KillDisk (b5532e91-d267-4819-a05d-8c5358995add)
KillDisk is a disk-wiping tool designed to overwrite files with random data to render the OS unbootable. It was first observed as a component of BlackEnergy malware during cyber attacks against Ukraine in 2015. KillDisk has since evolved into stand-alone malware used by a variety of threat actors against additional targets in Europe and Latin America; in 2016 a ransomware component was also incorporated into some KillDisk variants.[KillDisk Ransomware][ESEST Black Energy Jan 2016][Trend Micro KillDisk 1][Trend Micro KillDisk 2]
