However, most search engines (including Google) automatically decode URL-encoded characters in search queries. Typing inurl:index.php%3Fid= is functionally equivalent to inurl:index.php?id= . The encoded form is sometimes used to bypass simple filters or to precisely target URLs that contain the literal %3F (though this is rare). For practical purposes, you can treat both as identical.
: If you have sensitive directories that shouldn't be indexed, use a robots.txt file to instruct search engines to stay away. Conclusion
Use parameterized queries so the database treats input as data, not executable code.
$stmt = $pdo->prepare('SELECT * FROM users WHERE id = :id'); $stmt->execute(['id' => $_GET['id']]); $user = $stmt->fetch(); Use code with caution. 2. Strictly Validate and Sanitize Input
The query inurl:index.php?id= is a primary reconnaissance tool for a specific, highly dangerous class of attack: . Attackers use this dork to automatically generate a list of potential targets.
Google sometimes rate-limits or blocks automated dorking. Alternatives include Bing (supports inurl: ), DuckDuckGo, or specialized search engines like Shodan (for internet-connected devices).
