MAL-2026-17427 Malicious code in ai-workshop-maa15-radio (npm)

ai-workshop-maa15-radio is a dependency-confusion package: it takes a name that looks like an internal project, uses an inflated version (100.0.0) so it outranks private-registry versions, and runs node setup.js || true as a preinstall script on npm install. setup.js sends the hostname, username, working directory, OS, architecture, Node.js version and configured npm registry, with a per-package tracking token, in an HTTPS POST to https://s85r5k14qk.execute-api.us-east-1.amazonaws.com/prod/hook. The npm account amel10 published ai-workshop-maa15-radio and 9 similar packages within two minutes on 2026-09-30, all with the same setup.js.

Package advertises itself as a trivial string helper (reverseWords) but its declared preinstall script (node setup.js) opens an HTTPS POST to a hardcoded endpoint at s85r5k14qk.execute-api.us-east-1.amazonaws.com/prod/hook on every npm install. The request body contains os.hostname(), os.userInfo().username, process.cwd(), os.platform(), os.arch(), process.version, and npm_config_registry, along with a hardcoded per-package tracking token. The version number (100.0.0) and the collection of npm_config_registry are consistent with a dependency-confusion reconnaissance beacon targeting internal package resolution. Installer host and user identifiers are transmitted to an attacker-controlled endpoint without consent, fired automatically at install time.
