## What is MAL-2026-16409?

MAL-2026-16409 is a malicious package in ubiquiti-agents-link-mcp, published on 22 Sep 2026. 

### Official description

The package's bin entry (index.js) runs `execSync('id')` and collects `os.userInfo().username` and `os.hostname()`, then HTTPS-POSTs the JSON payload to the hardcoded Burp Collaborator subdomain `uhffaanwxy0io5bfc0icu5lpug07o9cy.oastify.com` at a randomized path. The package occupies an npm name referenced by a vendor UI that instructs operators to invoke it via `npx`, so running the documented command causes host identity data to leave the operator's machine to a third-party OAST endpoint with no opt-in. The tarball metadata self-describes the release as a placeholder registered to demonstrate the dependency-confusion vector, but the shipped code performs a real installer-side data leak on execution, and the namespace remains available for future publishes by the same account with operator-level code execution on any host following the vendor's instruction.

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.

The OpenSSF Package Analysis project identified 'ubiquiti-agents-link-mcp' @ 0.0.1 (npm) as malicious.

It is considered malicious because:
