SQL Injection (SQLi) : If a website does not properly "sanitize" the parameter, an attacker could change to a malicious command to steal data or gain access. Database Structure
Modern web development favors "Pretty URLs" (e.g., /user/john-doe instead of ?id=1 ) because they are more secure and better for SEO. inurl pk id 1

SQL errors often reveal database structure. Search engines index these errors, making your inurl: pk id 1 page appear with juicy error text. On production servers, set display_errors = Off and log errors to a private file. Security researchers may use this dork with: SQL
For a defender, this dork is a free vulnerability scanner. Type it into Google. Look at your own organization’s domains. If you see results, you have just found a potential breach before the hackers do.
