Protection after May 12 “WannaCry” virus spreads

AOA encourages members to protect themselves against global cyberattacks

A global cyberattack last week—the ransomware nicknamed "WannaCry," which affected computers in 150 countries—is still sending shivers around the world and potentially lurking in more unprotected computers.

Be wary of suspect emails. Reach out to the sender to verify he or she was the actual sender before clicking on links and attachments.

Among those most impacted by the attack were Britain's public health system, FedEx, French automaker Renault, and universities in China. The shocking spread of the malicious software appears to have slowed, thanks to a British computer tech who disabled the computer code and kept it from doing more damage. The attack served as a reminder of our digital-age vulnerabilities.

Like other companies and groups, the AOA is verifying that all recommended security patches have been installed in its computer network.The AOA sends out regular updates as part of its security plan and policies at its corporate headquarters in St. Louis, Missouri, and its field office in Washington, D.C.The AOA also is working with groups, such as the AOA Board of Trustees, to reinforce best practices when it comes to the security of their computers.

What can AOA members do to protect themselves?

  • Make sure your Microsoft Windows updates are current and the fix, in response to the WannaCry virus, was applied. Always reboot when prompted after installing Windows Updates. (For reference, patch numbers are: KB4012212 or KB4012215).
  • Make sure your virus protection program is working and up to date. If not, install the latest updates and virus signature files. Pay attention to software warning messages located in the lower task bar on computer monitors.
  • Back up your files and data regularly.
  • Be wary of suspect emails. Reach out to the sender to verify he or she was the actual sender before clicking on suspicious links and attachments.


Authorities were investigating how hackers spread the malicious software, though typically ransomware is spread through email, links, uploaded documents or pop-ups. The hackers demand payment or ransom ($300 in the case of WannaCry) to unlock users' computers and regain access to their files.
