Lessons From WannaCry

Recently, you most likely watched widespread news coverage of a new cyber attack called WannaCry.  It infected over 200,000 computers worldwide and locked numerous organizations out of their data, including hospitals in the United Kingdom.  There are several reasons this attack gained so much attention.  First, it spread rapidly from computer to computer by attacking a known weakness in Windows computers.  Second, the attack was a type of malware called Ransomware, which meant that once it infected your computer it encrypted all your files, locking you out of your data.  The third and most important reason this attack gained so much attention was because it never should have happened.  The weakness that WannaCry attacked in Windows computers was well known by Microsoft, which had released a fix months earlier.  But many organizations failed to install the fix, or were still using operations systems that are no longer supported by Microsoft.  Here are three simple steps you can take to make sure attacks like WannaCry never infect your computers.
