// The Skill Gap

Application-level bugs get found by everyone. The native layer is where the real opportunity is.

Everyone can run MobSF and find hardcoded secrets. The security researchers earning $50K+ bounties are fuzzing native libraries, finding memory corruption in media parsers, and exploiting system services below the Java layer.

This course teaches you to find bugs that others can't.

Fuzz with AFL++, build custom harnesses for Android targets, triage crashes, and develop working exploits. These are the skills that separate app-level testers from vulnerability researchers.

// What You'll Learn

From first fuzzing run
to working exploit.

01
AFL++ Fuzzing
Set up and run AFL++ campaigns against Android native targets. Coverage-guided fuzzing, corpus management, crash deduplication, performance tuning.
Industry-standard fuzzer
02
Custom Harness Development
Build fuzzing harnesses for Android-specific targets. Isolate and instrument native libraries so AFL++ can reach deep code paths.
Targeted fuzzing
03
Crash Triage & Root Cause
Not every crash is exploitable. Triage findings, determine root cause, assess exploitability before investing time in exploit development.
Efficient analysis
04
Exploit Development
Turn confirmed vulnerabilities into working exploits. Memory corruption, heap manipulation, control flow hijacking in Android userland.
Hands-on exploitation
05
Cloud Lab Environment
Everything pre-configured in browser. Fuzzing infrastructure, target applications, debugging tools. No local setup.
Zero hardware required
06
CAED Cert + Mentorship
Certification exam included, unlimited attempts. Plus 1:1 video mentorship with MHL's vulnerability researchers.
Cert + mentorship included

Userland Fuzzing & Exploitation — Course Trailer

Full course overview — ARM64 architecture, Android sandbox internals, and the fuzzing-to-exploit pipeline you'll master hands-on.

Android Sandbox Exploitation

Example lesson — escaping the Android application sandbox through native library fuzzing and memory corruption.

Vulnerability Discovery

Introduction to vulnerability discovery techniques — finding and triaging bugs in Android native code.

// Where This Fits

The Android exploitation
learning path.

Phase 1 — Application Layer

Application Layer

Start with Advanced Android Hacking. Build exploit chains against real app vulnerabilities. Path traversal to device compromise.

Phase 2 — Native Layer (This Course)

Native Layer (This Course)

Fuzz userland components with AFL++. Build harnesses, triage crashes, develop exploits for memory corruption in the native layer.

Phase 3 — Kernel Layer

Kernel Layer

Continue with Kernel Fuzzing. Fuzz kernel drivers, exploit at ring 0, achieve full device compromise.

// Common Questions

Straight answers.

Do I need Advanced Android Hacking first? +
Recommended but not required. Comfortable with Android internals and native code? You can start here.
30 vs 60 vs 90-day access? +
Same course and cert. Duration controls lab access time. Most finish in 30-60 days.
Need my own fuzzing setup? +
No. Everything in cloud labs.
Relevant for bug bounty? +
Directly applicable. Native-layer bugs attract the highest bounties.
Can I bundle this? +
Kernel + Userland saves 45%. Full Chain (AAH + Userland + Kernel) saves 47%. Already own a course? Contact us for upgrade pricing.
