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.
At first glance, it looks like a typo or a fragment of a broken URL. However, in the world of ethical hacking and vulnerability research, this string is a well-known "Google Dork"—a search query that leverages Google’s advanced operators to find vulnerable web pages.
In this article, we will dissect exactly what inurl:pk id 1 means, how it is used maliciously, why it poses a severe risk to web applications, and most importantly, how developers and system administrators can protect their sites from the threats it uncovers.
Q: Is it illegal to search for inurl: pk id 1?
A: No. Searching public Google results is legal everywhere. However, attempting to exploit any site you find is illegal. inurl pk id 1
Q: Why does Google keep these dangerous links in its index? A: Google is a search engine, not a security auditor. It indexes the public web as it exists. It is the website owner's responsibility to protect their content, not Google's responsibility to guess intent.
Q: Can Google Dorks like this be used for good? A: Absolutely. Security researchers use them for bug bounty hunting. They find vulnerabilities, document them, and get paid by companies (like through HackerOne or Bugcrowd) to fix them.
Q: I found my company’s site using this dork. What do I do first? A: Don't panic. First, copy the exact URL. Second, contact your IT/security team. Do not try to modify the URL yourself. Third, ask them to check if that page is vulnerable to SQLi or IDOR. If it is, use the protection steps above. If you have spent any time exploring the
Q: Does this work on Bing or DuckDuckGo?
A: Google has the most powerful and reliable dorking operators. Bing supports some (like inurl), but DuckDuckGo intentionally strips most advanced operators for privacy reasons. For dorking, Google is the standard.
Attackers rely on predictable URL patterns. Instead of using ?pk=1&id=1, use strategies to hide your parameters:
Unauthorized access to systems discovered via Google dorks is illegal under laws like the Computer Fraud and Abuse Act (CFAA) in the US, Computer Misuse Act in the UK, and similar laws globally. If the parameters are used to include files,
If the parameters are used to include files, an attacker might try:
?pk=../../../../etc/passwd
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.
