Binance has appointed Justin Yek as its new chief financial officer, a move that places a finance executive with a background in traditional banking at the head of the world's largest cryptocurrency exchange at a difficult moment. The appointment was announced on Saturday, and it comes weeks after hackers drained an estimated $6.3 billion from the platform.
Yek most recently served as vice president of finance at Airwallex, the cross-border payments company. Before that he spent about nine years in investment banking at Citi and Morgan Stanley. He succeeds Kaiser Ng, who has been CFO since 2022 and is stepping down to pursue a new venture. Ng joined Binance from the exchange Kraken. Co-chief executive Yi He said the transition had been planned over the past half year, meaning the handover was not a direct response to the breach.
The attack took place on October 29. Binance attributes it to North Korean hackers, who used social engineering and malware to target the access held by the company's engineers. The stolen funds were significant in scale, and the exchange has had to show that it can account for and recover them. Stablecoin issuers Tether and Circle froze about $2.5 billion of the stolen assets, which limited how much could be moved on.
Binance says it has replenished 98% of the stolen coins from its reserves and other sources, and that users will not bear the losses. Those figures are central to the company's effort to reassure customers, but the exchange has not made clear how strong its internal controls are, and that question is now part of the scrutiny it faces from customers and regulators alike.
For Yek, the challenge is therefore less a conventional finance brief than a test of trust. He has no prior experience at a crypto exchange and no previous chief financial officer role, which means he will need to establish credibility quickly. The task ahead includes convincing customers and regulators that the platform's assets are secure, and that the reserves backing user funds can withstand a shock of this size.
The episode also reflects a wider concern in corporate finance. Deloitte's Q3 2026 CFO Signals survey found that 50% of finance chiefs cite cybersecurity as their top external concern. Binance's breach places it squarely within that worry, and the new CFO's first months will show whether the company can translate its recovery figures into lasting confidence in its controls.
