What this malware does

Part of the Mini Shai-Hulud supply chain attack campaign in which a threat actor compromised the npm account atool and published 631 malicious versions across 314 npm packages in an automated 22-minute burst. Each malicious version injects a preinstall hook that executes a 498KB obfuscated Bun script, using the GitHub API as a covert exfiltration channel. Credentials are committed to attacker-controlled repositories following Dune-themed naming patterns (e.g., harkonnen-melange-742). Stolen data includes AWS keys, GitHub PATs, npm tokens, GCP service accounts, Azure credentials, Kubernetes service account tokens, SSH keys, Docker auth configs, database connection strings, Stripe keys, and Slack tokens. Malicious versions also establish persistence via CI/CD workflow injection (a GitHub Actions workflow named Run Copilot dumps all secrets via toJSON(secrets)), AI agent session hooks, and a system daemon named kitty-monitor.

This specific package (@antv/l7plot) was modified to include a malicious preinstall hook executing the obfuscated Bun payload.

The package @antv/l7plot was found to contain malicious code.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

This package was compromised as part of the ongoing "Mini Shai-Hulud is back" worm by the TeamPCP threat actor.

The package will steal credentials and then propogate it to every package it has access to. The package also attempts to remain persistent.

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 @antv/l7plot (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @antv/l7plot across your stack and pipelines.

  2. If you installed it — respond

    @antv/l7plot 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 @antv/l7plot 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 @antv/l7plot 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. @antv/l7plot on npm has been identified as a malicious package (versions 0.6.11, 0.7.11 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
