WannaCry is a ransomware/worm attack at a scale that we haven't seen in almost a decade. This is the first attack of it's kind that combines ransomware with a worm as its delivery method. Read more about the attack here. I'll do a followup blog post about the specifics but the most important thing right now is to make sure that your computers are properly updated.
The patch that closes the vulnerability that this worm exploits was released in March. If your Windows Updates are current then you are fine. If you aren't sure, you can check by following these instructions for Windows 7/Windows 10. Please note that these aren't my videos but am sharing them for the sake of time.

Window 10: https://www.youtube.com/watch?v=1IA97wUjjRE
But seriously, if you're still using Windows XP/Server 2003 we REEEEEALLY need to talk... :)
If you have any trouble with any of these procedure, please contact us and we'll be happy to help!
