Malicious code in @avi892nash/aegis-grid-runner (npm)

Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @avi892nash/aegis-grid-runner

What this malware does

The package's default bin action starts an HTTP server (grid.mjs) that listens on GRID_RUNNER_PORT (default 7719). Incoming requests carry a base64-JSON x-job-meta header containing a cmd string plus a gzipped code tarball; the runner decodes the header, extracts the tarball, and invokes child_process.spawn on meta.cmd in a shell on the host running the runner. The runner boots unpaired by default and accepts pairing via POST /api/master; token authentication (GRID_TOKEN) is optional per README, so a peer able to reach the port can pair and drive arbitrary shell command execution on the host. The bundle also contains references to internal Juspay infrastructure (ssh://[email protected]/picaf/aegis.git) and internal LAN addresses (192.168.0.50:7719, 192.168.0.146:7717) used as example onboarding strings, indicating an internal tool published to the public registry.

Detection & response playbook

Malicious package

  1. Find it

    Search your lockfiles and build artifacts for @avi892nash/aegis-grid-runner (version 0.3.3).

  2. If you installed it — respond

    Remove @avi892nash/aegis-grid-runner from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

  3. Did it already run?

    If @avi892nash/aegis-grid-runner 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
