Malicious code in @rutxploit-sec/waves-button-poc (npm)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

The declared main entry index.js repeats the same behavior at module top level, so any consumer that requires the package also beacons the same identifiers to the same IP. The scoped name and PoC framing are consistent with a dependency-confusion proof-of-concept, but the shipped code performs unauthenticated identifier collection from every installer regardless of intent, and the destination is an attacker-chosen bare IP over cleartext HTTP.
