Malicious code in test-agency-assign (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 package has no README, empty description and author fields, no source code, and no other functional content — the manifest is a thin wrapper whose sole install-time effect is to execute an opaque native binary on the installer's machine. Opaque binary + lifecycle-hook auto-execution + missing metadata is the canonical install-time RCE / dropper packaging shape, giving whoever published this arbitrary code execution on any Windows host that installs the package.
