The attackers stole a whopping 130 million credit card numbers in one of the biggest data breaches of credit card data in history. In 2008, payment processor Heartland Payment Systems was hacked via SQL injection for over $130 million in losses. Even the best programmers are no match for an army of bots. Since the logic is so simple, SQLi attacks are easily automated. Tight deadlines can lead many companies to deprioritize security. Companies often hire developers with little experience or know-how, and proper security also takes longer to program. SQL injection vulnerabilities are often the result of shoddy programming by a web developer. How do SQL injection attacks work so easily? Well, they shouldn’t. In extreme cases, an SQL injection can turn over complete control of a database to an attacker.

Hackers can also install backdoors that give them access to a server indefinitely.Ĭommon SQL injection commands let hackers tamper with, steal, or destroy data spoof or steal identities or change database permissions. SQL injections can change, insert, and delete elements from a database or lay the groundwork for a denial of service attack. The database interprets this as a command to look through each user’s data, and to hand all of it over if the ID matches AVGRocks17 or if 1 equals 1 - which, of course, it always does. SELECT * FROM users WHERE userID = AVGRocks17 OR 1=1 Instead of filtering for a specific user, an SQL injection of, say, OR 1=1 into a search bar, login portal, or other entry field can force the SQL to query the database for all details of EVERY user. The asterisk above means “all details,” possibly including your real name and password. SELECT * FROM users WHERE userID = AVGRocks17

That is, SQL turns your entry into something like: “Go find user AVGRocks17 and give me their data.” You only have to type in “AVGRocks17,” but SQL translates the request into code that tells the database what to do. SQL makes your entry intelligible to the database. You’re trying to access your user data on a website, so you enter your username: AVGRocks17. Here’s an example of how an SQL injection attack is performed: Repeated SQL injections give hackers a good idea of a software’s degree of vulnerability. Websites with unsecured entry fields can be vulnerable to SQLi attacks. By altering the entry data with a malicious snippet of code known as an exploit, a cybercriminal can trick an unsecured database into interpreting the data as a command. Hackers perform an SQL injection attack through an entry field - such as a login portal, a form field, or a search bar - in a web API. How is an SQL injection attack performed? In case you’re wondering, you can pronounce SQL as “sequel” or “S-Q-L.” Check out our crash course on other cybersecurity terms if you’re a little fuzzy. Unfortunately, SQL’s capacity to interpret user input also makes it an easy target for hacking. SQL sits right behind the storefront, taking your requests and translating them into code for the database. It’s what you’re actually interacting with when you navigate a website and submit requests through an entry or form field (such as searching for an item). If a database is a web application’s warehouse, an API is like the snazzy storefront. SQL’s intuitive English-based syntax has made it the database management language of choice for many API programmers. When you enter information into a web application, SQL lets the database process the request and return the requested information.

A database is full of tables, which are like boxes holding data such as customer information, items for sale, or login credentials. Think of a database like a web application’s warehouse. When communicating with or querying a database to request information, SQL is the language most commonly used to access that data. SQL stands for s tructured query language and is the standard programming language used for database management. Potentially lucrative and relatively easy to pull off with the right skills and experience, SQL hacks are a main source of income for many hacker groups. Web application developers sometimes struggle to see their mistakes until someone else discovers them - which is why new products are often easy prey for SQL injection zero-day attacks.Īnd when they aren’t helping themselves to your data, skilled cybercriminals often sell your data to data brokers. SQL injection vulnerability is often the result of a poorly written API (application programming interface). OWASP, a non-profit leader in web security awareness, puts injections at the top of its list of web application security risks. Though SQL injection (SQLi) has been around for decades, it’s a persistent threat and represents two-thirds of web application attacks today.
