United States court records unsealed on Thursday show that a federal judge backed crypto exchange Bybits effort to trace assets stolen in the $1.5 billion North Korea-linked hack by granting the company expedited discovery.
According to the records, Bybit filed the lawsuit under seal on June 18 against North Korea, its Reconnaissance General Bureau, the Lazarus Group and 20 unidentified defendants. The court granted Bybits request for expedited discovery on June 19.
The discovery authority gives Bybit a practical route to identify alleged intermediaries and pursue a small portion of stolen assets that remains traceable, rather than relying solely on a judgment against North Korea.
In its complaint, Bybit alleged that some traceable assets reached exchanges operating or maintaining infrastructure in the US. The company sought account-holder identities, balances and transaction histories, saying certain platforms had indicated they would cooperate after receiving a court order.
Bybit says 90% of stolen funds became untraceable
Bybit also obtained a temporary restraining order on June 19 preventing the unidentified defendants from transferring certain traceable assets. The court renewed the order on July 16 and partially granted Bybits request for a preliminary injunction on July 30. Some exhibits and other records remain sealed.
As of the June 18 filing, Bybit said 90.2% of the stolen assets had become untraceable after passing through mixers, cross-chain bridges and over-the-counter dealers. The remaining 9.8% had been traced to identifiable wallets, including 5.3% of the total, about $75.5 million, that had been frozen or recovered.
The figures mark a sharp drop from more than a year ago, when Bybit CEO Ben Zhou said at the time that 68.57% of the funds remained traceable.

The hack occurred on Feb. 21, 2025, after attackers compromised Safe Wallets infrastructure. Forensic investigators said compromised credentials belonging to a Safe developer allowed the attackers to inject malicious code into its cloud infrastructure. The FBI attributed the theft to North Korea on Feb. 26, 2025.
The lawsuit shows that Bybit is seeking the return of the stolen assets, approximately $1.5 billion in compensatory damages, punitive damages and treble damages under the US Racketeer Influenced and Corrupt Organizations Act.
