 2024年7月18日,据Beosin Alert监控预警发现印度交易所WazirX被攻击,攻击者获取到交易所多签钱包管理员的签名数据,修改钱包的逻辑合约,让钱包执行错误的逻辑,来盗取资产,涉及资金超2.35亿美元。

基于攻击者的攻击行为,推测原因为多签钱包的管理员私钥泄露,Beosin将攻击原因简析如下:

攻击者地址:

0x6eedf92fb92dd68a270c3205e96dccc527728066

被攻击地址:

0x27fd43babfbe83a81d14665b1a6fb8030a60c9b4

首先,攻击者部署攻击合约:

0x27fd43babfbe83a81d14665b1a6fb8030a60c9b4。

该合约的功能是提取本合约指定的代币资产。

第二步,攻击者获取到wazirx多签钱包管理员的签名数据,将钱包的逻辑合约修改为已经部署好的攻击合约。

对应交易为:

https://etherscan.io/tx/0x48164d3adbab78c2cb9876f6e17f88e321097fcd14cadd57556866e4ef3e185d

第三步,攻击者向wazirx多签钱包提交提取代币交易,由于代理模式的机制,钱包合约会利用delegatecall调用攻击合约的相关函数,转走钱包代币。

Beosin Trace对被盗资金进行追踪,被盗资金部分的流线图,目前来看,黑客已经将部分资金转移进入Changenow与Binance交易所,其中0xf92949ab576ac2f8dc9e4650e73db083f1f9cd9f为黑客在Binance的充币地址。

另一方面,黑客在过去两小时向地址0x35fe...745CA转移8010亿枚SHIB,价值高达1402万美元,正在持续分批抛售,目前黑客地址仍持有4.9万亿枚SHIB,总价值8652万美元。

Beosin Trace正在对被盗资金进行持续追踪。

Why Is No One Buying DeFi Insurance?

"Why DeFi Insurance Remains Unpurchased" explores the paradox of decentralized finance insurance. While DeFi insurance promises automatic, unbiased payouts via smart contracts—eliminating traditional insurers' denial practices—it struggles to attract users. The core issue is economic viability. Premiums are prohibitively high relative to the yields from DeFi protocols. For example, insuring a deposit on Aave or Maple Finance can consume most or even all of the annual yield, leaving returns comparable to or worse than traditional savings. Only the safest protocols, like MakerDAO, offer affordable premiums. Furthermore, the DeFi insurance model is structurally fragile. Unlike traditional insurance where risks are uncorrelated, DeFi risks are highly interconnected (e.g., oracle failures, bridge hacks). A single major exploit can simultaneously threaten multiple protocols, potentially bankrupting the entire insurance pool, which holds only millions against billions in total value locked. The governance model also creates a conflict of interest. In platforms like Nexus Mutual, token holders who vote on claims risk their own capital if payouts are approved, incentivizing denials. Consequently, the market is tiny and shrinking. Nexus Mutual dominates with $81.56 million in assets, but the industry lacks the capacity to cover a catastrophic event like the $292M Kelp DAO hack. Other providers have dwindled or shut down. The article concludes that DeFi insurance faces a "tragedy of the commons": its stability requires widespread adoption, but individual users have no incentive to pay for it, as premiums destroy their yields. Current solutions involve preventative measures like bug bounties and seeking external capital from traditional reinsurance, acknowledging that on-chain capital alone is insufficient to cover on-chain risks.
