在 2023 年 3 月 17 日 05:48:59（UTC），BlockSec 成功阻止了对 ParaSpace（一个顶级的 NFT 借贷协议）的攻击，保护了价值 500 万美元的加密资产。
正如我们在 上一篇博客 中提到的，我们始终相信，更主动的威胁预防解决方案可以帮助抵御威胁。我们在 2022 年内部部署了这样一个系统。截至本文撰写之时，我们的系统已成功阻止了多次攻击，并为用户挽回了约 1400 万美元的资产。
请参阅我们在这篇文章中关于主动威胁预防的观点。
我们的解决方案的可行性和实践已得到社区的广泛认可，并与社区中一些顶尖的合作伙伴进行了合作。例如，我们正在与 Compound 合作，为 Compound V3 智能合约开发风险预防系统。
我们始终致力于为 Web3 社区构建区块链安全基础设施，包括 Phalcon Explorer（一个面向 Web3 开发人员和安全研究人员的交易分析工具）、MetaDock（一个面向 Web3 用户的安全工具箱）以及 MetaSleuth（一个面向 Web3 用户的资金追踪工具）。
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.
