Cyber Security Complete Course 2026 | From Zero to Job Ready Ethical Hacker + Blue Team Expert | The Techzeen - Cyber Security Tutorial #35: SQL Injection Live Demo ⚠️ Payloads, Exploits & Fixes (Kali 2025)

SQL Injection Practical Demo — Live Lab (2025) In this video of Cyber Security Tutorial, I perform a full hands‑on SQL Injection lab in a safe Kali Linux environment. Watch live payloads in action, see how simple inputs manipulate SQL queries, and learn exactly how developers must fix these flaws. Demo Steps (what I did): * Pulled & ran a vulnerable test app container on Kali (local lab). * Setup the test app in browser (create DB, set Security = Low for demo) * Navigated to the SQL Injection page and executed payloads live * Observed responses, errors, and data leakage — explained why each payload works * Discussed defenses and how to stop each attack. Live payloads shown (educational only): * ' OR '1'='1' # — classic login bypass * 1 ORDER BY 1 # — basic enumeration technique * 1' UNION SELECT NULL,NULL -- # — UNION-based data retrieval concept * Blind / existence checks: 1 AND 1=1 # , 1 AND EXISTS(SELECT 1 FROM users) # What you’ll learn: ✅ How to set up a safe local lab for SQLi practice ✅ How basic input manipulations alter SQL query logic ✅ Differences between in-band (UNION), enumeration/error, and blind techniques ✅ How to detect SQLi in testing (error messages, content changes, timing) ✅ Practical defenses every developer must apply: Prepared Statements / Parameterized Queries, input whitelisting, least‑privilege DB accounts, hide verbose DB errors, logging & monitoring, patching and WAF as defense‑in‑depth ⚠️ LEGAL & SAFETY (MUST READ): Educational Use Only: All demonstrations were performed in a controlled lab environment using a local vulnerable test app (container). Do NOT run SQLi payloads on systems you do not own or do not have explicit written permission to test. Misuse is illegal and unethical. If you find vulnerabilities on third‑party sites, follow responsible disclosure — do not download or share sensitive data. ⭐ Liked the video?
