TOKYO: Some ¥6.7 billion (RM247 million) in cryptocurrency has been stolen from a Japanese exchange during a hack, the operator said today.

Osaka-based Tech Bureau said in a statement it had suspended deposits and withdrawals after three types of digital currency disappeared earlier this month. Of the ¥6.7 billion, ¥4.5 billion came from assets deposited by customers.

The exchange was hacked over a period of about two hours until around 7pm (6pm Malaysian time) last Friday, Tech Bureau said. The company detected an abnormality in the system on Monday and found that the currencies had disappeared the following day, it said.

Tech Bureau has asked for ¥5 billionn assistance from a subsidiary of Fisco, a financial services company. The incident took place despite the government stepping up its supervision of the industry after a ¥58 billion theft at another cryptocurrency exchange operator Coincheck in January. - dpa
