VERY IMPORTANT

Proofpoint threat researchers recently analyzed Defray Ransomware, a previously undocumented ransomware strain. So far in August, we have observed only two small and selectively targeted attacks distributing this ransomware. One was primarily aimed at Healthcare and Education verticals; another targeted Manufacturing and Technology verticals. We selected the name “Defray” based on the command and control (C&C) server hostname from the first observed attack.
