Vietnam was subject to 134,375 cyber attacks in 2016, up more than four times from the previous year, according to the national center for computer emergency response VNCERT.

Experts said the situation will remain “complicated” this year.

Nguyen Huy Dung, deputy head of the Information Security Department at the information ministry, said attacks will target important control systems including transport infrastructure, finance and banking.

There will also be an increasing risk of attacks through common household equipment such as televisions and refrigerators connected to wireless internet.

Fraudulent activity on social networks will also be common, Dung said.
