The hacker behind the data breach targeting Coinbase users mocked blockchain investigator ZachXBT with an onchain message following a major crypto swap.
On May 21, the hacker used Ethereum transaction input data to write “L bozo,” followed by a meme video of NBA player James Worthy smoking a cigar.
The message came after the attacker swapped about $42.5 million from Bitcoin (BTC) to Ether (ETH) via THORChain.
ZachXBT flagged the message on his Telegram channel, linking it to the same entity responsible for the Coinbase data breach affecting at least 69,400 users.

On May 22, blockchain security firm PeckShield reported that the hacker had continued to move funds, swapping 8,697 ETH for 22 million Dai (DAI). A separate but closely linked address, which received 9,081 ETH via THORChain, also converted the assets into 23 million DAI.
