Malicious package

@emilgroup/task-sdk-nodenpm

Malicious code in @emilgroup/task-sdk-node (npm) Remove it immediately and rotate any exposed credentials.

MAL-2026-2079
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @emilgroup/task-sdk-node

What this malware does

The package @emilgroup/task-sdk-node 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 by the CanisterWorm campaign by the TeamPCP threat actor. The malicious payload establishes persistence as user systemd service and places a backdoor on the infected host. The malware will also harvest npm credentials and can autonomously spread.

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 @emilgroup/task-sdk-node (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @emilgroup/task-sdk-node across your stack and pipelines.

  2. If you installed it — respond

    @emilgroup/task-sdk-node 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 @emilgroup/task-sdk-node 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 @emilgroup/task-sdk-node 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. @emilgroup/task-sdk-node on npm has been identified as a malicious package (versions 1.0.2, 1.0.3, 1.0.4 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
