Posted: 03/20/2014 - In an 11 Call For Action alert, we're talking with local banks about fixing a potential security risk at ATMs. The problem is windows XP. It’s a computer operating system that’s more than a decade old, but 95% of bank ATMs still use it. Starting on April 8th, Microsoft will stop issuing security updates for XP. So if there are holes or flaws in the system, they won’t be fixed and it could be an easy target for hackers. We called several banks about what they're doing to fix their ATMs. US Bank: "U.S. Bank is fully aware of the upcoming change and will have converted all U.S. Bank ATMs to Windows 7 by the April deadline." Wells Fargo: Waiting for a response. First Bank: Waiting for a response. ENT Federal Credit Union: "We are aware of the Windows XP end-of-life date from Microsoft and have taken the appropriate measures to secure Ent’s systems. Ent’s staff and our vendor partners have been working since September to upgrade our Windows XP systems and are nearly complete. Any systems that have not been upgraded by Microsoft’s end-of-life date will be secured using other technologies." UMB: Waiting for a call back. Chase: Waiting for a manager to call us back. USAA: They're upgrading the software right now. A spokesperson says they didn't know when the transition would be finished. They will call us back Friday. TCF: Waiting for a call back. Key: We were told they acted early on to make sure ATMS are secure. Academy: Waiting for a call back.
