Mobile Security

Secure mobile applications. Learn to pentest Android and iOS apps, reverse engineer binaries, and implement runtime protections.

Mobile apps are high-value targets. This advanced course teaches you to audit the security of Android (APK) and iOS (IPA) applications. You will learn to reverse engineer compiled code using tools like Frida and Hopper. Master intercepting traffic to find API vulnerabilities, identify insecure data storage, and bypass jailbreak/root detection mechanisms. We also cover implementing code obfuscation and certificate pinning to harden your own applications against attackers.

Mobile Security FAQs

Hard?

Very technical; requires reading assembly/bytecode.

Jailbreak needed?

Yes, for iOS analysis a jailbroken device helps.

Tools free?

Most are open source (Frida, MobSF, Jadx).

Prevent piracy?

Hardening makes piracy harder, not impossible.
