What this malware does

src/index.js imports child_process and issues POST requests alongside a ping command invocation (lines 25, 38, 49). The co-occurrence of child_process shell execution with hardcoded network POST endpoints and a system ping in a package presenting itself as a Google Contacts integration piece is inconsistent with the declared purpose (an OAuth-based Google Contacts API client would not need to spawn shell processes or ping remote hosts). The pattern matches host reconnaissance and outbound beaconing shape rather than legitimate Google People API interaction.

Detection & response playbook

Backdoor / remote access

  1. Find it

    Search your lockfiles and build artifacts for @activepieces/piece-google-contacts (2 malicious versions).

  2. If you installed it — respond

    @activepieces/piece-google-contacts establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

  3. Did it already run?

    If @activepieces/piece-google-contacts 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. @activepieces/piece-google-contacts on npm has been identified as a malicious package (versions 0.4.7, 0.4.8 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
