Practical Steps to Set Up OS for Bug Bounty Hunting

Setting up an OS for bug bounty hunting involves preparation, installation, and configuration to ensure a robust environment for finding vulnerabilities.

1. Preparation

• Check Hardware: Ensure laptop meets requirements (4GB RAM, 20GB storage, 64-bit CPU) using CPU-Z or `lscpu`.
• Download ISO: Get ISOs from official sites (e.g., kali.org, parrotsec.org, ubuntu.com).
• Verify ISO: Use SHA256 checksum (`sha256sum` or PowerShell) to confirm file integrity.
• Backup Data: Save files to external drives or cloud services to prevent loss during partitioning.

Preparation ensures compatibility. For example, verifying the Kali Linux ISO prevents corrupted downloads, while backups protect against data loss during setup.

2. Create a Bootable USB

• Insert USB: Use an 8GB+ USB drive (USB 3.0 recommended).
• Use Rufus/Etcher: Select ISO, write to USB in DD mode using Rufus (Windows) or Etcher (Linux/macOS).
• Verify USB: Check for boot files (e.g., EFI folder) using `ls` or File Explorer.
• Eject Safely: Ensure USB is boot-ready.

A bootable USB enables Live mode testing, ideal for bug hunters testing platforms like Bugcrowd without permanent installation.

3. Configure BIOS/UEFI

• Access BIOS: Restart and press F2, DEL, or F12 to enter BIOS/UEFI.
• Disable Secure Boot: Allow USB booting, as some OS (e.g., BlackArch) may not support signed bootloaders.
• Set Boot Order: Prioritize USB drive in the boot menu.
• Save and Exit: Reboot to load the OS boot menu.

BIOS configuration ensures booting. For Parrot OS, use `lsusb` to verify USB recognition and avoid boot issues.

4. Choose Installation Method

• Live USB: Boot without installation for temporary testing (e.g., Kali Live mode).
• Dual-Boot: Shrink Windows partition to install alongside another OS.
• Virtual Machine: Run in VirtualBox/VMware for isolated environments.
• Full Installation: Use guided partitioning for dedicated setups.

VM or Live USB setups are popular for bug hunters, allowing safe testing without affecting the primary OS.

5. Post-Installation Setup

• Update System: Run `sudo apt update && sudo apt upgrade` (Debian-based) or `pacman -Syu` (Arch-based).
• Install Tools: Add bug bounty tools (e.g., `sudo apt install burp-suite` for Kali).
• Configure Security: Set non-root user (`adduser`), enable firewall (`sudo ufw enable`).
• Optimize: Disable unused services (`sudo systemctl disable ssh`) to save resources.

Post-setup optimizes the OS for bug hunting. For WSL2, install Ubuntu via `wsl --install` and add tools like Nmap for seamless integration.
