SQL injection
SQL injection is a technique hackers use to trick your website into giving away private information.
A website uses a database to store information like user names and passwords. SQL injection happens when a hacker adds special code to a form or link on your site. This code makes the website run unwanted commands on the database. The hacker can then see things they shouldn't, like customer data or login details.
What it means
SQL injection works because websites often use a language called SQL to talk to their databases. If a hacker can get your website to run their own SQL commands, they can access, change, or delete data. This is especially bad if the database has sensitive information.
Why it matters
SQL injection can lead to data breaches, identity theft, and loss of customer trust. Hackers can steal credit card numbers, personal details, or even take over your website. It’s a common attack that can be very damaging if not stopped.
What to do
Use a web application firewall to block suspicious requests. Keep your website software and plugins up to date. Avoid building your own database queries; use secure frameworks that protect against this type of attack. Regularly scan your website for vulnerabilities to stay safe.
