Microsoft has issued a warning about a very serious security vulnerability involving .rtf files. The virus associated with these .rtf files will create an open portal to your computer allowing a hacker to gain control of your computer.

Currently, Microsoft is working on a patch for this vulnerability but is advising users to avoid opening any files that have a .rtf extension, this includes previewing the file in Outlook, to prevent the installation of this virus.

What can you do?

  • Do not open, even in preview, any files with a .rtf extension.
  • Keep your Microsoft software up-to-date.
  • If you need to share a .rtf file, or if someone needs to share one with you, UM-Flint offers a web application called Filelocker for easy file sharing. More information can be found here:
