Security researchers have been warning about an ongoing malware campaign hijacking Internet routers to distribute Android banking malware that steals users’ sensitive information, login credentials and the secret code for two-factor authentication.
In order to trick victims into installing the Android malware, dubbed Roaming Mantis, hackers have been hijacking DNS settings on vulnerable and poorly secured routers.
DNS hijacking attack allows hackers to intercept traffic, inject rogue ads on web-pages and redirect users to phishing pages designed to trick them into sharing their sensitive information like login credentials, bank account details, and more.
Hijacking routers’ DNS for a malicious purpose is not new. Previously we reported about widespread DNSChanger and Switcher—both the malware worked by changing the DNS settings of the wireless routers to redirect traffic to malicious websites controlled by attackers.
Discovered by security researchers at Kaspersky Lab, the new malware campaign has primarily been targeting users in Asian countries, including South Korea, China Bangladesh, and Japan, since February this year.
Once modified, the rogue DNS settings configured by hackers redirect victims to fake versions of legitimate websites they try to visit and displays a pop-up warning message, which says—”To better experience the browsing, update to the latest chrome version.”
