Malicious code in @dransay/phone-fix-test (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.

@dransay/[email protected] is a dependency-confusion probe claiming the internal `@dransay/*` namespace, 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 the package name in the request; npm account `0xamino_hunter` published it on 2026-10-08. --- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (e01479e9a6af5de5f6abec6c16007bd3757b52b0e434b38b44d40fde12961c08) Package.json declares scripts.preinstall="node beacon.js", which fires automatically on npm install. beacon.js performs a DNS lookup and HTTPS GET to a hardcoded Interactsh/OAST subdomain under oast.site, keyed on the package name, causing the installing host's source IP and resolver metadata to be logged by a non-first-party collector. The package is published under the @dransay scope on the public npm registry at version 99.0.0 — the standard dependency-confusion probe shape (scoped name matching a target organization, implausibly high version to win resolution against an internal package of the same name). Any build system that resolves @dransay/phone-fix-test from public npm will execute the preinstall callout and leak its network identifier to the researcher's OAST endpoint. The README self-labels the behavior as authorized security research, but a self-label does not change the installer-side effect: unconsented install-time exfiltration of host-identifying network metadata to a researcher-controlled collector.
