Click injection is a malicious technique used by hackers to target users of mobile apps on Android, specifically those with in-app advertising. In this type of attack, hackers inject malicious code into the app that causes a large number of ad clicks to be generated each time the app is opened. The goal of this attack is to generate revenue for the attacker by forcing users to view and click on ads without their knowledge or consent. In addition to generating revenue, click injection can also slow down the app, cause battery drain, and even crash the app altogether.
How Click Injection Works
Click injection works by taking advantage of a vulnerability in an app’s code. By injecting malicious code into the app, hackers can create fake ads or links that look like part of the user interface. When clicked, these ads or links redirect users to a website controlled by the hacker. This website may contain malware or be used to gather personal information. Click injection can also be used to gain access to sensitive data stored on the device, such as financial information or login details.
Furthermore, hackers can use click injection to spread malware and ransomware to other users’ devices through malicious links sent via messaging apps or social media platforms. Additionally, click injection can be used to execute other types of attacks including phishing and man-in-the-middle attacks.
It is important to note click injection can be used against any type of mobile app for Android devices, including those available in the Google Play Store. As such, it’s important for users to remain vigilant when downloading apps and to only trust sources they know are legitimate. Additionally, users should keep their device’s operating system up-to-date in order to protect themselves from potential security vulnerabilities.

How to Protect Your App from Click Injection Attacks
Fortunately, there are a few steps developers can take to protect their apps from click injection attacks:
Implement Secure Coding Practices
Use secure coding best practices when developing your apps. This includes proper input validation, data sanitisation and encryption, as well as using strong authentication methods for user accounts.
Monitor the App’s Environment
Regularly monitor your app environment for any suspicious activity or malicious code injections. Scan your app code regularly to ensure it is free from any security vulnerabilities.
Educate Users About Click Injection
Finally, you can educate users about click injection and the risks it poses. Include warnings in your app’s description and provide links to resources where they can learn more about click injection and the steps they need to take to protect themselves.
Frequently Asked Questions
Who is at risk for click injection attacks?
Anyone who uses an Android device and has mobile apps installed is potentially at risk for click injection attacks. This includes those who have apps installed from the Google Play Store, as well as apps downloaded from less-reputable third-party sources.
What types of attacks can be launched using click injection?
Click injection can be used to launch a variety of different attacks, including phishing, man-in-the-middle, and malware/ransomware distribution. It can also be used to gain access to sensitive data stored on the device.
Why is it important to keep my device’s operating system up-to-date?
Keeping your device’s operating system up-to-date ensures any security vulnerabilities are patched, reducing the risk of click injection attacks. Additionally, users should only download apps from trusted sources in order to protect themselves from malicious code injections.
How does anti-malware software help protect against click injection attacks?
Anti-malware software can detect and remove malicious code before it can be used to launch an attack. This provides an additional layer of protection for mobile apps, helping to keep them secure from potential security threats.
What other steps should users take to protect themselves from click injection?
In addition to using anti-malware software, users should also implement strong authentication methods for their user accounts and only download apps from trusted sources. They should also educate themselves about click injection and be aware of the types of attacks that can be launched using this technique.
