Scott and Wes break down the “Mini Shai-Hulud” supply chain attack that compromised TanStack and other popular npm packages through a clever GitHub Actions cache poisoning exploit; a self-propagating worm that stole credentials and persisted through Claude Code hooks and VS Code tasks. They also cover how developers can protect themselves using pnpm’s security defaults, dev containers, and other practical defenses.
