Practice Verified Codes and Commands:

1. HTML Injection (HTMLI) Exploitation:


<h1>Example of a simple HTML injection payload</h1>

<script>alert('XSS')</script>

2. Credentials Disclosure Exploitation:


<h1>Using curl to test for credentials disclosure</h1>

curl -X POST -d "username=admin&password=admin" http://example.com/login

3. Python Script for Automated Testing:

import requests

target_url = "http://example.com/login"
data = {"username": "admin", "password": "admin"}

response = requests.post(target_url, data=data)
if "Login failed" not in response.text:
print("Credentials might be valid!")
else:
print("Login failed.")

4. Bash Script for Red Teaming:

#!/bin/bash

<h1>Simple port scanner</h1>

for port in {1..65535}; do
(echo > /dev/tcp/192.168.1.1/$port) >/dev/null 2>&1 && echo "$port open"
done

5. SQL Injection Test:


<h1>Basic SQL injection payload</h1>

' OR '1'='1

What Undercode Say:

Penetration testing and bug bounty hunting require a deep understanding of various vulnerabilities and exploitation techniques. HTML Injection (HTMLI) and Credentials Disclosure are common issues that can be exploited using simple scripts and commands. For instance, HTMLI can be tested using basic payloads like <script>alert('XSS')</script>, while credentials disclosure can be checked using tools like `curl` to send POST requests with potential credentials.

In addition to manual testing, automation plays a crucial role in identifying vulnerabilities efficiently. Python scripts can be used to automate login attempts, while Bash scripts can help in scanning open ports on a target system. SQL injection, another critical vulnerability, can be tested using payloads like ' OR '1'='1.

For those interested in red teaming, learning to write and execute Bash scripts for network scanning and enumeration is essential. Tools like `nmap` and `Metasploit` are also invaluable for comprehensive penetration testing.

To further enhance your skills, consider exploring online courses and certifications such as eCPPT, CEH, and CRTP. These certifications provide in-depth knowledge and hands-on experience in ethical hacking and penetration testing.

Useful Commands:

  • Linux:
    nmap -sV -p 1-65535 192.168.1.1
    
  • Windows:
    [cmd]
    netstat -an | find “LISTENING”
    [/cmd]

Conclusion:

Mastering penetration testing and bug bounty hunting involves continuous learning and practice. By leveraging scripts and commands, you can efficiently identify and exploit vulnerabilities. Stay updated with the latest security trends and consider pursuing advanced certifications to enhance your expertise.
