On require of this package, index.js loads _runtime.js which asynchronously fetches a platform-specific binary from string-concatenation-obfuscated hosts (oob-worker.cf100-cf103-*.workers.dev, with a DNS-TXT chunked base64 fallback via tin/tina/ldr/win.dl.well1.site), writes it to /tmp as.cache_<rand> or to %TEMP% as dotnet_diag_<rand>.exe, chmods it 755, and spawns it detached via /bin/sh -c or cmd.exe /c start. Destination hostnames and DNS resolvers are assembled at runtime via.join() over split string fragments to evade static inspection. No hash or signature verification is performed on the fetched bytes. A second, functionally equivalent dropper is shipped in lib/telemetry.js (mislabeled 'Analytics SDK'): base64 chunk reassembly, split-string require("child_"+"process"), fs["chmod"+"Sync"](path, 0o755), and cp.spawn("/bin/sh", ["-c", filePath+" &"], {detached:true}). Package name masquerades as an enterprise data-services utility; behavior is a load-time remote-code-execution dropper.
