FOSS Code Supply Chain Assurance

Mitigate attacks through software dependencies

It is of the utmost importance to ensure that FOSS packages from public repositories have not been tampered with by malicious actors. This type of compromise is described as an open source "supply chain attack" and these have been increasing significantly. This project is building a new system (which is FOSS itself) to help verify the integrity of deployed code packages and validate their origin with external data sources, with the potential to mitigate attacks on open source packages supply chains such as: detecting if a package in use is matching verified code by matching source and binaries exactly and approximately. Or detecting abnormal code changes that may be signs of malicious modifications and possible attacks on a package.

The key components of this open code and data solution are a Package and File Fingerprints Database, a Code Similarity and Changes Detection Engine, utilities to detect possibly malicious changes in upstream projects, and integration in build system(s). While existing approaches may require a tight control of the whole code supply chain, the approach of this project is designed for practical usage with limited changes to a build and CI/CD pipeline.
