The bytes are written to /tmp/.cache_<rand> or %TEMP%\\dotnet_diag_<rand>.exe, chmod 0755, and spawned detached via /bin/sh -c or cmd /c start /b. Hostnames are assembled from split string arrays (e.g. [\"oob-worker.cf99-9b3.wor\",\"kers.\",\"dev\"].join(\"\")) to evade substring scans, and file names (analytics_state, dotnet_diag) masquerade as diagnostics artifacts. A telemetry-styled opt-out gate (DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK) frames the download-and-execute as consented telemetry, but the default path is unconditional remote code execution. No hash or signature verification is performed; the URL is mutable and anonymous. The package name resembles a UI select component but its only observable behavior on import is the dropper.\n\n## Source: ghsa-malware (9c3519c1c22bb4eab75836d741089a70981c2909eea8323132d4424fb338f929)\nAny computer that has this package installed or running should be considered fully compromised.
