CTF | OverTheWire | Wargames | Natas | Level 17 | Time-Based Blind SQL Injection with Python

In this video, I take on Level 17 of the Natas wargame series, one of the most exciting and challenging levels yet. This level introduces a time-based blind SQL injection vulnerability, and I’ll show you how to fully automate the exploitation process using Python.

🔹 What You’ll Learn:
✅ Understanding Time-Based Blind SQL Injection – How this technique works when there’s no visible output, relying on time delays to infer data
✅ Crafting SQL Payloads – Building precise and effective SQL injection payloads for this type of attack
✅ Automating with Python – Using the requests module to send POST requests and the time module to measure delays

This video is perfect for anyone learning web application hacking, SQL injection techniques, and automation with Python. I explain the concepts and code step by step, so even if you’re new to time-based attacks, you’ll be able to follow along and understand everything.

💡 Pro Tip: Mastering time-based blind SQLi is crucial because it’s a powerful technique for extracting data when no error messages or outputs are visible.

I totally get your point, now, thx Shifu, let me help you explain, if a character is in the password of the user, such as a, which we use %a% to capture, then this snippet return is true, and sleep(10) is a signal to let us know character a is in the password.😆😆😆You are the best!!!! Shifu.

Let me be honest, hahaha, since this is hard, I want to show that I am right. You are the best, Shifu, thx.😁😁😁
