As I predicted in my recent articles about “The End of Windows XP” (part 1, part 2, part 3), the Internet Explorer browser that is part of Windows XP would be the most vulnerable part of the operating system now that Microsoft has officially ended support. I strongly advised that people should stop using Internet Explorer and switch to another web browser such as Google Chrome. Hopefully you have heeded my advice because a new vulnerability has been made public that effects every version of Internet Explorer ever made, including the now unsupported version of Internet Explorer 8 that runs on Windows XP.
Microsoft Security Advisory 2963983 details the vulnerability called CVE-2014-1776. It basically allows attackers to run code on your computer, which can potentially give them access to do malicious things to or with your computer.
If you are using Windows XP, please take action to install and use a different web browser immediately. Unless Microsoft goes against their own policy, Internet Explorer in Windows XP will NOT receive a security update and you will remain vulnerable indefinitely if you continue to use Windows XP. If you need help with this, please contact me and I will be happy to help.
