Hackers Target E-Banking Users By Exploiting Router Vulnerabilities To Hijack the DNS
Gabriel Roşu / 6 years ago
There have been reports about critical vulnerabilities in a variety of routers, including Cisco, TP-Link, ASUS, TENDA and Netgear among others, all of which can be found in a normal household.
According to Polish Computer Emergency Response Team (CERT Polska), they have noticed an increase in cyber attack, leading to a cyber attack campaign aimed at Polish e-banking users. The hackers apparently use known router vulnerability that allow attackers to change the router’s DNS configuration remotely. This allegedly is used to lure users to fake bank websites or can perform Man-in-the-Middle attacks.
“After DNS servers settings are changed on a router, all queries from inside the network are forwarded to rogue servers. Obviously the platform of a client device is not an issue, as there is no need for the attackers to install any malicious software at all.” CERT Polska researchers said.
The DNS can be changed and point to a malicious DNS server from the router’s settings, giving the hacker complete control to facilitate interception, inspection and modification to the traffic between the user and the online banking website.
It is said that most of the Banking and E-commerce sites are using HTTPS with SSL encryption, making it impossible to impersonate them without a valid digital certificate issued by a Certificate Authority (CA), but to bypass such limitation cyber criminals are also using the SSL strip technique to spoof digital certificates.
The recommended steps to take in case of such attacks are to change the default username and password for the router, update the router’s firmware to the latest version and disable Remote Administration features in the router’s settings. Another way to notice fake websites is to lay attention to the browser’s address bar and HTTPS indicators.
