This code snippet, -9108 UNION ALL SELECT 34,34# , is a classic example of syntax used for testing vulnerabilities in a database.
🚩 Seeing -9108 UNION ALL SELECT 34,34# in your input fields.
This is a textbook SQL Injection test. The attacker is trying to see if they can manipulate your database output. If you see "34" pop up where a username or product should be, you’ve got a vulnerability.

Ever seen a weird string like -9108 UNION ALL SELECT 34,34# in your server logs? It’s not a glitch—it’s a probe.
In a real-world scenario, attackers use this to "force" the database to return their own data alongside legitimate query results. The -9108 is often an intentionally invalid ID meant to clear the "real" results so that only the injected 34,34 appears in the output.
Attackers use the operator to append their own data to your query results. By using a non-existent ID like -9108 , they ensure the original data is hidden, leaving only their injected values (the 34,34 ) visible. The # at the end simply comments out the rest of your original code to prevent syntax errors.
