Am I at risk for WannaCry?

  • If you or your organization is running a version of Windows, you could be at risk.

What should I do to protect myself from WannaCry?

Individuals and small businesses should:

  • Run Windows Update to get the latest software updates.
  • Make sure any anti-virus product is up to date and scan your computer for any malicious programs. It's also worth setting up regular auto-scans.
  • Back up important data on your computer in case it gets held for ransom.

Large organizations should:

  • Apply the latest Microsoft security patches for this particular flaw.
  • Back up key data.
  • Ensure all outgoing and incoming emails are scanned for malicious attachments.
  • Ensure anti-virus programs are up to date and conducting regular scans.
  • Educate employees on identifying scams, malicious links and emails that may contain viruses.
  • Make sure to run “penetration tests” against your network's security, no less than once a year, according to the Department of Homeland Security.

What if I've already been attacked?

  • Do not pay the ransom demanded by the WannaCry ransomware, cybersecurity firm Check Point warned in a blog post Sunday. The company said there is no evidence of the hackers giving people files back.
  • Contact local IT support services.
  • Businesses should contact law enforcement and provide as much information as possible.
  • Restore backups of data.

How can I prevent ransomware attacks?

There are also steps that can be taken to protect against ransomware more generally. These include:

  • Restrict logging in to your computer using an account with Administrative rights; if your user account is in the administrators group, remove it.
  • Making sure anti-virus programs are up to date and updating all software.
  • Back up copies of data.
  • Scrutinize links and files contained in emails.
  • Only download software from trusted sources.
