1.2 million computers in Vietnam might have been infected with a destructive virus called W32.XFileUSB
|
When a computer is infected with this virus, once the user connects to his USB device, the virus will delete the files on the USB and replace them with fake files containing malware.
When the virus-infected USB is inserted into another computer, the virus will continue to spread.
Bkav Vice Chairman Vu Ngoc Son said that data loss is a common security breach in Vietnam, the virus can not only cause data loss but also take control of the computers to download more malware to spy on the computers or launch a targeted attack.
Bkav estimated that computer viruses caused economic losses of up to VND12.3 trillion, or US$541.2 million, last year, up 18.27 percent from VND10.4 trillion (US$457.6 million) in 2016 and more than 41 percent higher than 2015’s figure.
