Malware on POS
I was reading an article about a retailer having a data breach due to malware running on their POS machine. I have what is probably a dumb question but I'll ask anyway. How does malware get installed on a POS machine? I have limited experience in the retail space, but I have done a few consulting gigs. From what I've seen, the POS systems were running an embedded version of Windows XP, which I know is no longer supported and could easily be a vulnerability. My confusion is how malware would get installed to begin with. I wouldnt think these POS machines would need internet access.
