What is the Axios supply chain attack?

Hackers stole creds, pushed malware via postinstall scripts in Axios and others during an npm breach. Executed on install, it stole data before detection.

How do I prevent npm postinstall script attacks?

Use `npm install --ignore-scripts`, commit lockfiles, run `npm audit`, and monitor with tools like Snyk.
