What this malware does

The package dialogflow-es was found to contain malicious code.

This package was compromised by the Sha1-Hulud: The Second Coming NPM worm. The malicious payload steals tokens and credentials and publishes them to GitHub. The worm will propogate itself to NPM packages the user owns and establish persistence is a GitHub action. The package may also destroy the user's home directory.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for dialogflow-es (4 malicious versions).

  2. If you installed it — respond

    dialogflow-es 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 dialogflow-es was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Frequently asked questions

No. dialogflow-es on npm has been identified as a malicious package (versions 1.1.1, 1.1.2, 1.1.3, 1.1.4 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks dialogflow-es-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
