SQLi/Dork SQL Hacking: Theoretical Overview and Tips

[gutbigo]

SQL injection is one common technique used in SQL hacking. It involves inserting malicious SQL queries into input fields on a website, manipulating the underlying SQL statements and potentially gaining unauthorized access to data or performing unintended actions. This vulnerability occurs when user inputs are not properly sanitized or validated before being incorporated into SQL queries.
Tips for Prevention:

• Input Validation: Implement strict input validation techniques to ensure that only expected data types and formats are accepted, and sanitize all user inputs.
• Parameterized Queries: Use parameterized or prepared statements with bound parameters to separate SQL code from user-provided data.
• Principle of Least Privilege: Limit database privileges to minimize the potential impact of an SQL injection attack.
• Regular Updates: Keep your DBMS up to date with the latest security patches and fixes.
• Error Handling: Avoid displaying detailed error messages to users, as they can provide valuable information to potential attackers.
