CAPEC-692: Spoof Version Control System Commit Metadata

Version Control Systems are widely used by developers to host, track, and manage source code files in an easy and synchronous manner. These systems are often leveraged to host open-source software that other developers can incorporate into their own applications or use as standalone applications. To prevent downloading vulnerable and/or malicious code, developers will often check the metadata of VCS repository commits to determine the repository's overall pedigree. This may include a variety of information, such as the following: Owner of the repository Author(s) of commits Frequency of commits Date/Time of commits Repository activity graphs These precursory checks can assist developers in determining whether a trusted individual/organization is providing the source code, how often the code is updated, and the relative popularity of the software. However, an adversary can spoof this metadata to make a repository containing malicious code appear as originating from a trusted source, being frequently maintained, and being commonly used by other developers. Without performing additional security activities, unassuming developers may be duped by this spoofed metadata and include the malicious code within their systems/applications. The adversary is then ultimately able to achieve numerous negative technical impacts, while the victim remains unaware of any malicious activity.
