Flight information display screens at Noi Bai International Airport in Hanoi suffered glitches on Monday, but terminal managers quickly ruled out hacking.
Instead of displaying flight information, some of the monitors at the check-in counters at the Terminal T1 showed bands of colors and codes at around 2:00 pm.
Many passengers took photos of the erroneous screens and shared on social networks, believing that the airport system had been compromised by hackers again.
Some eye-witnesses said that staff at the check-in counters of the national flag carrier Vietnam Airlines had passengers conduct the check-in procedure manually.
Thirty minutes later, the screens had returned to normal.
Vu The Phiet, director of the Noi Bai International Airport, told Tuoi Tre (Youth) newspaper that the incident was only a technical issue, rather than a hack.
“There were some issues in the switch system transferring data to some of the screens in VNA’s check-in counters, which is to blame for the glitches,” Phiet explained, adding that the problem had been solved.
Vietnam Airlines also said that the issue was due to the airport’s devices, confirming that the carrier’s system was operating normally.
Previously, Noi Bai and the Ho Chi Minh City-based Tan Son Nhat International Airport were struck allegedly by Chinese hackers.
Some flight information screens were compromised last month and displayed offensive messages about Vietnam and the Philippines, along with distorted information about the East Vietnam Sea.
The Da Nang International Airport, the largest of its kind in central Vietnam, did not have its’ flight announcement system compromised, but the computer did experienced repeated glitches.
Data of some 411,000 VIP passengers of Vietnam Airlines had been threatened.
