Summary

Malicious code in twilio-functions (npm)

Details

On npm install, the package's postinstall script executes index.js, which collects host identifiers (os.hostname(), os.userInfo().username, os.homedir(), process.cwd(), os.platform(), os.arch(), and selected environment variables) and POSTs them as JSON to a hardcoded webhook.site collection URL (https://webhook.site/42ce0f0e-a0a0-41b5-b157-1c0f918e064f). On network error, the code falls back to a DNS callback against an interactsh-style subdomain at 2b22ede784d5.oast.fun. Package metadata (name `twilio-functions` mimicking the Twilio SDK namespace, version 99.99.99, empty description) is consistent with a typosquat / dependency-confusion lure whose only on-install effect is the outbound reconnaissance beacon.
