Mobile Security
Mobile application security encompasses the unique attack surface of iOS and Android applications, including insecure local data storage, weak transport layer protection, insufficient binary protections, and client-side injection vulnerabilities. The OWASP Mobile Top 10 highlights risks such as improper platform usage, insecure data storage, insecure communication, insecure authentication, insufficient cryptography, and code tampering. Mobile apps face threats that web applications do not: reverse engineering of client-side code, certificate pinning bypass, inter-process communication attacks, and exploitation of platform-specific features like deep links, content providers, and keychain storage. Tools like Frida, objection, MobSF, and Jadx enable dynamic instrumentation and static analysis of mobile binaries, while proxy tools allow interception of API traffic for server-side testing.

Frequently Asked Questions
- What is the OWASP Mobile Top 10?
- The OWASP Mobile Top 10 covers the most critical mobile application security risks: Improper Credential Usage, Inadequate Supply Chain Security, Insecure Authentication/Authorization, Insufficient Input/Output Validation, Insecure Communication, Inadequate Privacy Controls, Insufficient Binary Protections, Security Misconfiguration, Insecure Data Storage, and Insufficient Cryptography.
- What tools are used for mobile app security testing?
- Essential tools include Frida and objection for dynamic instrumentation, MobSF for automated static and dynamic analysis, Jadx and apktool for Android reverse engineering, Hopper and Ghidra for iOS binary analysis, and proxy tools like Burp Suite or mitmproxy for intercepting API traffic with certificate pinning bypass.
- How is mobile security testing different from web testing?
- Mobile testing adds client-side concerns: local data storage, binary protections, certificate pinning, inter-app communication, and platform-specific features. You must analyze the compiled binary, not just network traffic. Reverse engineering reveals hardcoded secrets, hidden endpoints, and client-side logic that attackers can manipulate.
