Flight information screens at both Noi Bai International irport in Hanoi and Tan Son Nhat International Airport in Ho Chi Minh City were compromised on July 29, displaying offensive messages about Vietnam and the Philippines along with distorted information about the East Sea. The website of national carrier Vietnam Airlines was also attacked by hackers, with the personal data of many frequent fliers exposed on the main page. The hack affected some 100 flights, which were delayed by between 15 minutes and two hours, the Civil Aviation Authority of Vietnam (CAAV) said in a statement after the attack interrupted the airports’ electronic check-in systems.

A day later, the State Bank of Vietnam (SBV) wrote to banks, credit institutions and financial organizations warning them against hackers. It instructed them to review the safety of their networks, especially with respect to online customer service, and to take the necessary steps to secure their IT systems and protect and recover databases if needed. The SBV also ordered them to have technicians monitoring their IT systems constantly and improve oversight to discover attacks immediately.

Most recently, a warning issued by the Vietnam Computer Emergency Response Team (VNCERT) was submitted to all local IT teams, urging them to scan and eliminate four malicious scripts that can compromise and destroy the whole system. Some commercial banks in Vietnam took immediate preventive action by suspending online payments via credit cards, like VietinBank and Techcombank. Others have decided not to suspend the use of credit cards for online transactions, but said they will keep a careful watch on such payments. Sacombank said that all transactions made by the bank’s card holders will be closely monitored.
