HA NOI (Biz Hub) — Malware and distributed denial-of-service (DDoS) attacks will continue to threaten network security in 2015, says Viet Nam's security firm Bkav.

It notes that hackers will continue to spread links infected with viruses on social networks. Spy software and malware that attack on purpose will become more dangerous as they can change depending on the targets. Hackers will start with backdoor penetration of computers of victims to collect information about the users and systems. After the data is sent to servers, it will be exploited, analysed and selected to update malicious software with customised function for every victim. This sophisticated attack will be a target method of new-generation spyware.

The company recommends that users should install anti-virus software on mobile phones and computers.

According to Bkav, DDoS attacks created a lot of trouble for network administrators in 2014, adding that it will continue to happen this year, when many enterprises and government agencies are depending on the Internet.

The company has also warned about cyber attacks in the "Internet of Things" era. Internet-connected mobile devices are projected to break out from 2015, with the participation of many global technology companies. Attacks on the devices will be an unavoidable trend, especially when the users are not in the habit of being concerned about their security.

Last year, computer users in Viet Nam suffered an average loss of VND1.2 million (US$57) per person. With 6.98 million computers, as mentioned in the 2014 ICT White Book, Vietnamese users lost a total of more than VND8,500 billion ($404.7 million). — VNS
