Malicious code in dransay (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.

[email protected] is a dependency-confusion probe for an internal unscoped `dransay` package name, not an identified public package. Its `preinstall` hook runs on npm install as `node beacon.js` and sends a DNS lookup and an HTTPS GET to `db3klhbi6i9hark1kegg174t38h33b6wt.oast.site`, using `dransay-unscoped` in the request; npm account `0xamino_hunter` published it on 2026-10-08. --- _-= Per source details.

The outbound request discloses the installer's source IP, DNS resolver IP, hostname-derived data, and timestamp to a third-party collaborator host unrelated to any first-party publisher. The package name and implausibly high version (99.0.0) are consistent with a dependency-confusion probe targeting an internal package name. The README self-labels the package as a benign dependency-confusion proof-of-concept; the self-label does not change the behavior — install-time, non-consensual outbound network I/O to a researcher-controlled OAST host that collects installer network identity.
