Just as IT and online security experts feared, another wave of the malicious WannaCry ransomware has appeared within the past few hours.  According to Wordfence Security spokesman Mark Maunder, “this is going to be a rough weekend for Windows users.”  So far, more than 100,000 PCs have been infected in more than 100 countries, making WannaCry one of the largest data crashes in web history.  Although anti-malware technicians have found two “kill switches” in the WannaCry program, this may not be enough to stop further PC infections and possible damage to national health, transportation, and communications infrastructure.

Despite the damage already done to older Windows Operating Systems, such as XP, there are a few ways to mitigate some of the ongoing damage.  Wordfence Security’s Mark Maunder has a few suggestions:

“WannaCry Ransomware: How to protect yourself”

  1. “If you use Windows, install the patch that Microsoft has released to block the specific exploit that the WannaCry ransomware is using. You can find instructions on this page in the Microsoft Knowledge Base. You can also directly download the patches for your OS from the Microsoft Update Catalog.
  2. If you are using an unsupported version of Windows like Windows XP, Windows 2008 or Server 2003, you can get the patches for your unsupported OS from the Update Catalog. We do recommend that you update to a supported version of Windows as soon as possible.
  3. Update your Antivirus software definitions. Most AV vendors have now added detection capability to block WannaCry.
  4. If you don’t have anti-virus software enabled on your Windows machine, we recommend you enable Windows Defender which is free.
  5. Backup regularly and make sure you have offline backups. That way, if you are infected with ransomware, it can’t encrypt your backups.
  6. For further reading, Microsoft has released customer guidance for the WannaCry attacks and Troy Hunt has done an excellent detailed writeup on the WannaCry ransomware.”  Please share this post with friends and family and urge them to upgrade their Windows OS as soon as possible.
