Analysis

On require, the package runs a multi-stage dropper. It fingerprints the host platform/architecture, then downloads a binary payload over HTTPS from a rotating set of Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe depending on platform. If the HTTP download fails it falls back to a DNS TXT-record exfiltration channel via c[.]sdk[.]dl[.]wel1[.]ru (base64 reassembled from numbered TXT records). The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under %TEMP% on Windows), made executable, and launched detached via /bin/sh or cmd.exe start /b so it outlives the parent process. The payload is fetched and executed on every install/require unless DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, or DO_NOT_TRACK is set.
