Ensure your database user account does not have permission to execute sensitive packages like DBMS_PIPE unless absolutely necessary [8].
Use "allow-lists" to ensure only expected characters (like letters and numbers) are accepted [7].
The goal of this specific "Sleep" command isn't to steal data immediately, but to . If the application takes exactly 5 seconds longer than usual to respond when this string is entered, the attacker knows the database is vulnerable to SQL injection [2]. Once confirmed, they can use similar time-based techniques to extract sensitive data one character at a time. How to Protect Your System

Use "Prepared Statements" so the database treats the input as literal text, not executable code [7].
