Dr. Vu Quoc Khanh, Vietnam Computer Emergency Response Team (VNCERT) Director, said 1,428 hacked cases were reported in the first nine months of 2013, higher than last year’s total figure.

On average, computers in Vietnam deliver more than 3.33 million spams daily, he said.

Bach Khoa Internetwork Security Centre (BKAV), a leading internet security firm, warns that cell-phone viruses can affect computers. Internet users should be aware of new ways of hacking via laptops and mobile phones, BKAV suggests.

A special event named “Vietnam Information Safety Day” will be launched in Ho Chi Minh City on November 14 and Hanoi on November 21.

A host of activities will take place during the event, including a seminar and an exhibition on information safety and security in a modern society.
