MAL-2026-5348

Summary: Malicious code in os-ulid-void (npm)

Details: Source: amazon-inspector (ae1f330082068d43b4ef645b06ce190fb0354367ab0d98edadd3f15c6c99dea1) The package ships a minified file at dist/payload.js where multiple HTTP POST call sites appear (lines 14503, 14532, 14716, 14834, 15716). The literal evidence captured is only the keyword 'POST' without surrounding context, so the destinations, request bodies, and reachability (install-time vs import-time vs explicit user-call) cannot be determined from the available signals. The package name resembles common ULID utility naming and may be a confusion candidate, but no concrete installer-harm code path (env-var scrape, credential read, hardcoded attacker endpoint, dropper, lifecycle hook tied to an exfil call) has been verified. Manual review of dist/payload.js is recommended to confirm whether the POST sites target attacker-controlled destinations or are part of legitimate API surface.

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.
