7. Global Payments
In late March, transaction processor Global Payments confirmed a network penetration resulting in the data theft of approximately 1.5 million credit cards. The theft included Track 2 data, which can be used to clone credit cards. Although credit card numbers were believed to have been taken, other information, such as names, addresses and social security numbers were apparently not breached. While it was initially believed that the breach had only impacted merchant applicants, the company later confirmed that it affected consumers, as well.
