21st Feb 20 Unauthorized Transactions Update: All Funds Safe, Restored and Services Reinstated - All Services Back in Action at Coinhako

We are glad to share that Coinhako is back to full operational capacity, with added security to our wallets, user accounts and the rest of the platform. Our overall plan against the sophisticated and coordinated attack on specific user accounts at Coinhako — first detected on 21st Feb 2020 — was effective and only fewer than 20 users were affected; all of whom have been fully reimbursed.

Coinhako remains operational and no cryptocurrency keys were accessed.

During the recovery period, Coinhako also maintained a high level of communication with users, by providing daily updates via our Telegram channel


As we value the trust our users have in our platform, we would like to take the opportunity to share with you in detail about the situation. Here is a timeline of the key events during the past few days.

21 Feb 2020

Upon the first unauthorised withdrawals being made, our system detected a discrepancy in the account balances. As part of our risk management process for cryptocurrency transaction anomalies, our wallets were entered into a network maintenance mode, temporarily disabling the "Send" function.

This allowed our team to reconcile all transactions against the blockchain transactions and known-good order data backups to verify balances.

As part of this process, the unauthorised cryptocurrency transactions were identified.

All other cryptocurrency services and fiat deposit and withdrawal services on Coinhako remained fully functional; Access remained accessible throughout.

23 Feb 2020

An initial consensus by the security team was made that all services would be safe to return to full operational capacity by 26 Feb 2020.

A trade fee discount code was distributed to all Coinhako users for all cryptocurrency trading pairs (Buy, Sell and Swap cryptocurrencies), allowing them to convert their cryptocurrencies back to fiat–where users could request for direct bank transfer– at a cheaper rate and vice versa.

25 Feb 2020

Additional precautionary measures were identified by the security team to ensure maximum security of our platform upon our return to full operational capacity.

  1. All user accounts were made to do a password reset.
  2. All user accounts with enabled Two-Factor Authentication (2FA) were made to do a 2FA reset.

Additional days were added to the initial re-opening consensus, shared on 23 Feb 2020.

26 Feb 2020

All affected users were fully reimbursed the amounts of any unauthorized transaction from this incident.

Our team continued to work around the clock to enhance our security measures and clear the backlog of ongoing 2FA resets.

27 Feb 2020

Our team nears full completion of our recovery plan and commenced on final works to ensure a safe return to full operational capacity.

28 Feb 2020

'Send' for the first batch of cryptocurrencies – Bitcoin (BTC), Bitcoin Cash (BCH), Ethereum (ETH) – was re-opened, but with added security measures.

These temporary security measures that were put in place would allow us to monitor larger cryptocurrency transaction amounts more closely.

29 Feb 2020

'Send' for the second batch of cryptocurrencies – Tether (USDT), True USD (TUSD) and USD Coin (USDC) – was re-opened, with the added security measures to monitor larger cryptocurrency transaction amounts more closely.

The ‘Send’ function for all cryptocurrencies was re-enabled and Coinhako returned to full operational capacity.

We would also like to clarify that throughout the entirety of the recovery process, we managed to be remain fully operational and user access to funds stayed open; Trading services such as the ‘Buy’, ‘Sell’, and ‘Swap’, as well as ‘Receive’ for cryptocurrencies were still available. Bank transfers and all other fiat – Singapore Dollars (SGD), Vietnamese Dong (VND), and Indonesian Rupiah (IDR) – services were not halted at any point in time.

While additional security measures are still in progress, we are confident that we have taken the necessary steps to allow us to re-enable all our services for everyone.
