Trust Wallet Hack Explained: The Shai-Hulud Supply Chain Attack

You didn't click a phishing link. You didn't download a sketchy file. You just ran npm install... and now your entire infrastructure is owned.

In this episode, we break down Shai-Hulud, the most sophisticated supply chain attack in history. This wasn't just a static piece of malware; it was a self-propagating worm that infected over 700 NPM packages, compromised 26,000 GitHub repositories, and led directly to the $8.5 Million Trust Wallet Heist.

We deconstruct the kill chain step-by-step: from the malicious preinstall scripts that run before you even see the code, to the GitHub Actions backdoors that turned CI/CD pipelines into botnets.

By the end of this video, you will understand:

The Infection: How a single command infected thousands of developer machines.
The Worm: How Shai-Hulud used stolen credentials to auto-publish malicious versions of other packages.
The Heist: The exact path attackers took from a developer's laptop to draining 2,500 Trust Wallets.
The Fix: Why the industry is banning "Classic" automation tokens in favor of OIDC Trusted Publishing.
