How to Detect Remote Code Execution (RCE) Attacks in Android & iOS Apps Using AI
This Knowledge Base article describes how to use Appdome’s AI/ML in your CI/CD pipeline to continuously deliver plugins that Detect Remote Code Execution (RCE) in Mobile apps.
What Is a Remote Code Execution (RCE) Attack?
A Remote Code Execution (RCE) attack enables attackers to execute arbitrary commands on a target system by exploiting vulnerabilities in input validation or other weak points in the app. Techniques such as shellcode injection allow attackers to manipulate memory, escalate privileges, and gain control over app functions and user data. AI-based tools now assist attackers in identifying vulnerabilities and automating RCE attack chains, increasing risks to application integrity, data security, and user privacy. Defending against RCE attacks is crucial to comply with standards like PCI DSS, ensuring data remains secure and unmodified by unauthorized code.
How Appdome Protects Mobile Apps Against Remote Code Execution (RCE) Attacks?
Appdome’s dynamic Detect Remote Code Execution (RCE) Attack plugin monitors for unauthorized code execution attempts within mobile applications. It analyzes incoming data for patterns indicative of RCE exploits, such as deserialization attacks, buffer overflows, and command injections. The plugin also detects the presence of known exploitation tools and frameworks, including Metasploit and Cobalt Strike, which are often used to facilitate RCE attacks. Upon detection, it can automatically disable specific app functionalities, log the event, or terminate the session, ensuring the app operates securely and maintains its integrity. Mobile developers can leverage Appdome’s Threat-Events™ to collect detailed data on RCE attacks and tailor in-app responses based on detected threats.
