It downloads a platform-specific native binary via https.get, writes it to /var/tmp/.cache_<rand> on Unix or %TEMP%\dotnet_diag_<rand>.exe on Windows to disguise the file, chmods it 0755, and spawns it detached via /bin/sh -c or cmd, then unref()s the child so it survives the parent. Cover-story comments ('Shuffle endpoints', 'analytics_state', a DISABLE_TELEMETRY opt-out) frame the dropper as telemetry. The destinations are attacker-controlled workers.dev/DDNS hosts, the delivered content is an opaque compiled binary unrelated to the package's advertised react-query purpose, and execution occurs on plain require() of the module.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
