ATMs could be left wide open to hackers next month when Microsoft ends tech support for the Windows XP operating system as the Windows XP deadline approaches.
ATMs running XP Embedded are not affected because Microsoft is not cutting off its support until 2016.
The process of upgrading to an alternative such as Windows 7 is both complicated and expensive for ATM operators – with many older machines needing to be altered one by one. Most are not expected to have made the switch within the next month.

In a notice on its site, the PCI SSC is urging firms to take the plunge: “Don’t make yourself an easy target, talk to your technology provider today and make sure your PC and systems are not putting your customers’ confidential payment card data and your business at risk.”
