One of the biggest data

breaches in history was the result of an SQL injection attack. In 2008,

Heartland Payment Systems, which was the sixth largest payment processor at the

time, discovered a major data breach that resulted in over 100 million cards being

compromised. This sophisticated attack was launched by a team of hackers who

identified SQL vulnerabilities and then made changes to the code so that they

could remain undetected and collect sensitive card information. This data was

then sold to other parties who could use it for their own criminal purposes.
