Most cybersecurity certifications are multiple-choice exams. You memorize acronyms, pass the test, and receive a credential that tells employers you studied for a few weeks.

The CAED (Certified Android Exploit Developer) certification from Mobile Hacking Lab is different. It is a practical exam. You are given a target environment and you have to find and exploit real vulnerabilities in Android native code — the same skills you need to find CVEs in production apps.

This guide covers everything you need to know about CAED: what it tests, how it compares to other mobile security certifications, and how to prepare.

What Is CAED?

CAED is a hands-on practical certification focused specifically on Android exploit development — the skill of finding memory corruption vulnerabilities in Android native code and developing working exploits.

It is offered by Mobile Hacking Lab, the same platform behind the Android Userland Fuzzing & Exploitation (AFE) course. The certification is the direct assessment of the skills taught in that course.

How CAED Compares to Other Mobile Security Certifications

Several certifications claim to cover mobile security. Here is how they actually compare:

The key differentiator: CAED is one of the few certifications that actually tests exploit development. Passing it demonstrates you can do the thing — not that you can describe what the thing is.

Who Should Pursue CAED?

CAED is appropriate for:

• Security researchers who want to move from application-layer testing into native code vulnerability research
• Bug bounty hunters targeting Android vendors and OEMs that pay top dollar for native code bugs
• Red team operators at security firms that perform full-scope mobile assessments
• Software developers building security-critical Android components who need to understand how their code gets exploited

It is not the right starting point for beginners. You need solid Android security foundations, C/C++ literacy, and experience with memory debugging before attempting CAED.

Prerequisites: What You Need to Know First

Before attempting CAED, you should be comfortable with:

1. Android architecture — Process model, JNI, how native libraries are loaded
2. Static analysis — Reading decompiled Java with JADX, analyzing ELF binaries with Ghidra
3. Dynamic analysis — Frida, Objection, GDB for native debugging
4. C programming — You do not need to write complex C, but you must be able to read and understand it fluently
5. Memory concepts — Stack vs heap, buffer overflows, use-after-free, how allocators work
6. Android mitigations — What ASLR, NX/DEP, stack canaries, RELRO, and PIE are and how each affects exploitation

If any of these feel unfamiliar, start with the free course on Mobile Hacking Lab, work through the application-layer content, then move into the AFE course as direct CAED preparation.

The Preparation Path

Step 1: Mobile Hacking Lab Free Course (1–2 weeks)

Build your Android security foundation. The free course covers the environment setup and concepts you need before touching native code. See our full guide to free mobile hacking courses.

Step 2: Android Userland Fuzzing & Exploitation (AFE) Course (4–8 weeks)

The AFE course is the direct preparation path for CAED. It covers:

• Setting up AFL++ for Android native library fuzzing
• Writing effective fuzzing harnesses
• Crash triage and root cause analysis with GDB
• Exploit development: heap exploitation, ROP chains, bypassing ASLR
• Real CVE walkthrough from initial crash to documented exploit

Do not skip steps in this course. The technical progression is deliberate.

Step 3: Independent Practice (2–4 weeks)

After completing AFE, practice independently on real Android targets before attempting the exam:

• Download apps from the Play Store and analyze their native libraries
• Set up AFL++ on real .so files from production apps
• Analyze published Android CVEs — read the patch, reproduce the crash, understand the root cause
• Write a full technical report for at least one vulnerability you discovered or reproduced

What the Exam Looks Like

CAED is a time-limited practical assessment. You are given an Android environment with target native libraries and must:

1. Identify the attack surface in the provided target
2. Use fuzzing or manual analysis to discover vulnerabilities
3. Develop a working proof-of-concept exploit
4. Document the vulnerability and exploitation technique in a professional report

There are no multiple-choice questions. If you can exploit it, you pass. If you cannot, you do not.

Why CAED Matters for Your Career

The mobile security job market in 2026 has a significant skill gap at the native code level. Most candidates can do application-layer pentesting. Very few can do exploit development on Android native code.

This is the skill that gets you:

• High-severity Android vulnerability research positions at security vendors
• Bug bounty payouts at the top tier — critical Android platform vulnerabilities pay $150,000+ through Google’s Android Security Rewards program
• Red team roles that require full-scope mobile compromise capabilities

CAED is one of the few credentials that directly signals this rare capability. A hiring manager at a serious mobile security firm knows what it takes to pass it.
