Hi! I'm speedyfriend67 — a curious iOS reverse engineer, creative Swift developer, and bug bounty hunter 🧪. I explore Apple internals, make PoCs, design custom tools, and build security-focused apps from scratch. Always learning, always shipping.
-
🍎 iOS Security Research
- Bug bounties via Apple Security Bounty program
- Reverse engineering with IDA Pro & Ghidra
- Mach-O parsing, No-JIT hooking, kernel fuzzing, and PoCs
-
🧰 iOS App Development
- Building SwiftUI apps for iOS: from IPA signers to UniGram (campus notification app)
- Tools for Mach-O analysis, IPA injection, and APK Runner
- Using ElleKit, zsign-ios, MachOKit, and more
- Writing PoCs for iOS/macOS
- Creating a professional Ghidra-like reverse engineering suite in Rust, Go, and C++ (in the future)
- Designing Swift packages (e.g. gradients, Mach-O utilities)
- UI/UX experimentation with shaders, blur, glassmorphism, and 3D visuals
| Project | Description |
