Crypto Exchange Coinhako Briefly Halts Withdrawals after Cyberattack
- The exchange has reset passwords for all users, but the ability to withdraw funds would remain restricted.
.One of Asia's largest crypto exchanges has abruptly frozen all clients' withdrawals this week due to a cyberattack. Singapore's fiat-cryptocurrency platform Coinhako was targeted on February 21 in what the company described as a "sophisticated attack."
Before it announced the attack, the exchange said some functions were paused while it underwent "unplanned maintenance."
Coinhako CEO Yusho Liu told CoinDesk that, following the outage, the exchange had reset passwords and two-factor authentication for all users, but the ability to withdraw funds would remain restricted as a "key countermeasure against unauthorized transaction outflows."
A Coinhako spokesman also explained on Telegram that they have detected "a sophisticated and coordinated attack" on specific Coinhako accounts, and thus the exchange has "disabled the send function as a preventive measure."
Security has been an issue for Asian exchanges
The attack, however, only impacted 20 Coinhako users and trading operations, user accounts, and their associated funds/account balances were not at risk at any point during the attack, the exchange confirmed. Several days after the attack, the exchange assured affected customers that they will be reimbursed from its own pocket.
On 21st Feb 2020, our system was quick to detect transactional anomalies. This allowed us to react and keep affected parties low.
