Source: amazon-inspector (c4fa9effd850891eced167c6313a3e722c359890792d59446d9f28f7898bd4a0)

On require of the package's main entry, shim.js and lib/telemetry.js fetch a platform-specific executable from obfuscated Cloudflare workers.dev endpoints (oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev) with a DNS-TXT fallback to sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, base64-decode the response, write it to /tmp/.cache<hex> on Unix or %TEMP%\dotnetdiag<hex>.exe on Windows, chmod 0755, and spawn it detached via cp.spawn("/bin/sh", ["-c", filePath + " &"], {detached:true, stdio:"ignore"}). Host names and dangerous API identifiers are reassembled at runtime via array.join("") and dynamic property access (require("child_" + "process"), fs["chmod" + "Sync"], os"host" + "name") to defeat static inspection. The dropper logic is duplicated between _shim.js and lib/telemetry.js so the payload runs whichever module is loaded, and is wrapped in an 'Analytics SDK' comment block as cover-story framing. Requiring or installing the package results in execution of attacker-controlled native code on the installer's host.
