Level Up in Android App Hacking
For Pentesters and Bug Bounty Hunters
It's a skill most people never build. That means less competition, more opportunities, and bigger bug bounty payouts for the ones who do. Hands-on reverse engineering and real bug-hunting techniques that grow your career and land high-impact bugs.
Start HackingSound familiar?
You're comfortable dropping a target into Burp and picking it apart. An APK just sits there like a locked box.
You've got a mobile pentest on the calendar and nothing to prep with but random blog posts and half-working Frida scripts.
You can decompile the Java fine. You still can't tell which three lines in ten thousand actually matter.
Every write-up skips straight to the exploit and assumes you already know fundamentals nobody actually taught you.

Your Instructor
Richard
Richard, also known as sambal0x, has spent over a decade hunting bugs and vulnerabilities as a professional pentester, with a spot on the Google Play Security Reward Program's top contributors list and speaking credits at a security conference.
This course has been taken by working Security Consultants, Pentesters, and Android Security Researchers — testers who came in solid on web and left dangerous on Android. Every lesson pairs real vulnerable apps and working proof-of-concepts with the reasoning behind each technique, so you actually understand how Android apps break, not just which tool to run.

What students are saying
"The most systematic Android security course I've seen online."
En He — Android Security Researcher, China
"The course starts with a solid technical foundation and quickly moves into practical techniques."
Chris Moberly — Red Team Leader, Australia
"Each lesson covers the theory thoroughly with source code and APK files to practice with."
Bryan Matthew — Junior Pentester, Indonesia
"Coming from a web testing background and new to Android security, the practical techniques have been super useful."
Martin J. — Security Consultant, New Zealand
"I like the simple vulnerable apps paired with quick, clear PoCs."

Beyond API Testing
Learn to Think Like an Attacker
Hacking Android apps isn't just about APIs — many testers think that's all there is. Once you learn the core concepts through the lens of an attacker, high-impact vulnerabilities become much easier to find.
Look deeper
Understand How Android Apps Actually Work
Real vulnerability-finding starts with understanding the inner workings of Android apps, not just running a scanner and hoping for the best.
Focus your effort
Recognize the Attack Vectors That Matter
Not every corner of an app is worth your time. Learn to zero in on the attack surfaces that actually lead to high-impact findings.
Go hands-on
Master Static and Dynamic Reverse Engineering
Reverse engineer real apps through both static and dynamic analysis, the core technical skill the rest of the course builds on.
