The Authority of Information Security under the Ministry of Information and Telecommunications on May 29 warned that more than 500,000 routers and storages in many countries, including Vietnam, have been exposed to VPNFilter virus.

The most vulnerable devices are Internet-connected routers and storages produced by popular brands like Linksys, Mikro Tik, Netgear and TP-Link.

A research by Cisco Talos group run by Cisco showed that VNPFilter is a multi-phrase cyber-espionage virus that can steal information of websites and spy the industrial command domain such as those of power network or industrial infrastructure.

An effected device will be restarted and reset, during which the /var/run/vnpfilterw link will be created.

The authority advised that if users think that their devices have been infected by the virus, they should reset their devices to default mode to erase the malware, while updating the firmware as soon as possible.

Over the past years, the authority has made several warnings of lopes and weaknesses in information security.

Last week, international organisations announced at least 327 security holes could spark attacks to affect Vietnamese users. -VNA
