WanaCry Ransomware Alert

On Friday, May 12, 2017, computers in nearly 150 countries were infected with ransomware, a type of computer infection that locks users out of the computer's files until a ransom is paid. While ransomware has been a threat for years, this particular strain, called WanaCry, caused a major disruption for several thousand businesses and individuals.

How does ransomware work?

  • Ransomware encrypts files on an infected computer and stops the computer's owner from accessing their files until a ransom is paid.
  • Ransomware is spread via an email that attempts to lure the reader into clicking links or opening attachments that contain the ransomware.

What do I need to do?

  1. Install the free security patch available from Microsoft (more details at https://technet.microsoft.com/en-us/library/security/ms17-010.aspx).
  2. Install Norton™ Security Suite if you don't have it, and make sure it is up-to-date if you do have it.

Tips to Protect Against Ransomware

  • Think before you click: Never click a link within an email or download an attachment if you are unsure about the email's authenticity.
  • Update Devices and Apps: Make sure your computer and mobile device is updated to the latest software version available. Additionally, all of your apps should be updated to the latest version. This helps keep your data secure.
  • Have good password hygiene: Your passwords should contain a mix of case-sensitive letters, numbers, and symbols, and it should be unique to each website. This way, if one account is compromised, your other accounts will still be safe.
  • Back up important files: Keep copies of important files by backing them up on a cloud service or external hard drive.
