A Whale Loses 55 Million DAI in a Phishing Scam

On August 20, a cryptocurrency wallet user signed an unverified transaction, resulting in the loss of 55.47 million Dai (DAI) due to a phishing attack. After realizing the mistake, the user attempted to withdraw the funds to a new address. However, the transaction failed because the wallet’s ownership had already been changed.

The attacker withdrew $55 million from the victim’s wallet. Blockchain analytics firm Lookonchain warned that the attacker had transferred ownership to a newly created address and withdrawn all the digital assets from the platform. Notably, the attacker exchanged 27.5 million DAI for 10,625 Ether (ETH).

The company advised users not to sign any transactions of unknown origin and always to double-check before confirming anything requiring a signature.

Phishing is a form of fraud in which attackers deceive victims into installing fake software or signing malicious transactions to steal digital assets. They attempt to trick victims into revealing their private keys, personal information, or granting access to their wallets.

In the first half of 2024, phishing attacks caused nearly half a billion dollars in losses. On July 3, blockchain security firm CertiK reported that nearly $498 million had been lost to phishing attacks within the cryptocurrency space. CertiK co-founder Ronghu Gu emphasized the importance of multi-factor authentication methods such as two-factor authentication and security keys.
