On May 12, 2017, WannaCry ransomware infected 200,000 computers across 200 countries. 80 UK National Health Service organizations went down; Spain's Telefónica, Germany's rail system, FedEx—all hit. Estimated total damages exceeded $4 billion. Shocking fact: the patch for this vulnerability (MS17-010, EternalBlue) was already deployed by Microsoft Patch Tuesday on March 14—two months before infection. Had patches been applied timely, all this damage was preventable.
