Inside ShaiHulud 2.0: The Supply-Chain Worm That Read Your Secrets

In this episode, I sit down with Charlie Eriksen, the researcher who uncovered the Shai Hulud 2.0 campaign, for a deep dive into one of the wildest supply-chain attacks we’ve seen. What began as a strange detection quickly unraveled into a worm that spread across npm, GitHub, and even a compromised Open VSX extension.“Patient Zero” was AsyncAPI, where the attackers exploited a subtle GitHub Actions flaw that let them run malicious code inside the org’s own CI pipelines without their pull request ever being merged. Unmerged PR → full RCE → stolen org-level credentials.From there, the worm propagated through packages, harvested secrets with TruffleHog, dumped them into tens of thousands of GitHub repos, and, most shockingly, contained a wiper mode that deleted a victim’s entire home directory if it couldn’t create new repos.It’s a fascinating and slightly terrifying look at how modern supply-chain attacks actually work under the hood. Give it a listen.
