Zero to Mobile Pentester

Zero to Mobile Pentester is an 83-page, hands-on Android & iOS penetration testing guide built by Brut Security — a complete methodology, not a theory dump. It takes you from "I've never touched mobile security" to running real exploits against real vulnerable apps, writing up findings the way a professional pentester would hand them to a client.

Why buy it

Most cybersecurity training treats mobile as an afterthought — a single chapter bolted onto a web app pentesting course. But the apps actually holding people's money, health records, and personal data today are mobile. If you can't test a mobile app, you're missing one of the highest-demand, least-saturated skill sets in offensive security right now.

This guide closes that gap without wasting your time:

• No filler. Every technique comes with the exact commands, not vague explanations.
• You actually do the exploits. Every chapter includes a hands-on lab against a real, free, legally practiceable vulnerable app — InsecureBankv2, Sieve, AGoat, DVIA. You bypass a login screen, decrypt a hardcoded key, and defeat SSL pinning yourself, on your own machine, before you ever touch a client engagement.
• It doesn't stop at exploitation. You finish knowing how to score a finding with CVSS and write a report a client will actually act on — the part most guides skip entirely and most beginners have no idea how to do.
• Beginner to advanced in one book. Start with zero mobile security background, end with the same SSL pinning bypass techniques (Xamarin/.NET, Flutter) that trip up testers with years of experience.

What's inside (83 pages)

• Android & iOS architecture — APK/IPA internals, sandboxing, how each platform actually enforces security
• Building your own lab — rooted Android + jailbroken iOS, from scratch
• Static analysis — JADX, Apktool, MobSF, class-dump
• Dynamic analysis & IPC exploitation — Drozer, exploited live against a real vulnerable banking app
• Runtime instrumentation — Frida & Objection, writing your own hooks
• SSL pinning bypass — including Xamarin/.NET and Flutter cases most guides never cover
• Vulnerability deep-dives — insecure storage, broken authentication, weak cryptography, anti-tampering bypass — all mapped to OWASP MASVS
• Professional reporting — CVSS scoring, a full worked finding write-up, client-ready structure
• Bonus appendices — Android & iOS security checklists, a vulnerable-app practice directory, a tool command cheat-sheet, and a glossary

Who it's for

Anyone starting in offensive security who wants a real, employable skill — students, junior pentesters, bug bounty hunters expanding into mobile scope, and web app testers who keep getting asked "can you test our app too?" and want to actually say yes.
