The victim of the wrong transfer of 1155#BTC~ $68 million is Vietnamese

Developments :

On the evening of May 3, an anonymous user due to an address poisoning attack mistakenly transferred to a phishing attacker 1,155 WBTC worth 68 million USD at that time.

On May 4, the victim asked the attacker to return 90% of the money and agreed to let the attacker keep 10%. After a period of silence, the attacker suddenly returned 51 ETH and requested communication via Telegram on May 9.

On May 10, the victim responded to an on-chain message from the fraudster and the victim is believed to be Vietnamese by providing the Telegram username “BuiDuPh”, with the display name “Bui Duy Phong” ”.

It seems that the two sides reached an agreement after an exchange on Telegram and the attacker agreed to refund the wrongly transferred money to the victim.

Based on on-chain data, the victim's wallet began receiving funds at 3:00 p.m. on May 10 (Vietnam Time).

After that, a series of different wallet addresses sent ETH to the victim. Thieves used Coin Mixer to transfer ETH to hide their identity.

During the negotiations, it seemed that there was a significant step forward when the perpetrator returned all 22,960 ETH, equivalent to 68 million USD worth of 1,155 WBTC, that was previously mistakenly transferred. Although the victim was allowed to keep 10% of the initially mistakenly transferred amount as a bug bounty, it seems that the attacker decided to completely end the incident by refunding 100% of the amount.

The 229,960 ETH refund process took more than 10 hours to transfer $68 million worth of ETH back to the victim.
