Malicious code in internallib_v23 (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.

--- _-= Per source details.

The destination is a hardcoded private-range IP, there is no authentication, no documentation of the behavior, and the fetched content is executed directly. The package's only exported functionality is this backdoor dropper.
