关于 Ronin Bridge 黑客事件

2022 年 3 月 29 日,Ronin Network 发布官方公告,警示社区 Ronin Bridge 的安全事件。具体而言,攻击者通过攻破 Ronin 验证者节点获取了私钥,并通过两次攻击交易从 Ronin Bridge 盗取了 173,600 ETH 和 25,500,000 USDC。

两次交易的详情如下:

追踪被盗资金

攻击者在获利后立即将被盗的 USDC 兑换成 ETH。具体来说,被盗的 USDC 被转移到 Uniswap 和 1inch,并使用了两个中间节点,即 0x6656 和 0xe708,来进行来回兑换。兑换完成后,所有被盗资金都变成了 ETH。

3 月 28 日,攻击者开始转移 ETH。截至 3 月 30 日,攻击者已从攻击地址转移出 6,250 ETH 到交易所,其中包括分别转移到 FTX 的 1,220 ETH、转移到 Huobi 的 3750 ETH 和转移到 Crypto.com 的 1 ETH。

好消息是,这些交易所愿意协助项目方追回被盗资金。

结论

截至撰写本文时,攻击地址仍持有约 175,913 ETH,而有 1,279 ETH 正在转移中。我们将持续监测被盗资金的追踪情况,并及时与社区分享我们的发现。

其他数据

攻击者已获取 182,162.86 ETH。其中,173,600 ETH 直接来自项目盗窃,8,562.86 ETH 来自被盗的 USDC。

  • 初始资金:1.0569 ETH 来自 Binance
  • 被盗 ETH:173,600 ETH
  • 从被盗 USDC 兑换的 ETH:8,562.86 ETH(4869.18508653411 到 Uniswap,3693.6752093176137 到 1inch)

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.
