TRM Labs and Chainalysis attributed this week's approximately $6.4 billion Binance hack to TraderTraitor, a North Korean hacking group. Chainalysis said investigators observed stolen Binance funds mixing with proceeds from last month's Bitget exploit, previously attributed to North Korean actors. North Korea has previously rejected hacking allegations. Binance said on Friday that the exchange had reserved more than $6.34 billion of company funds to cover losses, including $5 billion already held in the stolen tokens. Binance estimated that about $3 billion in assets had been frozen.
