In today's post we will focus on the issue of SQL Injection, one of the threats that can damage our website on WordPress and steal customer data. I invite you to the post.
SQL Injection is one of the most harmful and very common attacks on websites built on WordPress. In short, SQL Injections WordPress allows a hacker to access your database, which in turn damages your website, steals customer data, or fills it with malware.
In 2019, 2/3 of all attacks on WordPress sites used SQL Injection. The number of attacks decreased slightly in the following years, but this type of attack still poses a significant threat to all WordPress sites. Understanding and learning the principles of "SQL injection" will help protect against attack and data loss.
What is SQL Injection?
Let's start from the beginning. SQL Injection is a combination of two words from the English language. SQL is an abbreviation for "Structured Query Language" meaning the language used to create, modify, place or retrieve data from the database. Injection, on the other hand, means injection. If you are not advanced in WordPress, I will quickly explain the trinidad and tobago business email list database and how SQL Injection relates to WordPress. WordPress is an engine that connects to the database. Every WordPress site has a database, in which it stores information about e.g. users, WooCommerce orders, blog entries, links, comments, etc. It is actually a treasury with the most important information about the website on WordPress. If you want to check what database your website is connected to, you need to log in to your hosting via FTP and in the file located in the public_html folder we will find this information. Remember to never share this file with third parties. Having information for the database exposes you to many threats, which I will talk about in a moment. Let's get back to the topic. Now that we know what a database is in WordPress, what is SQL Injection?
What will we find in the database?
SQL Injection on WordPress is an attempt to gain unauthorized access to your website's database. This type of hacker attack uses the SQL language, which, as I mentioned, is responsible for interacting with the database. Clever use of this language allows you to extract the data of interest from the WordPress website - for example, the login and password of the site administrator. SQL Injection works when a hacker uses form fields to enter an SQL command into it and thus gains access to the database. Generally speaking, a hacker uses "unsanitized output data" . This is data entered by the user (in this case, the hacker), which is not checked or validated by the system (the website). The data is then executed by the database and sends the results back to the user. This involves very creative use of SQL commands to obtain the desired result.
