MAL-2026-5880

Summary: Malicious code in nat-ulid (npm)

Details: Source: amazon-inspector (ab95c3f95c377215b7cbd4be6d2cdcc79304910b03a2dcdf08f65da6f1c05f4c) The package ships a bundled file at dist/node/payload.js containing several POST call sites (around lines 14592, 14621, 14805, 14923, 15805). Pattern matches alone cannot distinguish a legitimate HTTP client library from an exfiltration channel: the destinations may be configurable parameters of an exposed API, documented vendor endpoints, or attacker-controlled hosts. No corroborating behavior such as credential reads, environment scraping, install-time lifecycle execution, or known-bad infrastructure was identified in the available evidence. Routing to human review for semantic verification of the bundle's POST destinations and reachability.

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.
