Payment data may leak due to hackers penetrating IT systems of businesses

Payment data may leak due to  hackers penetrating IT systems of businesses

Data leaks (or data breaches) occur when hackers penetrate the IT systems of companies that process payments. Once the hackers get into these IT systems, they can intercept information such as credit card numbers.

In 2014, a massive data leak of private and business clients occurred at JP Morgan Chase; clients’ details were accessed, but their credit card information was not. Earlier in 2013, Target was hacked; in that case, credit card information was leaked. The table below lists some of the largest data breaches in recent years.
