The destination hostnames are constructed by string-splitting and joining at runtime to evade static analysis. The fetched bytes are written to /var/tmp/.cache_<hex> on POSIX or %TEMP%\\dotnet_diag_<hex>.exe on Windows (a name mimicking a Microsoft diagnostic tool), chmod 0755'd, and spawned detached via /bin/sh -c or cmd /c start. Opt-out variables and file naming are framed as 'analytics'/'telemetry' while the actual behavior is fetch-and-execute of an unpinned, unverified opaque native binary. A second file, lib/telemetry.js, is shipped in the tarball with the same fetch-decode-chmod-spawn primitives using concatenated API names ('child_'+'process', 'chmod'+'Sync') as a companion payload.\n\n## Source: ghsa-malware (407a5375877220239a322683461f343d08a1566ebd5ba3c0b8056af2729f8bb3)\nAny computer that has this package installed or running should be considered fully compromised.
