Japanese cryptocurrency trade exchange Zaif has been a recent target of a malicious hacker who has taken off with millions of dollars worth of Bitcoin.
A press announcement was released on the matter. The report states that the exchange faced a security breach and hackers looted 4.5 billion yen from hot wallets belonging to the firm’s users. The hackers also took off with a further ¥2.2 billion yen in funds from the exchange, resulting in a combined loss of ¥6.7 billion yen. This translates to a whopping $59.7 million USD.
The company operating Zaif, Tech Bureau Inc, announced that there was an oversight detected at the beginning of the week. The servers were showing an error, which resulted in the exchange suspending trading.
The firm announced on Twitter that Bitcoin, Monacoin, and Bitcoin Cash deposits and withdrawals had been suspended:
Currently, in addition to BTC and MONA, BCH deposit / withdrawal is suspended due to server failure. We are investigating for recovery. Please refrain from depositing / withdrawing money.
Moreover, settlement by ZaifPayment is also stopped. We’re sorry for the inconvenience.— Zaif – 暗号通貨取引所 (@zaifdotjp) September 17, 2018
The following day, it was discovered that hackers had managed to get into the system and take off with 5,966 Bitcoin. Additional MonaCoin and Bitcoin Cash were also plundered in the attack.
