According to several security researchers, a full screen lock that prevents access to various components of an ATM operating system could easily be bypassed. By pressing SHIFT key 5 times in a row, it allowed access to Windows settings and displaying the taskbar and Start menu of the operating system giving users to access deep within Windows XP from the touch screen. This vulnerability allow hackers to deploy malicious software or modify ATM boot scripts. All ATMs that are still running on Microsoft’s 16-year-old Windows XP operating system are at the risk of getting hacked easily, as the OS is no longer supported by the Redmond giant except for emergency security patches. And yes many ATM’s across the globe are still using Winodws XP.
