A multi-signature address was attacked, and approximately 1,337 ETH were transferred out, then moved into a hidden fund pool. The assets are valued at nearly $3.9 million. The security team traced the transfer and found that the moved funds included Wrapped ETH and Story tokens, both originating from suspicious withdrawal records of the multi-signature wallet. This incident once again highlights the vulnerabilities of multi-signature mechanisms in certain scenarios and reminds ecosystem participants to evaluate their fund management strategies more cautiously. Similar large-scale transfer events occur frequently on Ethereum, and the market needs more transparent security tracking mechanisms.
