HA NOI (Biz Hub) – The Joint Stock Commercial Bank for Foreign Trade of Viet Nam (Vietcombank) on August 16 announced on its official website changes to activation methods of smart OTP services.

The changes to smart OTP services are aimed at improving security after hundreds of Vietnamese dong were reportedly stolen from a customer's Vietcombank account.

Hoang Thi Na Hương, a Vietcombank customer in Ha Noi, said she received notifications of transfer of VND500 million from her Vietcombank account between 11pm on August 3 till 5am the next day, while she was at home.

The bank said on August 15 that it had managed to cancel the last three orders to keep VNĐ300 million in the bank and return the amount to Huong.

Accordingly, customers who have already used smart OTP and wish to continue using the services on their existing devices must re-activate the service via Vietcombank's Internet banking service.

Those who have not registered for smart OTP services or those wanting to change their devices, will have to go to Vietcombank branches to register and get the service activated.

OTP subscribers are encouraged to download the latest smart OTP application from Google Play Store and Apple Store.

Further investigations are ongoing.

Banks also urged customers to be alert against cyber-attacks. — VNS
