Good Code (Immune): $query = $pdo->prepare("SELECT * FROM users WHERE id = ?");
Once targets are identified, the tool begins automated testing. It injects various payloads—syntax strings designed to trigger database errors—into the identified parameters. If the server returns a specific SQL error message (like a MySQL syntax error), the tool flags the URL as vulnerable.
The tool constructs a UNION ALL SELECT statement to pull data from system tables. For a MySQL database, it will attempt: UNION ALL SELECT 1,2,3,4,5,6,7,8,9 FROM information_schema.tables sqli dumper gold
: The "Exploiter" phase attempts to confirm if the identified URLs are truly injectable by testing common SQL payloads. In-Depth Analysis
: Once a target is confirmed as "injectable," the "Analyzer" identifies the database type, version, and column structure. Schema Exploration Good Code (Immune): $query = $pdo->prepare("SELECT * FROM
Bad Code (Vulnerable): $query = "SELECT * FROM users WHERE id = " . $_GET['id'];
: This step involves mapping out the database tables and columns to find valuable data, such as user credentials or configuration settings. Data Dumping The tool constructs a UNION ALL SELECT statement
Inexperienced users who download a cracked version from YouTube. They lack the skills to manually inject but use the tool to deface websites (adding a "Hacked by..." page) for clout.
The process typically begins with a "dork." A dork is a specific search engine query used to locate potentially vulnerable websites. SQLi Dumper often includes features to utilize search engines to find targets based on specific parameters (e.g., inurl:item.php?id= ). The tool crawls these URLs to identify input vectors.
