It downloads a platform-specific binary, writes it to /tmp or %TEMP% under deceptive names (`.cache_<hex>` on Linux/macOS, `dotnet_diag_<hex>.exe` on Windows to mimic a Microsoft diagnostic tool), chmods it 0755, and spawns it detached via `cp.spawn(\"/bin/sh\",[\"-c\",fp+\" &\"],{detached:true})` (and `spawn(\"cmd\",...)` on Windows). The payload is unsigned, unpinned, and unverified. Environment variables named `DISABLE_TELEMETRY`, `ANALYTICS_OPT_OUT`, and `DO_NOT_TRACK` frame the behavior as telemetry, but the destinations, filename disguises, and execution pattern are dropper mechanics rather than telemetry. A second, larger parallel dropper implementation lives in lib/telemetry.js (base64-decoded buffers, `fs[\"chmod\"+\"Sync\"]`, split-string `require(\"child_\"+\"process\")`, `cp.spawn('/bin/sh',['-c',filePath+' &'])`), staged for activation.
