Bash Ransomware DarkRadiation Targets Red Hat- and Debian-based Distributions


We investigate how certain hacking tools are used to move laterally on victims’ networks to deploy ransomware. These tools contain reconnaissance/spreader , for Red Hat and CentOS, binary injectors, and more. In this blog, we focus on analyzing the worm and ransomware script.
