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.
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.”
It then downloads the Roaming Mantis malware app masquerading as Chrome browser app for Android, which takes permission to collect device’ account information, manage SMS/MMS and making calls, record audio, control external storage, check packages, work with file systems, draw overlay windows and so on.
If installed, the malicious app overlays all other windows immediately to show a fake warning message (in broken English), which reads, “Account No.exists risks, use after certification.”
Roaming Mantis then starts a local web server on the device and launches the web browser to open a fake version of Google website, asking users to fill up their names and date of births.
To convince users into believing that they are handing over this information to Google itself, the fake page displays users’ Gmail email ID configured on their infected Android device, as shown in the screenshots.
You are advised to ensure your router is running the latest version of the firmware and protected with a strong password.
You should also disable router’s remote administration feature and hardcode a trusted DNS server into the operating system network settings.
