If you have a windows computer, make sure it is up to date. If you have XP/win 2003/ win 8 – Microsoft has special patches for you to protect against this recent worm. Good idea to patch up old systems because this worm was a doozy. https://blogs.technet.microsoft.com/msrc/2017/05/12/customer-guidance-for-wannacrypt-attacks/

Special thanks to https://twitter.com/MalwareTechBlog for stopping the spread. They registered the kill switch domain and the worm stopped propagating.

The vulnerability is still out there and waiting to byte so patch people!
