对Wintermute项目指控的简要分析

在调查了 James Edwards (@libreshash) 发表的题为 Wintermute 被黑分析:内部作案 (本报告) 的报告后,我们认为对 Wintermute 项目的指控并不像作者声称的那样确凿。

0x1. 账户 0x0000000fe6a514a32abdcdfcc076c85243de899b 的权限

报告只是查找了映射变量 _setCommonAdmin 中账户的当前状态,但这并不合理,因为该项目在知晓攻击后可能会采取行动撤销管理员权限。

_setCommonAdmin[0x0000000fe6a514a32abdcdfcc076c85243de899b] 的存储槽位密钥是 0x1488acaeec0884899a8f09209808003200bbe32c28e8f074961d28a1dc78daa1,我们已经相应地调查了历史上的存储变更。结果显示,在以下两个交易中,该值被修改了两次:

第一次修改只是将值从 0 更改为 1,而第二次则将值从 1 更改为 0,如下所示:

请注意,报告中分析的攻击发生在区块 15572515 (0xd2ff7c138d7a4acb78ae613a56465c90703ab839f3c8289c5c0e0d90a8b4ce16),这在第一次修改和第二次修改之间。

显然,第二次修改该值意味着该项目刚刚撤销了该账户的管理员权限。

0x2. 可疑活动

报告将以下活动视为可疑:

然而,这并没有他们声称的那样可信。攻击者可以通过监控转账交易的活动来实现目标。从技术角度来看,这并不算奇怪。例如,存在一些链上 MEV 机器人会持续监控交易以获利。

0x3. 结论

总之,本报告的证据不足以指控 Wintermute 项目。

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 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.

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.
