Web3 Security Incident Analysis: A certain trading platform's Cold Wallet suffered a major attack. On February 21, 2025, the Cold Wallet of a well-known trading platform was attacked, resulting in the transfer of approximately 401,346 ETH, 15,000 cmETH, 8,000 mETH, 90,375 stETH, and 90 USDT to an unknown address, with a total value of about $1.46 billion. The attacker uses phishing methods to lure the signers of the platform's multi-signature Wallet to sign malicious transactions. The steps of the attack are as follows: 1. The attacker pre-deploys a malicious contract containing a backdoor for fund transfers. 2. Tamper with the security management interface, causing the transaction information seen by the signer to be inconsistent with the data actually sent to the Cold Wallet. 3. Obtain three valid signatures by spoofing the interface, replace the implementation contract of the multi-signature Wallet with a malicious version, and then control the Cold Wallet to transfer funds.

Babylon is currently still in the development stage and has not yet launched an official blockchain or staking system. However, the influx of large amounts of capital may be related to the well-known cryptocurrency venture capital support behind it and its association with a certain trading platform. Babylon's vision is to become a presence similar to EigenLayer in the Bitcoin ecosystem, introducing concepts such as recursive staking. The staking mechanism of Babylon utilizes the time-lock feature of Bitcoin. Users create custom complex transactions.
