Read reviews, do your research and if an app seems too good to be true, it probably is. Bad apps manage to slip through the cracks from time to time which is why you should always be careful when installing any new app. For additional protection though, you may also want to install one of the best Android antivirus apps.Įven if you only download apps from official sources, there’s still a chance that you may accidentally install a malicious app. While it may be convenient to install an app without going through an official app store like the Google Play Store, this also puts you at risk as you have no idea what its APK installation file may actually contain.Īt the same time, you want to make sure that Google Play Protect is enabled on your Android smartphone as it scans any new apps you install as well as your existing apps for malware. When it comes to the Nexus banking trojan and other Android malware, the first way that you can protect your devices and the data they contain is by not sideloading apps. In the latest version of Nexus, the banking trojan can now erase text messages received on an infected device, stop its 2FA stealer module and periodically update itself by pinging a cybercriminal-controlled command-and-control (C&C) server. Likewise, Nexus also includes a keylogger to steal any passwords a user may type in or autofill on their phone. Victims go to login to their accounts as they normally do but the overlay captures their username and password. For those unfamiliar, these kinds of attacks involve putting an overlay or a fake version on top of a legitimate banking app. The way in which Nexus is able to steal and drain the bank accounts of victims is by performing overlay attacks. However, as The Hacker News (opens in new tab) points out, its creators have included explicit rules that prevent it from being used in the following countries: Azerbaijan, Armenia, Belarus, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Uzbekistan, Ukraine, and Indonesia. Just like with other banking trojans, it’s being distributed using a Malware-as-a-Service model where hackers pay other hackers for access to the malware. The Nexus banking trojan was first discovered in an advertisement on a Russian cybercrime forum which explained that it is a new project which is compatible with Android versions up to Android 13.
