Analysis

On module load the package downloads a platform-specific binary from attacker-controlled Cloudflare Workers endpoints (oob-work[.]er[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe, with a DNS TXT-record fallback channel via sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru. The fetched binary is written to /var/tmp/.cache_<hex> (or %TEMP%\dotnet_diag_<hex>.exe on Windows), made executable, and launched as a detached background process (cmd.exe start /b or /bin/sh -c '... &'). A cooldown lock file (.analytics_state) throttles re-execution. The package ships a large decoy analytics-SDK file alongside the loader.
