Real-World SQL Injection Impacts

The impact of SQL injection extends far beyond technical consequences. The 2008 Heartland Payment Systems breach, which exposed 134 million credit cards, began with SQL injection. The 2012 LinkedIn breach that exposed 117 million password hashes also started with SQL injection. These incidents resulted in millions of dollars in fines, lawsuits, and remediation costs, not to mention the immeasurable damage to reputation and customer trust.

SQL injection doesn't just affect large corporations. Small businesses and personal websites frequently fall victim because they lack the resources for comprehensive security testing. Attackers use automated tools to scan millions of websites for SQL injection vulnerabilities, exploiting whatever they find. Whether it's customer data, financial records, or intellectual property, any database accessible through a vulnerable web application becomes a potential target.
