## What is MAL-2026-6987?

MAL-2026-6987 is a malicious package in @luminarycloudinternal/lcvis-st, published on 8 Jul 2026. 

### Official description

Package @luminarycloudinternal/lcvis-st@9999.0.2 is published to the public npm registry under an internal-looking scope with an artificially high version number designed to outrank any legitimate internal release, so misconfigured installers resolve this public copy. On install, the postinstall.js script collects host and user identifiers (os.hostname(), os.userInfo().username, OS type/release/platform/arch), npm package name/version and user-agent, and CI/GitHub identifiers (CI, GITHUB_ACTIONS, GITHUB_REPOSITORY, RUNNER_NAME, GITHUB_SHA, GITHUB_REF, GITHUB_WORKFLOW), then sends them as query parameters via HTTPS GET to a hardcoded third-party endpoint at poc-luminary-npm-1782987043.testingboxes.com (postinstall.js line 34). The package self-labels as a Bugcrowd bounty canary, but the behavior — dependency-confusion scope/version combined with install-time transmission of installer identifiers to a hardcoded third-party host — is exfiltration for any installer other than the intended bounty target.

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.

## What should I do about MAL-2026-6987?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
