Stolen funds worth $26 million

On-chain data shows that the stolen funds from the platform were worth $26 million in digital assets, including 1,728 ETH, worth around $4.85 million, and 409 BTC valued at $21 million.

The attacker has moved most of the stolen ETH  funds to the Ethereum crypto mixer eXch, according to blockchain security firm PeckShield.

The stolen 409 BTC were dispersed to multiple addresses by the attacker, according to Beosin Alert.

On-chain investigators revealed that part of the stolen fund, precisely 166.1 BTC, was sent to Samourai Wallet to use Coinjoin transactions to obfuscate the transaction trails.

“CoinJoin transactions are a type of transaction where two or more people combine their funds into one transaction in such a way that after the transaction it is unclear who owns which coin,” Evgenii explained.
