Malicious package

twilio-functionsnpm

twilio-functions is a confirmed malicious npm package (MAL-2026-12813) that steals credentials and exfiltrates sensitive data (malicious version 99.99.99). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in twilio-functions (npm)

MAL-2026-12813
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall twilio-functions

What this malware does

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.

Detection & response playbook

Credential / info stealer
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for twilio-functions (version 99.99.99). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging twilio-functions across your stack and pipelines.

  2. If you installed it — respond

    twilio-functions is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

  3. Did it already run?

    If twilio-functions was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks twilio-functions before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions

No. twilio-functions on npm has been identified as a malicious package (version 99.99.99 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
