Golden Finance reported that the hacker Blockchain Bandit stole 51,000 Ethereum mainly by successfully guessing weak private keys. After being dormant for nearly two years, blockchain investigator ZachXBT stated in a Telegram post on December 30 that all 51,000 Ethereum were transferred from 10 wallet addresses to the multi-signature address '0xC451D542'. These funds were mainly transferred in batches of 5,000 Ethereum between 8:54 pm UTC and 9:18 pm UTC on December 30. Prior to this, the stolen funds had been dormant in these 10 wallet addresses since 51,000 Ethereum were transferred on January 21, 2023. Around the same time, the hacker also transferred 470 Bitcoin.
