What Is Flubot Malware on Android and How Does It Work?


Android has progressed significantly, to the point where it is now essentially secure out of the box. However, because of the operating system’s ability to sideload applications, the results can be disastrous.


Flubot is one example of banking malware that has taken advantage of the functionality in recent years. So, what exactly is Flubot? What kind of impact can it have on you? And, if you’ve already been infected, what steps can you take to restore security to your device?


What Exactly Is the Flubot Malware?


Known as Flubot, this new Android spyware program is designed to steal financial login and password information from your device.


It also reads your contact list and uses the information it gathers to find additional users to launch the attack on.


What is the impact of Flubot on you?


Flubot malware infects your device through the use of smishing (also known as SMS phishing) in the first place. You will receive an SMS if, for example, a package delivery is scheduled and you are not present. The SMS will include a link that will allow you to track the progress of your delivery.


They tend to use well-known brand names, such as FedEx, to give the impression that the SMS is legitimate.


If you were anticipating a delivery, you are more likely to click on the link to confirm your expectation. And, if you weren’t expecting it, you might find yourself clicking on the link out of curiosity. In contrast to a legitimate tracking link, this one will redirect you to a bogus website that may appear to be affiliated with FedEx or another delivery service.


It will then prompt you to download and install an Android application in order to track the status of your order. The Android application can be installed manually by the user.


Once it has been installed, it will prompt the user to grant permissions that will benefit the malware.


First, it will request access to your contacts, which it will scan and send to the attacker’s server in order to conduct further SMS phishing attacks on your phone. As a result, your contacts may also receive similar messages, allowing the malware to spread.


Following that, it will inform you that it requires your permission to draw over apps and observe the content on your computer. In other words, it will request permission to make the site accessible. When you grant Flubot additional permissions, it is given the ability to operate with the same privileges as a system application.


The malware then begins to monitor your banking app credentials or cryptocurrency account details, which it later employs to steal any funds you have available.


It is important to note that, despite the fact that Flubot is spyware, it has the ability to disable Google Play Protect as well as uninstall other applications.


What Can You Do to Make a Difference?


You may have noticed that some Android security apps, such as F-Secure and Malwarebytes, require you to grant them access to certain permissions. Allowing this permission access to any other app, on the other hand, can be dangerous.


It is only by performing a factory reset on your device that Flubot can be uninstalled in this situation. Consequently, ensure that you have a backup of your critical files.


You can attempt to remove it using the Android Debug Bridge (ADB), but you should avoid doing so unless you are confident in your abilities.


How to Keep Yourself Safe From Flubot


Flubot malware does not take advantage of any security flaws in your Android mobile device. It requires manual access in order to function. Installing apps from the Google Play Store is preferred over sideloading and should be avoided if at all possible.


Even though sideloading has its advantages, you should always check the source of the APK file before downloading it to your phone. Look for Play Store alternatives that you can rely on to get what you need.


In either case, you should avoid clicking on links, regardless of whether they appear to be legitimate. Background research should assist you in determining whether or not you are clicking on a link that you can rely on.


Never forget to learn more about Android permissions and how they work before making a decision on which permissions you should grant.
