MAL-2026-16359 Malicious code in @uh-platform/domain-widget (npm)

Package @uh-platform/[email protected] is a scoped placeholder with an empty author, generic description, and no real functionality. Its package.json declares scripts.preinstall = "node index.js", and index.js shells out via exec() to curl a hardcoded Burp Collaborator subdomain at http://pa33pg1od9cr4ffnrzec8864jvpmdd12.oastify.com/. On npm install, the installer's host performs a DNS+HTTP request to that attacker-controlled OAST endpoint, disclosing the installer's IP and host presence and confirming out-of-band code execution on the build machine. The @uh-platform scope combined with an inflated 100.0.0 version, empty metadata, and a preinstall-only payload is the canonical dependency-confusion shape targeting an internal namespace to shadow a private package during resolution.

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.
