MAL-2026-17696 Malicious code in @dransay/feature-flags (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.

@dransay/[email protected] publishes a scoped name on the public npm registry at an inflated version (99.0.0) designed to win semver resolution against any private internal @dransay/* copy. package.json declares a preinstall hook node beacon.js; beacon.js unconditionally performs a DNS lookup and HTTPS GET to the hardcoded interactsh callback host db3klhbi6i9hark1kegg174t38h33b6wt.oast.site on every npm install, leaking the installer's public source IP, a timestamp, and confirmation that the scoped name resolved from the public registry to a third-party out-of-band interaction collector. The README self-describes the artifact as a probe of DrAnsay build infrastructure; author self-labeling as research does not change the install-time behavior for any environment whose npm resolves @dransay/* publicly.
