The $400 million FTX hacker received messages from ETH transactions with money laundering advice.
Hacker Gets Strange Message
The hacker who stole bitcoin valued at $400 million from the shutdown digital asset exchange FTX has received transactions with instructions on how to launder the stolen monies.
Conor Grogan, a director at Coinbase, revealed the information via Twitter. Earlier this month, he also revealed unreported transactions made from FTX creator Sam Bankman-wallet Fried’s in a Twitter thread.
The blockchains of Avalanche, BSC, Arbitrum, and Polygon all saw the transfer of millions of dollars in before undisclosed cash.
Conor Grogan observed transactions with traces of Ethereum sent to the hacker’s wallet (ETH). Further analysis revealed that these transactions had a block explorer viewable public message intended for the cybercriminal.
As stated in the transaction message:
“Hello. Bro, don’t use ChipMixer, it’s not an anonymous mixer enough. Your bitcoins are already tracker after ChipMixer. It is better to use less popular mixers, but more private ones. I can tell to you some info about that.”
A mixer, referred to as a tumbler, is a service that enables users to mix their digital assets with those of others to hide the source of their content. Because of this, it is challenging for the authorities to track the flow of the stolen money.
People who engage in unlawful activity use mixers to launder their illicit funds. Users of the dark web sector also favor these services.
$400 Million FTX Hack
The $400 million attack happened soon after FTX announced its bankruptcy on November 12th, and the US Department of Justice is currently looking into it (DoJ). Large sums of Bitcoin (BTC), Ether (ETH), and other cryptocurrencies were taken from the cryptocurrency exchange during the cyberattack.
Former CEO Sam Bankman Fried had a number of suspects at the time who might have been responsible for the breach. But, later research by digital forensic specialists suggested that the attack might have been a thought-out inside job.
The Department of Justice’s National Cryptocurrency Enforcement Team, a specialist division, is attempting to track down the perpetrators of the heist.
