Description

Adversaries may exploit a software vulnerability to take advantage of a programming error in a program, service, or within the operating system software or kernel itself to enable remote service abuse. A common goal for post-compromise exploitation of remote services is for lateral movement to enable access to a remote system.1

ICS asset owners and operators have been affected by ransomware (or disruptive malware masquerading as ransomware) migrating from enterprise IT to ICS environments: WannaCry, NotPetya, and BadRabbit. In each of these cases, self-propagating (“wormable”) malware initially infected IT networks, but through exploit (particularly the SMBv1-targeting MS17-010 vulnerability) spread to industrial networks, producing significant impacts.2


Procedure Examples

  • Bad Rabbit initially infected IT networks, but by means of an exploit (particularly the SMBv1-targeting MS17-010 vulnerability) spread to industrial networks.2
  • NotPetya initially infected IT networks, but by means of an exploit (particularly the SMBv1-targeting MS17-010 vulnerability) spread to industrial networks.2
  • WannaCry initially infected IT networks, but by means of an exploit (particularly the SMBv1-targeting MS17-010 vulnerability) spread to industrial networks.2
