Vu Ngoc Son, Bkav’s Vice Chairman, said the malware disguises itself as anti-virus software after breaking into computers, adding that the group has issued warnings to users to download a free malware scan tool via the link: bkav.com.vn/scanspyware to detect the spyware.

“It’s unnecessary to install the software. Upon discovering any malware, administrators should immediately alert relevant agencies to scan the whole computer system. Once the malware is in the system, it can collect passwords and enable hackers to control computers from afar,” said Son.

Vietnam Airlines’ computer systems at Tan Son Nhat and Noi Bai international airports were hacked on July 29. Screens showing Vietnam Airlines flight information at the two airports were changed and the data of more than 400,000 passengers were leaked to the internet.
