BlockSec 于 2023 年 03 月 17 日 05:48:59 (UTC) 成功阻止了一次针对 ParaSpace（一个顶级 NFT 借贷协议）的攻击企图，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，我们始终坚信更具主动性的威胁预防解决方案能够帮助抵御威胁。我们已于 2022 年内部部署了此类系统。截至本文撰写之时，我们的系统已成功阻止多次攻击，并为用户挽回了约 1400 万美元的资产。
请在本文中了解我们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性已得到社区的广泛认可，并且我们与社区中的一些顶尖合作伙伴进行了合作。例如，我们正与 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，其中包括 Phalcon Explorer（一个面向 Web3 开发者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）。
Drift Protocol Incident: Multisig Governance Compromise via Durable Nonce Exploitation
On April 1, 2026 (UTC), Drift Protocol on Solana suffered a $285.3M loss after an attacker exploited Solana's durable nonce mechanism to delay the execution of phished multisig approvals, ultimately transferring administrative control of the protocol's 2-of-5 Squads governance with zero timelock. With full admin privileges, the attacker created a malicious collateral market (CVT), inflated its oracle price, relaxed withdrawal protections, and drained USDC, JLP, SOL, cbBTC, and other assets through 31 rapid withdrawals in approximately 12 minutes. This incident highlights how durable nonce-based delayed execution can decouple signer intent from on-chain execution, bypassing the temporal assumptions that multisig security implicitly relies on.
