VERY IMPORTANT

The operators behind NetWalker (aka Mailto) ransomware have proven time and time again that they do not hold back. In a time where even some of the most active ransomware-centric actors are backing off from attacking medical targets due to the COVID-19 pandemic, NetWalker ransomware continues to attack them. In recent weeks, U.S. educational institutions have been heavily targeted with NetWalker ransomware. Michigan State University, University of California San Francisco and Columbia College of Chicago have all been hit.
