Binance CFO exits days after record $6.3 billion crypto heist

The latest:

Binance’s chief financial officer Kaiser Ng is leaving the world’s largest cryptocurrency exchange after nearly five years, the company said Saturday, just over a week after hackers drained $6.3 billion from the platform in what ranks as the largest theft of its kind. Co-Chief Executive Officer Yi He said Ng is pursuing a new venture under a transition plan put in place over the previous six months.

Details:

• The successor: Justin Yek takes over as chief financial officer, according to Binance. Yek is a longtime finance executive who most recently served as vice-president of finance at Airwallex, the cross-border payments firm. Binance did not specify when he formally assumes the role or how responsibilities will be divided during the handover.
• The timing: Binance framed the move as planned rather than reactive, saying the transition had been implemented over the last half year. The announcement nonetheless arrived just over a week after the exchange disclosed the breach, placing a leadership change at the top of its finance function in the middle of the response.
• The heist: Binance said hackers stole $6.3 billion in cryptocurrency in a sophisticated attack that unfolded on October 29. The company said the operation began months earlier with the compromise of several employees’ computers, making it a long-running intrusion rather than a single-day breach.
• The method: According to Binance, the attack started with malware hidden inside software downloads and fake job recruitment approaches aimed at its engineers. The exchange has not detailed how many staff accounts were ultimately compromised or how the intruders moved from employee machines to customer funds.
• Customer exposure: Binance said it will fully reimburse affected customers. It has not published a figure for how many account holders were hit, nor a timeline for completing repayments or an accounting of how the reimbursement will be funded.
• The attribution: The FBI has blamed a North Korean hacking group for the theft. Pyongyang denied the allegation. Neither side has made public the evidence underpinning the identification, and no suspects have been named.
• Ng’s record: Ng had served as Binance CFO since January 2022 and spent more than five years at the company overall, Yi He said. He previously worked at rival crypto exchange Kraken, according to his LinkedIn profile. Binance did not name the venture he is moving to.
• The scale: Binance is the world’s biggest cryptocurrency exchange by trading volume, which magnifies the significance of both the record theft and a change at the head of its finance operation. The company has not indicated whether other executive changes are planned.

Between the lines:

Binance’s emphasis that the handover was arranged six months ago is doing specific work: it separates Ng’s exit from an October breach that the company itself says began months earlier. Both timelines overlap, which is why the exchange volunteered the planning detail rather than simply naming a successor. The unanswered question is operational — who signs off on a multibillion-dollar reimbursement while the finance chief changes hands.

What’s next

Watch for Binance to set a reimbursement timeline and customer figures, for Yek’s formal start date, and for the FBI or Binance to publish technical findings supporting the North Korean attribution Pyongyang has rejected.
