OSV Malicious Advisory

OpenSSF/OSV advisory MAL-2026-12813 confirms this npm version as malicious. 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)...

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.

Decision reason

OpenSSF Malicious Packages via OSV confirms twilio-functions@99.99.100 as malicious (MAL-2026-12813): Malicious code in twilio-functions (npm)
