DA NANG (Biz Hub) — The central city's information and communications department has issued an alert over a computer virus called Ransomwar, after new viruses affected personal computers of several businesses early this month.

The department said a hacker would send a fake email attached with the virus to users through an agency's email system. The virus then decodes all information of the computer users on the database, blocking their access to the database.

The department said users should not open suspect and strange emails and messages, and should regularly update their anti-virus software programmes.

Experts also said cyber attacks would increase and affect security and business activities, and aid crimes via emails.

The central city has been developing a cyber security programme for more than 600 information technology businesses and 5,000 staff.

Last October, the website of the city's education and training department was hacked. The department needed a week to regain control over its website.

Da Nang launched the city's e-government system in 2014, including a Metropolitan Area Network (MAN), wireless Internet, data centre and a centre for human resource training and research on IT applications, with 1,196 online administrative procedures.

The city is ready to implement 4G LTE (long-term evolution) and the Internet of Things by 2018.

According to IT experts, only a third of the agencies and enterprises in Viet Nam have set regulations for information security, while 57 per cent of the corporations didn't have funding for their information security programme upgrade or development. — VNS
