Episode notes
Wormlike Supply‑Chain Attack Explained
- The npm attacks were worm-like supply-chain updates that briefly published obfuscated malicious versions to millions of projects.
- The attackers aimed to steal crypto keys but only netted small amounts because the malicious releases were short-lived.
Phishing Drives Package Compromise
- Attackers gained maintainer access via phishing and abused npm publish permissions to distribute malicious updates.
- Even highly popular, well‑maintained packages can be compromised through social engineering.
Hosts Checked Their Own Projects
- Mike checked his projects and found they used debug and chalk but not the malicious versions, so they were safe.
- He inspected package-locks to confirm no nested updates pulled the compromised versions into their apps.
