This is what happened to computers infected with the Zeus/Zbot. The creator of the botnet built into the malware a Kill switch that causes the infected computer to “BSOD”
The botnet owner executed that Kill command recently essentially killing over a 100k machines by a single click of a mouse.
The sad thing the owners of those machines are probably still clue less. The kill command built into the malware does some major damage. Data may not be lost but OS will likely need to be reinstalled.
So have you seen a BSOD recently?
