Implement modern security headers to prevent unauthorized scripts from running on your site. Final Thought

Limits results to specific formats (PDF, PHP, LOG, etc.). Breaking Down "inurl:php?id=1"

The "1" is simply a common starting point. Hackers and security researchers use "1" because almost every database-driven site has a record with an ID of 1. Why is This Keyword Popular?

: Changing the URL to page.php?id=1' breaks the SQL syntax if the input is unsanitized. If the website displays a database error message (e.g., "You have an error in your SQL syntax" ), it confirms that the application is vulnerable.

To understand why this specific string is so significant, it helps to break down its components:

$id = $_GET['id1']; $query = "UPDATE products SET stock = stock - 1 WHERE product_id = $id"; mysqli_query($connection, $query);

Google dorking, or Google hacking, involves using advanced search operators to find information that is not easily accessible through standard search queries.

SecRule ARGS:id1 "!^\d+$" "id:100,deny,msg='SQLi - id1 must be numeric'"

In this example, an attacker is attempting to inject malicious SQL code by adding a single quote ( ' ) and the upd keyword to the id parameter.

To prevent your update scripts from appearing in Google dorks in the first place:

: Tells Google to look for the following string within the URL of a website.
