Binance CFO Kaiser Ng Leaves a Week After $6.3 Billion Hack; Justin Yek Takes Over
Binance said chief financial officer Kaiser Ng is leaving after more than five years, with Justin Yek taking over. The change comes just over a week after hackers stole $6.3 billion from the exchange, a theft Binance and the FBI blamed on the North Korean group TraderTraitor.
Binance said on Saturday that chief financial officer Kaiser Ng is leaving the world’s largest cryptocurrency exchange, just over a week after hackers stole $6.3 billion from its users in the largest cryptocurrency theft on record.
Ng will be replaced by Justin Yek, a longtime finance executive who was most recently vice president of finance at the payments firm Airwallex, according to Reuters. Ng had been Binance’s finance chief since January 2022 and previously held the same job at rival exchange Kraken for about five years.

Co-chief executive Yi He said in a statement that Ng had decided to “pursue a new venture after more than five years at Binance, with a transition plan implemented over the last half year.” The statement, first reported by Bloomberg and carried by TechCrunch and Reuters, does not mention the hack, and the company has not said when Ng’s departure takes effect or what venture he is joining.
The hack and the fallout
The theft hit Binance’s hot wallets on Oct. 29. Binance and the FBI blamed the intrusion on TraderTraitor, a North Korean hacking group, an allegation Pyongyang has denied, according to Reuters. Binance has said the attack began months earlier, with malware hidden in software downloads and fake job offers aimed at its engineers.

Binance froze withdrawals for several days after the theft. Once accounts were unfrozen, users withdrew a net $3.6 billion in the first few hours, according to TechCrunch. Binance has said it set aside around $6.34 billion of company funds to cover the stolen money and promised that customers would not bear the loss. “Binance will bear the financial impact of the stolen funds. These losses will not be passed on to users,” the company said.

On Nov. 5, Binance’s co-chief executive said asset outflows had normalized and the company was in strong health after the heist. Yek now takes charge of Binance’s finances as the exchange continues to deal with the aftermath, including the reimbursement of affected users.
