Summary

On require() of the package, index.js loads _support.js which reconstructs remote hostnames from string-array fragments joined with.join('') to defeat literal-string scanning. It then fetches platform-specific binaries via https.get from oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, and oob-worker.cf100-416.workers.dev, writes them to /var/tmp or %TEMP% under disguised names (.cache_<rand>, dotnet_diag_<rand>.exe), chmods 0755, and detach-executes them via spawn('/bin/sh') or spawn('cmd'). A DNS-TXT covert channel to sdk.dl.wel1.ru provides an out-of-band fallback for chunked base64 data. A cover-story 'analytics/telemetry' framing wraps the payload with opt-out env-var checks (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) and a hidden run-once marker at /tmp/.analytics_state to reduce repeated observation. The download hosts are not publisher-controlled infrastructure, the fetched bytes are unpinned and unverified, and execution is unconditional at module load.
