Neowin pulls attention to the fact that a whopping 95 percent of all active ATMs in the world still run Microsoft's Windows XP operating system.
Despite being one of the most frequently used consumer technologies in the world, many ATMs run on outdated operating systems. and with the April 8th deadline looming, their owners must make the upgrade. But this may be easier said than done for many of the machines, which run on outdated hardware that may struggle to keep up with a newer OS, like Windows 7. According to Suzanne Cluckey, the editor of ATM Marketplace, "A lot of ATMs will have to either have their components upgraded or be discarded altogether and sold into the aftermarket—or just junked." The machines that aren't promptly upgraded could face significant security vulnerabilities as more and more weak points in the OS are uncovered.
