PANews reported on October 2nd that ZachXBT monitoring revealed another unusual movement in the attacker's address (0x8Da...Ea30) linked to the Coinbase security incident. The attacker initially exchanged approximately 5 million DAI for 5 million USDC and, after holding the USDC for approximately 35 minutes, transferred the funds via a cross-chain bridge.

ZachXBT noted that Circle appears to have failed to freeze the USDC funds within that timeframe, with some of the funds reportedly being transferred via Circle’s official Cross-Chain Transfer Protocol (CCTP).
