Binance CFO Kaiser Ng Exits Days After $6.3 Billion Hack

Binance's chief financial officer, Kaiser Ng, is leaving the cryptocurrency exchange, the company said this week, a little more than a week after hackers stole $6.3 billion from Binance users. Justin Yek takes over as CFO immediately, according to a report by Bloomberg cited by TechCrunch.

Here is what account holders and anyone watching the exchange need to know about the timing, the hack, and what happens next.

What happened in the $6.3 billion hack?

Hackers pulled $6.3 billion in cryptocurrency out of Binance in late October 2026, according to TechCrunch. Binance froze withdrawals for several days while it investigated. Binance and the FBI have blamed a North Korean hacking group known as TraderTraitor for the breach, TechCrunch reported. When withdrawals reopened, users pulled a net $3.6 billion from the exchange within the first few hours — a sign of how shaken some account holders were, even after the company said it would make them whole.

Why is the CFO leaving now?

Binance co-CEO Yi He said in a statement, reported by Bloomberg and relayed by TechCrunch, that Ng's departure will let him "pursue a new venture after more than five years at Binance." Yi He also said a transition plan had been "implemented over the last half year" — meaning the move was in motion long before the hack, not a snap decision tied to the breach. Binance has not said Ng's exit is connected to the security failure.

Who replaces Kaiser Ng as CFO?

Justin Yek steps into the CFO role, per the Bloomberg report cited by TechCrunch. No additional detail on Yek's background was provided in the available reporting.

What changes for Binance users Monday morning?

Nothing about account access changes because of the CFO swap. Withdrawals, which were unfrozen after the hack, remain open. Binance has pledged publicly: "Binance will bear the financial impact of the stolen funds. These losses will not be passed on to users." Customers do not need to take any action related to the leadership change itself.

By the numbers

• $6.3 billion — amount stolen from Binance users in the hack, per TechCrunch.
• $3.6 billion — net amount users withdrew in the first few hours after withdrawals resumed.

Is the hack still under investigation?

Yes. Researchers had warned about North Korean hacking tactics years before this breach, according to a separate TechCrunch report dated Nov. 3, 2026. The FBI's attribution to TraderTraitor places the incident inside a pattern of state-linked crypto theft that security researchers have tracked for years, though Binance has not released a full post-mortem publicly as of this report.

What should account holders watch for next?

Binance has not announced further leadership changes beyond the CFO transition. Account holders should watch for any formal findings from Binance's internal review of the breach and for confirmation that reimbursements promised to affected users have been completed. TechCrunch's reporting, sourced to Bloomberg, remains the most current account of both the leadership change and the hack's aftermath.
