RE 실습 환경 설정

Before any RE, build a safe lab — your secure workbench. It keeps malware isolated, separates work from daily tasks, and lets you undo mistakes.

The cornerstone of an RE lab is a virtual machine — a software computer running inside yours, with its own OS and files, sharing host hardware.

To run VMs you need a hypervisor: VirtualBox (free, beginner-friendly), VMware Workstation Player, or Hyper-V. We'll use VirtualBox.

Which guest OS? Kali Linux ships with RE tools preinstalled; Ubuntu suits a custom toolset; Windows is essential for Windows-specific targets.

Creating a VM follows the same arc everywhere: install the hypervisor, grab an OS ISO, make a new VM with RAM and CPU, add a virtual disk, then install the OS.

Network mode drives isolation: NAT shares the host IP for internet, Host-Only talks only to the host (most isolated), Bridged exposes the VM on your LAN.

A disassembler turns machine code into readable assembly. Ghidra is free and open-source with a decompiler; IDA Pro is the powerful commercial standard.

A debugger pauses a running program so you can inspect memory and step through execution. GDB rules Linux; WinDbg handles Windows and kernel debugging.

Round out your kit with utilities: a hex editor for raw bytes, file and strings to fingerprint binaries, and process monitors to watch live activity.

Your lab is ready! You set up VMs for safe isolation, picked a hypervisor and OS, and gathered disassemblers, debuggers, and utilities. Time for binary analysis.
