Bybit filed a civil lawsuit in Washington D.C. against North Korea and its Lazarus Group over a $1.5 billion crypto theft, the exchange said Friday. A federal judge granted a preliminary injunction freezing identified stolen assets while the case proceeds.
The complaint, lodged in the U.S. District Court for the District of Columbia, names North Korea's Reconnaissance General Bureau and the Lazarus Group as defendants. Bybit also named unknown individuals and entities that hold or moved the stolen cryptocurrency, identified as John Doe defendants. That approach is standard in cyber cases: on-chain activity can be traced, though the real-world identities of wallet controllers remain unclear.
The preliminary injunction bars transfers or depletion of identified stolen crypto during litigation. The court found Bybit had demonstrated a likelihood of success on the merits, language that strengthens a plaintiff's ability to maintain asset freezes through discovery, the exchange said. A judge earlier described the incident in a temporary restraining order as "one of the largest cryptocurrency thefts in history," according to Bybit.
Bybit positioned the civil case as complementary to the ongoing criminal investigation led by the FBI and other agencies. The exchange said it has been sharing blockchain intelligence and investigative findings with law enforcement. Criminal probes can take years and prioritize attribution and prosecution. Civil proceedings provide another route to asset preservation, securing funds that might otherwise be laundered or dispersed across jurisdictions.
Ben Zhou, co-founder and CEO of Bybit, said the exchange's priorities remain unchanged: protecting users and recovering funds while holding responsible parties accountable. Zhou argued the alleged Lazarus operation was not merely an attack on Bybit but an assault on broader industry trust. The firm has worked closely with investigators, exchanges, regulators, law enforcement, and now the courts.
Since the February 2025 incident, Bybit said it has worked with blockchain analysis firms, exchanges, custodians, and international law enforcement to trace stolen assets and cut off laundering routes. The exchange reported recovering roughly $48.4 million in stolen cryptocurrency to date and said it has helped freeze more than $30.5 million across over 28 exchanges and custody providers, with those assets pending further legal and investigative processes.
Bybit also pointed to enforcement actions that align with wider efforts to dismantle laundering channels allegedly used after the hack. German authorities took down the crypto exchange eXch. German and Swiss authorities disrupted operations tied to the service cryptomixer.io.
Market observers have increasingly warned that large-scale crypto thefts–particularly those attributed to sophisticated, state-backed groups–pose a systemic risk that extends beyond individual platforms. High-value hacks can test liquidity at exchanges and strain risk controls across custody providers. Compliance often tightens as funds attempt to traverse centralized and decentralized venues.
Bybit said it intends to seek additional judicial relief as the case progresses. Zhou said the real test comes after a crisis, emphasizing that trust must be rebuilt through sustained security upgrades and continuous cooperation with industry partners and investigators.
The civil proceedings remain ongoing. Bybit said it will continue working with relevant authorities and plans to disclose updates to the extent permitted by the court.
