SQL Injection (SQLi) is a form of injection attack designed to execute malicious SQL statements, exerting control over a database server associated with a web application. By exploiting SQL Injection vulnerabilities, attackers can circumvent security measures implemented in applications, bypassing authentication and authorization protocols to access the entire SQL database. This technique empowers them to not only retrieve database content but also manipulate records by adding, modifying, or deleting data.

We must recognize that SQL Injection vulnerabilities pose a threat to any website or web application utilizing an SQL database, such as MySQL, Oracle, SQL Server, and others. The repercussions of such vulnerabilities extend beyond mere breaches of security, as malevolent actors may exploit them to gain unauthorized entry to sensitive data, encompassing customer information, personal details, trade secrets, intellectual property, and more. As one of the oldest, most widespread, and perilous web application vulnerabilities, SQL Injection attacks have earned the top position in the OWASP Top 10 2017 document, compiled by the Open Web Application Security Project (OWASP), highlighting their critical impact on web application security.

Example of an SQL injection attack:

SQL injection attacks manifest in various ways, with hackers targeting individual websites, blogs, or more substantial entities like banks. In the case of financial institutions, unauthorized access enables attackers to manipulate account balances or tamper with transaction histories. Even after the breach is remedied, the subsequent customer notifications can inflict severe damage on the bank’s reputation.

Illustrating the real-world impact of SQL injection attacks, the gaming industry serves as a notable example. Video games, being a colossal and lucrative sector, frequently become the focal point of many SQL injection attacks. Although predominantly targeting US-based companies, hackers also direct their attention to countries such as Germany and the UK. Once infiltrated, attackers within the gaming realm can pilfer money, in-game currency, and purchased items, incurring actual financial losses for the targeted company and its user base.
