IT Security Alert: Update on Latest Global Ransomware Threat

Author: Katie Rose


Many news agencies continue to report on the latest global ransomware threat that has affected corporations and institutions in the United States.

Ransomware is a type of security threat that holds your files hostage until you pay money. This serious threat is known as Petya, and it is very similar to the WannaCry threat that was publicized in May. Most computers at Notre Dame are already protected from both Petya and WannaCry.  

Petya ONLY affects Windows computers that have not received the most recent updates. Most University-owned Windows computers at Notre Dame already have that update. Petya does NOT affect Mac computers.  

If you are unsure if your Windows computer has received the update that protects against Petya, please work with your departmental IT support team, or call the OIT Help Desk.

You can take some important steps to protect yourself from threats like Petya and WannaCry such as:

  • Beware of clicking links in email, even when you know the sender
  • Make sure your computers and all mobile devices are running the latest version of the operating system and have the latest updates
  • Run antivirus and anti-malware software regularly, and update it frequently
  • Regularly backup your files to secure locations

If your computer becomes the victim of a ransomware threat, do NOT pay to get to your files.  Instead, call your departmental IT support team or the OIT Help Desk immediately.

If you have any questions, talk with your departmental IT support team, or contact the OIT Help Desk at 574-631-8111 or
