Ever since the WannaCry and Petya ransomware outbreaks, healthcare organizations have been on their toes. But just when they thought they could relax, a new strain of ransomware has come along. A “Locky-variant” ransomware campaign is currently underway, and it’s every bit as dangerous as previous ransomware attacks.

In 2016, the Locky ransomware infected millions of users with a Microsoft Word file. It was eventually contained, and cyber security firms have since created protections to detect and block previous Locky variants. However, a similar malware is currently spreading worldwide and has so far infected tens of thousands of computers.
