Source Facts

Research published on 30 July found that several high-impact supply chain incidents tracked by GTIG involved code repositories, dependencies or developer tools. This conclusion relates to the research sample and does not mean all open-source packages are problematic.

Official guidance recommends maintaining inventories of software and build dependencies, controlling the introduction of new packages, and reducing long-lived privileged credentials. The article distinguishes compromised traditional software update channels from attacks on open-source dependencies.

Next Steps for Businesses / Editorial Observations

Organisations need to know which packages enter each build process and which credentials that process can access.

Next steps you can take

  • Inventory direct and indirect dependencies and build tools.
  • Establish a package update review process, narrow build-account permissions and arrange rollback.
