What this malware does

This package appears to be part of the tea.xyz token reward campaign that flooded npm. These packages typically contain autopublish scripts (auto.js, autopublish.js, autopublish2.js, autopublish3.js) designed to automatically generate and publish derivative packages with randomized names to inflate developer reputation scores for tea protocol token rewards. The malicious payload modifies package.json to remove private flags, changes version numbers, generates random Indonesian-themed package names (some variants are also in English), and continuously republishes variants to pollute the npm registry.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for antares-epimetheus-chromedriver-dependencies (all published versions).

  2. If you installed it — respond

    antares-epimetheus-chromedriver-dependencies 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 antares-epimetheus-chromedriver-dependencies 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.
