MAL-2026-17698 Malicious code in @dransay/phone-fix-test (npm)

@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.

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.
