The crypto thief responsible for the Coinbase data breach has also resorted to publicly mocking blockchain detectives while laundering tens of millions of dollars in stolen cryptocurrency. The attacker recently exchanged 8,697 ETH for 22 million DAI, a dollar-pegged stablecoin.

Those funds were converted into an additional $23 million in DAI using a different address believed to be part of the same operation, which had received 9,081 ETH via THORChain.

The transactions identified by PeckShield highlight an attempt to funnel the illegal funds into stable assets as part of a broader money laundering strategy. The attacker’s decision to insult ZachXBT, a well-known crypto detective, by sending a meme video link and an insult through Ethereum’s transaction message field makes this case particularly egregious.

After the simple message, “L bozo,” a video of NBA legend James Worthy smoking a cigar followed. According to ZachXBT, who shared details about the taunt on his Telegram channel, blockchain evidence links the sender of this message to the same organization responsible for the breach that exposed tens of thousands of Coinbase users.

These recent transactions and taunts occurred following Coinbase’s disclosure that the hack affected at least 69,400 users and stemmed from a campaign that began in December 2024 but went undetected until May 2025, based on disclosures submitted to the Attorney General in Maine.
