What Is FluBot Malware?
FluBot is a kind of malware that only infects Android phones and is disguised as an app. Though it made its first appearance in January 2020, 2022 saw a marked increase in FluBot cases. It has been named after the flu because it spreads quickly and widely. The malware app gives hackers significant control over an infected Android device. It allows them to extract sensitive personal information, such as banking and credit card details.
How Does FluBot Malware Spread?
FluBot can spread in several different ways. The most common vectors are text messages. Targets of the virus receive messages in languages such as German, Polish, and Hungarian. The text message instructs the user to click on a link to track their parcel which is out for delivery. Alternate versions of the message ask users to click on a link to check their voicemail or download an important security update through a phishing link. Once the user clicks on the link, they are redirected to a webpage. Depending on the contents of the message, the webpage either asks the user to download a tracking app for delivery services like FedEx and DHL, a voicemail app, or a security update. Interestingly, the fake security update actually tells users that they’ve been infected with Flubot and that the update will help remove it! If the user agrees, an APK file infected with FluBot is downloaded and installed on their device. During the installation process, the application requests permissions to access contact lists, read and write text messages and initiate phone calls. In other words, the app gains control over an Android device’s most important functions.
