SQL injection has topped vulnerability lists for two decades, and yet most tutorials still boil it down to "use parameterized queries" and call it a day. The SQL Injection Handbook won't let you off that easy.
You'll start by breaking a real, working login form — then fix it, and prove to yourself, with actual running code, why the fix works. From there you'll build a complete mental model of the bug: how relational databases really work, where untrusted input hides beyond the obvious search box, and the three channels (in-band, blind, out-of-band) that separate a real finding from a lucky guess.
You'll learn how to:
- Recognize a candidate injection point without wasting hundreds of requests
- Confirm boolean, error-based, and time-based injection with actual statistical discipline — not vibes
- Binary-search your way through blind extraction in a fraction of the requests brute force needs
- Read a database's own metadata catalog to prove impact without touching sensitive data
- Write up a finding that gets triaged fast instead of bounced back for "insufficient info"
- Lock down parameterized queries across Python, JavaScript, PHP, Java, Ruby, and Go
- Spot the ORM escape hatches (.raw(), text(), find_by_sql) that quietly undo all of the above
- Build defense in depth with whitelist validation, least-privilege database accounts, and detection rules that catch what your WAF can't
