What is the Axios NPM supply chain attack ?

Hackers stole creds, pushed malware-laden versions of axios and kin via postinstall scripts. Executed on install, pulled after hours—but damage window existed.

How do I stop postinstall scripts in NPM?

npm install --ignore-scripts. Add ignore-scripts=true to .npmrc for default.

Does pinning dependencies prevent supply chain attacks?

Partially—for directs. But transitive deps (99% of risk) slip through without overrides. Better: loose ranges + audits + script blocks.
