Binance announced that Chief Financial Officer Kaiser Ng is leaving his position after more than five years at the company to launch a new venture. It explained that his departure had been planned in advance and that it began implementing a transition plan for his responsibilities about six months ago.

Justin Yik is set to succeed him as CFO.

The departure comes days after the platform’s users were targeted in a hack in which cryptocurrencies worth $6.3 billion were stolen, prompting Binance to suspend withdrawals for several days.

After withdrawals resumed, users recorded net withdrawals of $3.6 billion in the first few hours.

Binance and the U.S. Federal Bureau of Investigation accused a North Korean hacking group known as TraderTraitor of carrying out the attack, while the platform confirmed it would cover all resulting losses.
