Do you remember the huge credit card hack that forced Target's CEO to step down earlier this year? Now we know the same malware was used to infect Home Depot's point-of-sale software in the attack reported last week.
I'll explain how it works and show what to do to protect yourself.
The malware that cyber criminals are using is called BlackPOS. It piggybacks itself onto a physical store's credit card authorization system, and copies the personal information from every card swiped at an infected register. From there, the hackers sell packaged "dumps" of the stolen cards and personal information online.
What tipped security experts off about the Home Depot hack's similarity to Target was the place where the "dumps" were being posted. It was the same as the Target hack.
