Supply Chain Compromise: Compromise Software Supply Chain

Adversaries may manipulate application software prior to receipt by a final consumer for the purpose of data or system compromise. Supply chain compromise of software can take place in a number of ways, including manipulation of the application source code, manipulation of the update/distribution mechanism for that software, or replacing compiled releases with a modified version.

Targeting may be specific to a desired victim set or may be distributed to a broad set of consumers but only move on to additional tactics on specific victims.[1][2]

ID Mitigation Description
M1051 Update Software

A patch management process should be implemented to check unused applications, unmaintained and/or previously vulnerable software, unnecessary features, components, files, and documentation.

M1016 Vulnerability Scanning

Continuous monitoring of vulnerability sources and the use of automatic and manual code review tools should also be implemented as well.[23]


ID Data Source Data Component Detects
DS0022 File File Metadata

Use verification of distributed binaries through hash checking or other integrity checking mechanisms. Scan downloads for malicious signatures and attempt to test software and updates prior to deployment while taking note of potential suspicious activity.
