binary-re:dynamic-analysis

What problem does it solve?

Analyzing binary programs manually is time-consuming and error-prone; this skill provides a framework to run binaries, observe their runtime behavior, and collect actionable data through controlled experimentation.

Core Features & Use Cases

• Runtime execution with QEMU user-mode to map behavior across architectures.
• Dynamic tracing with strace-like syscall logs and memory inspections for root-cause analysis.
• Debugger integration using GDB for instruction- and breakpoint-level control.
• Function hooking via Frida to observe or modify runtime behavior without recompilation.
• Use cases include reverse engineering, malware analysis, security research, and debugging complex binary workloads.

Quick Start

1. Install required tools: QEMU, GDB, and Frida.
2. Run a binary under QEMU with tracing: qemu-arm -L <sysroot> -strace ./binary.
3. Attach GDB for deeper debugging: gdb-multiarch ./binary or qemu-arm with -g.
4. Hook functions on the fly with Frida: frida -f ./binary -l hook.js --no-pause.
