Dynamic Link Library (DLL) Injection is a method malicious actors use to insert malicious code into running processes. A dynamic link Library Injection attack could occur when someone injects code into an app’s DLLs to compromise functionality or steal sensitive information.
Dynamic link library injection (DLLI) attacks are common in mobile app security when an attacker gains access to a mobile device and alters the app’s code or configuration files. Device access can be done through various means, such as exploiting vulnerabilities within the operating system or application itself or employing social engineering tactics to trick users into installing malicious apps.
Once an attacker injects their malicious code into an app’s DLLs, they can use it to carry out various malicious tasks such as stealing sensitive information, altering its behavior, and even taking control of the entire device.
To safeguard against dynamic link library injection attacks, app developers should follow secure coding practices such as code signing and encryption, performing regular security audits, and incorporating runtime protection mechanisms that can detect malicious code injection. Mobile device users should also exercise caution when installing apps from untrusted sources and regularly update their devices with the latest software updates and security patches.
