According to on-chain risk monitoring data, suspicious addresses related to UXLink security vulnerabilities have been active recently. In the past hour, this address completed a large exchange: 248 WBTC was swapped for 23 million DAI.

The background of this transfer is noteworthy. The incident can be traced back to the hacker attack on September 22nd — the attacker exploited a vulnerability to mint billions of unauthorized tokens and stole crypto assets worth tens of millions of dollars. It now appears that the hacker is digesting the stolen funds, and the exchange from WBTC to DAI may be part of money laundering or withdrawal preparations. This also serves as a reminder for the community to continuously monitor on-chain abnormal transfers, especially transactions involving large amounts of stablecoins.
