Malicious code in boxy-lcd (npm)

The package's index.js top-level requires setup.js, which on load fetches an OS-specific executable from string-concat-obfuscated Cloudflare Workers hosts (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev) and additional hosts under dl.wel1.ru (sdk./ext./pkg./net.), with a DNS-TXT base64 fallback channel. The fetched bytes are written to a hidden temp path with masquerading names such as.cache<hex> and dotnetdiag<hex>.exe, chmod 0755, and spawned detached via /bin/sh or cmd. Network destinations and the childprocess require string are assembled at runtime from split literals to evade static analysis; the exported BoxyLcd class is a non-functional stub, and opt-out env vars are named to resemble legitimate telemetry (analyticsstate, DISABLETELEMETRY). Any consumer that installs or requires boxy-lcd triggers download-and-execute of an opaque, author-controlled binary on the installer's host.
