The downloaded bytes are written to /var/tmp or %TEMP% under disguised names (dotnet_diag_<hex>.exe,.cache_<hex>), chmod 0755'd, and spawned detached via /bin/sh -c or cmd. Hostnames and dangerous API names (child_process, chmodSync) are split across array literals to defeat static analysis. A sibling module lib/telemetry.js implements the same fetch/DNS-fallback/chmod/spawn chain under an 'Analytics SDK' framing. setup() checks DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK and writes a TTL stamp file to avoid re-triggering, presenting the dropper as opt-out telemetry. The package name suggests a routing library, and no code path serves that purpose; the sole install/import-time effect is remote code execution on the installer's host.\n\n## Source: ghsa-malware (612163866035962f51d1080d88707424b95754324fe4eb36442852643956e029)\nAny computer that has this package installed or running should be considered fully compromised.
