🎯 Day 16 – SQL Injection Bypass Techniques (Practical) | Bypass WAF, Filters & Input Validation

🚀 30 Days FREE Bug Bounty Series – Learn Ethical Hacking from ZERO (2025 Edition, Hinglish) 👨‍💻 Welcome to Day 16 of our Bug Bounty Series! Aaj hum SQL Injection ki bypass techniques cover karenge — matlab jab simple payload block ho jaye (WAF, input filters, encoding), to kaise advanced tricks se bypass kar ke vulnerability confirm karein. Ye sab advanced but practical hacks hain jo responsibly sirf authorized scopes pe use karne chahiye. 📚 Aaj ke video mein kya kya milega (Day 16): ✅ Common filters & WAF behavior samajhna ✅ Encoding / double encoding tricks ✅ Comment-based bypass (--, /* */) ✅ Case / whitespace / tab tricks ✅ Stack queries & stacked statements (where allowed) ✅ Boolean, Time-based & Error-based bypass tips ✅ Using sqlmap tamper scripts & custom tamper ideas ✅ WAF evasion with obfuscation (char(), concat(), hex) ✅ Practical demo ideas + log & PoC for report 🧠 Core Concepts (Short): Why bypass? Simple payloads often blocked by WAFs/input sanitizers. Bypass techniques help verify true vulnerability. Be careful: Aggressive bypassing can trigger alarms — keep ethics & scope in mind. 🛠️ Bypass Techniques & Example Payloads: Comment / Inline-Comment Bypass Encoding / Double Encoding URL-encode characters (%27 for ') or double-encode if first layer decodes once Whitespace Variations (Tab / Newline / CR) Replace spaces with /**/, \t,
, or 0x0a to bypass simple regex filters. Case / Unicode / Homoglyphs Use OR as oR, or Unicode homoglyphs to evade naïve filters. Char() / Concat / Hex Encoding Build strings using char(97)+char(100) or hex to bypass keyword detection. UNION SELECT 1,CHAR(65)+CHAR(66)-- UNION SELECT 1,0x616263-- Stacked Queries (if DB allows) Execute multiple statements: 1; DROP TABLE users; -- (Use only in controlled/lab environments — very dangerous) Using sqlmap Tamper Scripts --tamper=space2comment,between,randomcase etc. python3 sqlmap.py -u "http://target.com/item?id=1" --tamper=space2comment --batch Bypass WAF with Time-Based Techniques Use time delays (SLEEP(), pg_sleep()) wrapped or obfuscated: Error-based obfuscation Cause DB to return errors containing data using functions or heavy conversions. Logical/Arithmetic Transformations 🔧 Tools & Helpful Commands: sqlmap with --tamper and --random-agent options. Burp Suite + Repeater to test custom obfuscation. WAFW00F to fingerprint WAF and tailor bypass. Custom Python/regex scripts for payload generation. 🔎 Pro Tips (Practical & Ethical): Start with low-noise techniques (boolean) before time-based scans. Use minimal --level & --risk in sqlmap while testing on live scopes. Keep logs of commands, timestamps & outputs for the report. If WAF detected, fingerprint first (WAFW00F) and then decide tamper scripts. Never run destructive payloads on production targets. Always follow scope & responsible disclosure. ⚠️ Important — English Legal Disclaimer (MUST READ): This tutorial is provided only for educational purposes. The techniques demonstrated (including bypass and evasion methods) are powerful and can be misused. Use them only on: systems you own, authorized bug bounty targets, or controlled lab / CTF environments.
