Secure your Android app against malware attacks

    With the surge in the use of mobile banking, malware threats are increasingly targeting Android banking and digital wallet apps. As part of the shared responsibility model, Mobile app publishers should protect their apps and users against malware attacks to avoid financial and reputational damage risks.

    How mobile app malware works

    Malware — malicious software designed to steal sensitive data or make fraudulent transactions — predominantly exploits UI functionality offered by mobile apps or operating systems to launch attacks. Common types of mobile malware attacks include:


    Accessibility services abuse

    Accessibility services on Android — such as automation designed for reading text aloud, filling in forms, or clicking buttons — are designed to help users with disabilities interact with their devices. Unfortunately, malware can exploit these services to steal financial data or user credentials as well if the app is not properly protected.


    Screen sharing and recording attacks

    Malware that uses screen sharing and recording can allow an attacker to remotely view and record activity on an infected device. This type of malware often tricks the user into granting escalated permissions, which gives the attacker access to everything from passwords and credit card numbers to private conversations and images.


    UI injection attacks

    Android overlays allow an app to display content on top of another app. These “floating views” can be used for login pop-ups or alerts. However, malware can also use overlays to trick users into clicking on malicious links or granting escalated privileges, allowing attackers to intercept financial data or make fraudulent transactions.


    Keylogging attack

    A keylogger is a type of malware that records all keystrokes typed on the device, including sensitive information like passwords, credit card numbers, and other personal data. The captured data is often transmitted back to a server controlled by the attacker. Malicious keyboards can replace the user's default keyboard entirely, leading to continuous keylogging.
