WannaCry ransomware: Action required

Please update Windows computers by 5:00pm today (Tuesday, May 16). Restart your machine to have updates take effect.

Windows computers that are not up to date on Microsoft security update MS17-010 at that time will be temporarily disconnected from the UO network by the UO Information Security Office. 

Windows has a vulnerability

For specific information as to the worldwide impact of this vulnerability, check out The New York Times article on the WannaCry ransomware exploit.

The Microsoft Security blog has more information for Windows consumers here as well.

Action items for you

  • Deploy Microsoft Windows Updates immediately, and no later than 5:00pm today (Tuesday, May 16).
  • Restart your machine following the update process.

What we are doing

CASIT is working on a small list of specific, known, vulnerable hosts and contacting those customers where possible and having them update their machines. If we don’t contact you, run updates and restart your machine as this is the best way to ensure your machine/device is not vulnerable.

The Information Security Office continues notifying departmental IT staff of machines in their departments that are vulnerable to network propagation of this threat, and will notify them again today before 5:00pm. 

If you have any questions, please contact us by email: or by phone at x6-2388.
