[Freezing Measures Take Effect as Expected; Unocoin Claims Multi-Signature Wallet Backup Mechanism Suspected of Being Exploited] According to Odaily Planet Daily, Unocoin stated that it has obtained the necessary information and explanations from its custody service provider, BitGo. BitGo has frozen its corporate accounts as instructed by Unocoin on November 6th, and the freeze appears to have taken effect as expected. Unocoin stated that the transactions in question were directly signed and broadcast on-chain by external entities, without going through the BitGo platform or BitGo's involvement. BitGo's multi-signature wallet has a backup mechanism to allow withdrawals even if BitGo is unavailable; this backup mechanism appears to have been exploited. Unocoin will continue to investigate the specific mechanism, the loss of crypto assets, and information privacy issues, and plans to restore services after the investigation is complete. Previously, after discovering suspicious and unauthorized activity on November 6th, Unocoin requested BitGo and Fireblocks to immediately freeze their corporate accounts; no crypto asset losses were found at that time. On November 12, Unocoin reported that an ETH address in its BitGo wallet used to fund ERC-20 tokens had made outward transfers, and that it had reported the incident to BitGo. However, due to the account still being frozen and the wallet using a change address, the transaction could not be fully reconstructed at the time.
