On any require() of this package, index.js loads loader.js, which reconstructs destination hostnames at runtime from array-join fragments (oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, with DNS-TXT fallbacks under *.dl.wel1.ru), downloads a platform-specific binary from those hosts, writes it to /tmp or %TEMP% under masquerading filenames such as dotnetdiag_*.exe or.cache_*, chmods it 0755, and spawns it detached via cp.spawn("/bin/sh", ["-c", fp+" &"], {detached:true}) or spawn("cmd",...). A second, parallel dropper is bundled in lib/telemetry.js: a base64-decoded payload buffer is written, chmod'd 0755, and executed via detached /bin/sh. childprocess and hostname strings are assembled with require("child"+"process") and [...].join("") to evade static analysis. The opaque remote payload has no hash or signature verification and originates from non-publisher Cloudflare Workers infrastructure.
