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 initial access into and lateral movement throughout the ICS environment to enable access to targeted systems. (Citation: Enterprise ATT&CK) 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.

Vulnerability scanning is used to find potentially exploitable software vulnerabilities to remediate them.
M0942Disable or Remove Feature or ProgramRemove or deny access to unnecessary and potentially vulnerable software to prevent abuse by adversaries.
M0950Exploit ProtectionUse capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring.
