Details
The package advertises itself as a reactive state-management library but its index.js silently requires./setup at the end of module load inside a try/catch. setup.js schedules a next-tick bootstrap that collects a host fingerprint (os.hostname(), os.userInfo().username, process.cwd(), pid, platform, arch), derives an installId, and loads a ~76KB lib/telemetry.js runtime that POSTs data via https.request. The identifier reads are obfuscated via string-concatenation indirection (os["host"+"name"](), os["user"+"Info"](), os["plat"+"form"](), and a helper const _p=(k)=>os[k]()), which is not consistent with legitimate telemetry SDKs. The destination host is not present as a plain literal in telemetry.js; the file imports dns and https and contains a ServiceDiscovery class that resolves the endpoint at runtime, hiding the exfiltration target from source inspection. Nothing in the advertised state-store API references telemetry, and no opt-in or configuration surface is exposed.
