Summary

Malicious code in @luminarycloudinternal/frodo (npm)

Details

Package published under a scope shadowing internal Luminary Cloud packages (@luminarycloudinternal) at version 9999.0.1 — the canonical dependency-confusion shape designed to win version resolution over a private internal package of the same name. On install, postinstall.js (line 8) performs an HTTPS GET to a hardcoded external host (poc-luminary-npm-1782987043.testingboxes.com) carrying installer-owned CI and host identifiers: GITHUB_REPOSITORY, GITHUB_SHA, GITHUB_REF, GITHUB_WORKFLOW, RUNNER_NAME, os.hostname(), and npm user-agent. When a build system misresolves the internal name to the public registry, this postinstall runs automatically and discloses internal repository, workflow, commit, and runner identifiers to a third-party endpoint. The package self-identifies as a Bugcrowd research canary, but self-labeling does not change the mechanism: installer-owned metadata leaves the machine at install time to a non-first-party destination via a namespace-squat. ## Source: ghsa-malware (9a690eb1bc2a09fccfb06b9531bbd7ec4da297737e700bd165096270b54c9995) 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.

Independent LPM AI assessment

Suspicious

Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree.

Source inspection confirms automatic install-time host/CI fingerprint exfiltration to an external endpoint for a dependency-confusion canary. Even without credential theft, persistence, or destructive actions, this is concrete unconsented install-time data exfiltration from environments resolving an internal-looking package name. Product guard normalized a non-low false-positive publish_block request to warn-only suspicious.

Static reason

One or more suspicious static signals were detected.

Trigger

npm install runs package postinstall lifecycle

Impact

Leaks package, npm user agent, CI/repo metadata, hostname, username, and OS details to an external endpoint

Mechanism

install-time host and CI fingerprint exfiltration via HTTPS GET

Independent scan evidence

public snapshot

AI called this Suspicious at 93.0% confidence as Malware with medium false-positive risk.

Evidence for AI warning decision

package.json defines install-time postinstall: node postinstall.js
postinstall.js sends HTTPS GET to external testingboxes.com endpoint during install
postinstall.js collects host/user/OS plus CI repo, runner, sha, ref, workflow env identifiers
postinstall.js suppresses errors and never fails install

Evidence against

No child_process, shell execution, eval, dynamic require, or native/binary loading found
No file reads/writes or persistence found beyond executing postinstall.js
README/package comments describe it as a dependency-confusion canary
