Working with Parrot Security Tools

Information Gathering

Before any security assessment, gathering information is crucial. Parrot includes powerful reconnaissance tools:

Network Scanning with Nmap

# Basic scan
nmap target_ip

# Comprehensive scan
nmap -sS -sV -sC -A -O -p- target_ip

# Scan with output to file
nmap -sS -sV -oA scan_results target_ip

Web Reconnaissance

# Scan website for vulnerabilities
nikto -h http://target_website.com

# Directory discovery
dirb http://target_website.com

# CMS scanning
wpscan --url http://wordpress_site.com

Vulnerability Assessment

Identify security weaknesses using Parrot's vulnerability scanners:

OpenVAS Setup and Usage

# Install OpenVAS if not already installed
sudo apt install openvas

# Set up OpenVAS
sudo openvas-setup

# Start OpenVAS services
sudo openvas-start

# Access web interface at https://localhost:9392
# Default credentials: admin/admin

Wireless Network Testing

Test WiFi security with Parrot's wireless tools:

Aircrack-ng Suite

# Put wireless interface in monitor mode
sudo airmon-ng start wlan0

# Scan for wireless networks
sudo airodump-ng wlan0mon

# Capture handshake (replace with actual BSSID, channel, and filename)
sudo airodump-ng -c [channel] --bssid [BSSID] -w [filename] wlan0mon

# Crack captured handshake
sudo aircrack-ng -w wordlist.txt [filename]-01.cap

Exploitation Frameworks

Parrot includes powerful exploitation tools for authorized penetration testing:

Metasploit Framework

# Start Metasploit
sudo msfconsole

# Basic usage example
use exploit/multi/handler
set payload windows/meterpreter/reverse_tcp
set LHOST your_ip
set LPORT 4444
exploit

Digital Forensics

Perform forensic analysis with specialized tools:

Creating Disk Images

# Create forensic image
sudo dd if=/dev/sdb of=disk_image.dd bs=4M status=progress

# Mount image for analysis (read-only)
sudo mkdir /mnt/evidence
sudo mount -o ro,loop disk_image.dd /mnt/evidence

File Recovery

# Recover deleted files
sudo foremost -i disk_image.dd -o recovered_files

Advanced Use Cases

Customizing Parrot Security OS

Make Parrot your own with these customization options:

Creating Custom Tool Collections

# Create a custom menu folder
mkdir -p ~/.local/share/applications/custom-tools

# Create a launcher for your custom script
nano ~/.local/share/applications/custom-tools/my-tool.desktop

# Add content like:
[Desktop Entry]
Type=Application
Name=My Custom Tool
Comment=Description of tool
Exec=/path/to/script.sh
Icon=/path/to/icon.png
Categories=Pentesting;CustomTools;

Building a Portable Pentesting Environment

Create a persistent USB installation:

1. Use a USB drive with at least 16GB capacity
2. Download the Parrot Security ISO
3. Use a tool like Rufus (Windows) or Startup Disk Creator (Linux) with persistence option
4. Allocate space for persistence (4GB+ recommended)
5. Boot from the USB and configure as needed

Professional Security Workflows

Building a Penetration Testing Methodology

Establish a structured approach using Parrot's tools:

1. Reconnaissance: Information gathering with Nmap, Maltego, etc.
2. Scanning: Vulnerability assessment with Nessus, OpenVAS
3. Exploitation: Targeted exploitation based on findings using Metasploit
4. Post-Exploitation: Privilege escalation, lateral movement
5. Documentation: Comprehensive reporting using built-in tools

Automating Security Tasks

Create scripts to automate routine security checks:

#!/bin/bash
# auto_recon.sh - Basic automated reconnaissance

target=$1
output_dir="recon_$(date +%F)_$target"

mkdir -p $output_dir

echo "[+] Starting reconnaissance on $target"

# Run nmap scan
echo "[+] Running Nmap scans..."
nmap -sS -sV -O $target -oA $output_dir/nmap_scan

# Web enumeration if port 80/443 is open
if grep -q "80/open\|443/open" $output_dir/nmap_scan.nmap; then
    echo "[+] Web ports found, running Nikto..."
    nikto -h $target -o $output_dir/nikto_scan.txt

    echo "[+] Running directory discovery..."
    dirb http://$target -o $output_dir/dirb_results.txt
fi

echo "[+] Reconnaissance complete. Results in $output_dir"
