; the $5.87M Trusted Volumes RFQ authorization mismatch on Ethereum; and the $5.7M Wasabi Protocol infrastructure-to-contract-control compromise across multiple EVM chains.
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.
