In a subsequent tweet, the PeckShield team noted that around 3250 Ethers valued at $9.5 million were stolen from a whale wallet on the Ronin network. The funds were later channeled to Ethereum accounts through Tornado Cash Mixer.

Based on the Peckshield report, the analyst argued that the hackers preferred the Tornado Cash Mixers due to their complexity in tracing the movement of funds. Unlike other wallets the Tornado Cash Mixer has anonymity features that hide the source of funds.


Sky Mavis’ boss argued that the hacking incident had minimal impact on the operation of the Ronin network. He added that the attack did not interfere with his personal accounts.
