All because of a simple, indexed URL containing pk id 1 . While SQLi is the primary concern, inurl:pk id 1 can also hint at other vulnerabilities. Path Traversal If the parameters are used to include files, an attacker might try: ?pk=../../../../etc/passwd Cross-Site Scripting (XSS) If the parameters are reflected back to the user without sanitization: ?pk=<script>alert('XSS')</script>&id=1 How to Defend Your Website Against These Attacks If you run a website and you suspect you have URLs containing ?pk= or ?id= , you are a potential target. Here is your security checklist. 1. Use Parameterized Queries (Prepared Statements) This is the single most effective defense. Never concatenate user input directly into a SQL string.
Within minutes, the attacker has dumped the entire database: customer emails, hashed passwords, credit card numbers, and internal admin credentials.
Published by: The Cyber Security Review Reading Time: 7 minutes Introduction: What is "inurl:pk id 1"? If you have spent any time exploring the darker corners of web security, penetration testing, or even casual browsing on tech forums, you may have come across a peculiar search string: inurl:pk id 1 . inurl pk id 1
inurl:pk id 1 is effectively searching for URLs that contain the parameters pk AND id AND also contain the numeric value 1 .
An attacker goes to Google and types inurl:pk id 1 . Google returns 1,200 results. Among them is: https://www.example-shop.com/view.php?pk=1&id=1 All because of a simple, indexed URL containing pk id 1
In a real-world example, this might find a URL like: http://vulnerablesite.com/index.php?**pk=1**&**id=1** What makes this specific dork so valuable to malicious actors? It represents a goldmine of potential SQL injection (SQLi) vulnerabilities . 1. Parameter Mapping to Database Queries When a developer writes an insecure SQL query, it often looks like this:
The server returns: "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version..." Bingo. The attacker now knows the site uses MySQL and is vulnerable to injection. Here is your security checklist
For developers, the lesson is clear: For system administrators, the lesson is: Assume your site is already in some hacker's Google dork list.
