From tj-actions to npm Worms: A Guide to Securing the Go Supply Chain
rseroter · x · 2026-08-05
This article explores how to build a secure software supply chain for Go projects in 2026. The author emphasizes that modern attacks rarely exploit bugs in the victim's code; instead, they infiltrate through compromised dependencies or build tools.
The post reviews two major supply chain incidents from 2025:
- tj-actions/changed-files compromise (CVE-2025-30066): Attackers shifted version tags in a popular GitHub Action, leaking CI secrets across roughly 23,000 repositories.
- Shai-Hulud worm: The first self-propagating worm in the npm ecosystem, which scanned for tokens upon package installation and auto-published trapped versions.
Using these examples, the article argues that true security lives in the pipeline and provides a step-by-step DevSecOps guide for Go developers to harden their supply chains.
