Binance, FBI and Secret Service Investigate $6.4 B Hack, Circle and Tether Freeze $1.8 B in Stablecoins

Binance is collaborating with the FBI and the U.S. Secret Service after a hacking incident that stole $6.4 billion from the exchange. Circle’s CEO Jeremy Allaire said the company has frozen roughly $823 million in USDC linked to the attack, while Tether has frozen about $975.1 million in USDT. Blockchain analytics firms TRM Labs and Chainalysis attribute the breach to the North Korean group TraderTraitor, previously tied to the $1.5 billion Bybit hack. The coordinated freeze of more than $1.8 billion in stablecoins demonstrates how issuers can block stolen digital assets before they are moved, aiding law‑enforcement investigations worldwide.
