Analysis

Multi-stage binary dropper. On require(), the package fingerprints the OS and architecture, then downloads a platform-specific binary payload from Cloudflare Workers C2 infrastructure (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev) via HTTPS GET to /pkg/package (linux_x64), /pkg/package-arm64 (linux_arm64), /pkg/loader_mac (darwin), or /pkg/package.exe (win32). If HTTPS download fails, it falls back to a DNS TXT-based chunked transfer channel via c[.]tin[.]dl[.]well1[.]site (and platform-specific subdomains tina[.]dl[.]well1[.]site, ldr[.]dl[.]well1[.]site, win[.]dl[.]well1[.]site). The downloaded binary is written to /var/tmp/.cache_<random> (Unix) or %TEMP%\dotnet_diag_<random>.exe (Windows) and executed as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c "file &" on Unix). A cache marker at /tmp/.analytics_state prevents re-download within ~6 hours.
