60. Essential Web Security Testing Tools

Knowing good tools is fundamental to web hacking. Whether for CTFs or real bug bounties, these tools are essential.

Proxy Tools​

Burp Suite​

The Swiss Army knife of web hacking. It can intercept and modify all web traffic.

Core features:

  • Proxy - Intercept HTTP/S traffic
  • Repeater - Resend requests
  • Intruder - Automated attacks (fuzzing)
  • Scanner - Automated vulnerability scanning (Pro)

Basic workflow:

  1. Configure the browser proxy (127.0.0.1:8080)
  2. Install Burp's CA certificate
  3. Start capturing traffic
  4. Browse the target site
  5. Send interesting requests to Repeater
  6. Manipulate parameters and resend

Free vs Pro: The free version is sufficient to get started. Its only limitations are the Scanner and Intruder speed.

OWASP ZAP​

An open-source alternative. Similar to Burp, but completely free.

Advantages:

  • Free automated scanner
  • Python scripting support
  • Active community

Disadvantages:

  • Somewhat clunky UI
  • Slower workflow than Burp

Scanning & Reconnaissance​

Nmap​

The legendary network scanner. It finds ports and services.

# Basic scan
nmap target.com

# Service-version detection
nmap -sV target.com

# Full port scan
nmap -p- target.com

# OS detection + scripts
nmap -A target.com

Nikto​

A web-server vulnerability scanner. It quickly finds common issues.

nikto -h https://target.com

Gobuster / ffuf​

Directory brute forcing. Finds hidden endpoints.

# Gobuster
gobuster dir -u https://target.com -w wordlist.txt

# ffuf (faster)
ffuf -u https://target.com/FUZZ -w wordlist.txt

Exploitation Tools​

SQLMap​

The ultimate SQL Injection automation tool.

# Basic test
sqlmap -u "https://target.com/page?id=1"

# Dump databases
sqlmap -u "URL" --dbs

# Extract tables from a specific database
sqlmap -u "URL" -D dbname --tables

Note: Real-world use may require WAF-bypass options.

XSStrike​

XSS vulnerability detection and exploitation.

xsstrike -u "https://target.com/search?q=test"

Commix​

An automated Command Injection tool.

Utilities​

CyberChef​

A browser-based data-transformation tool. It handles encoding, decoding, encryption, and more.

Example uses:

  • Base64 decoding
  • JWT parsing
  • Hash cracking
  • XOR brute force

jq​

The definitive JSON parser. Essential for analyzing API responses.

curl https://api.target.com/users | jq '.[] | select(.role=="admin")'

curl / httpie​

CLI HTTP clients. Useful for quick testing.

# curl
curl -X POST https://target.com/api -d '{"key":"value"}'

# httpie (prettier)
http POST target.com/api key=value

CTF-Specific Tools​

pwntools (Python)​

For binary exploitation. It is useful on the web too.

from pwn import *

# Remote connection
r = remote('target.com', 1337)
r.recvuntil('> ')
r.sendline('payload')

Requests (Python)​

The foundation of web automation.

import requests

s = requests.Session()
r = s.post('https://target.com/login',
           data={'user':'admin', 'pass':'test'})

Learning Path​

  1. Week 1: Master Burp Suite—practice every feature
  2. Week 2: Learn scanning tools—Nmap, Nikto, ffuf
  3. Week 3: Automate exploitation—SQLMap, XSStrike
  4. Week 4: Scripting—Python + requests + pwntools

Practical Tips​

Combining tools is the key:

  • Scan ports with Nmap → discover a web server
  • Explore directories with ffuf → discover a hidden API
  • Analyze requests with Burp → discover SQL injection
  • Automate with SQLMap → extract data

Manual > automated: Automated tools are only a starting point. Real skill comes from manual analysis.

Legal caution: Test only your own systems or targets for which you have explicit permission. Practice on CTF platforms such as HackTheBox and TryHackMe.

Tools are only a means; understanding is the goal.
