The group of hackers known as China 1937CN Team compromised the announcement screen systems at many major airports in Vietnam. The flight information screens at both Noi Bai International Airport in Hanoi and Tan Son Nhat International Airport have been compromised by hackers that displayed offensive messages toward Vietnam and the Philippines. In May 2015 the same group hacked roughly 1,000 Vietnamese websites, including 15 government portals and 50 education sites. In the same period, around 200 websites in the Philippines were attacked by the China 1937 CN Team.”]
