The consequence, according to the antivirus company, is a high number of unprotected routers. Although vulnerabilities are known to manufacturers, patches have never been installed by most users. The scenario favors cyber attacks that stop targeting phones and computers to focus directly on the home router, such as VPNFilter, which has infected more than 700,000 devices worldwide this month.
Deprecated routers are vulnerable to malware such as VPNFilter, which installs on the router using known device failures. As the user has rarely downloaded and installed the patch update, the threat is free to exploit the security breach and to enter the network. With this type of strategy, hackers can intercept the complete user traffic and steal information that is not encrypted.
In the case of VPNFilter, the malware always attempts to openly encrypt the websites, increasing the attack coverage. The security reports indicate that the virus could have invaded even the bank account of the victims. The malware has touched people in 54 countries, using routers manufactured by Asus, D-Link, Huawei, Linksys, Mikrotik, Netgear, Ubiquiti, TP-Link and ZTE.
Another option is to adopt smart mesh type routers that receive automatic updates and can be managed by a mobile application. This alternative, however, requires a larger investment. The TP-Link Deco M5, for example, has a price of about 1,500 reais in e-commerce in Brazil.
