Hostnames are hidden by splitting across array fragments joined at runtime. _shim.js downloads an opaque binary payload with no hash or signature verification, writes it to /tmp or %TEMP% under decoy filenames (dotnet_diag_<rand>.exe on Windows,.cache_<rand> on Unix), chmods it 0755, and spawns it detached via cmd.exe /c start or /bin/sh -c '<file> &'. A marker file analytics_state/.analytics_state is written, stderr logging is suppressed, and environment opt-outs (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) frame the dropper as telemetry. A dormant 81 KB lib/telemetry.js contains a parallel download-write-chmod-spawn code path with base64 payload reassembly, not currently referenced. The declared purpose of the package (a BNPL button UI component) does not require fetching or executing native binaries.
