The Global Ransomware Attack + What You Should do Now

May 2017 | Article

Initial Attack
On Friday, May 12, organizations all around the world were victims of ransomware attacks. Cybersecurity experts tracked more than 200,000 coordinated ransomware attacks in over 150 countries. Ransomware locks the files on an infected computer rendering them inaccessible.  The victim is then instructed to pay the hackers a “ransom” before the files can be unlocked. The British National Health System was one of these victims, causing hospitals across the United Kingdom to turn away patients. Other victims included Russia’s Interior Ministry and Telefonica (one of the largest private telecommunications companies in the world). The attackers demanded ransoms of only $300, indicating that their goal was to infect as many organizations as possible – irrespective of size. Even small and mid-sized organizations were targeted.

Attack #2
On Sunday, May 14th a new strain of ransomware was released by criminal hackers. Both versions can spread itself automatically across all workstations in a network, causing a global epidemic. If users or a co-worker are not paying attention and accidentally open one of these phishing email attachments, you might infect not only your own workstation, but immediately everyone else's computer too.  After the initial infection the ransomware will automatically spread itself to unpatched systems or systems with open shares. The patch to prevent the automatic spreading was released by Microsoft in March 2017, protecting those who had already updated their systems and did not have open shares. Open share are folders that are accessible to anyone on the network.

What Should I Do Now?

  1. Be on guard. Businesses of all sizes across every industry face ever-increasing risk of attacks to their computer systems and networks. Without appropriate preparation, monitoring, and response, their operations could be negatively impacted or their critical data lost. 
  2. Be very careful when you get an email with an attachment you aren’t expecting or did not ask for. If there is a .zip file in the attachment, do not click on it but delete the whole email. Remember: "When in doubt, throw it out!"
  3. Keep your systems secure with the latest patch and update releases for your computer operating system. You can confirm that your Microsoft system is up to date by going to or turn on automatic updates with Microsoft by following these steps. The latest patch from Microsoft on this vulnerability can be found here.
