On require of the package, index.js loads compat.js, which at module load time downloads a platform-specific binary from hostnames assembled at runtime via string-splitting (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev). If HTTPS mirrors fail, it falls back to a DNS-over-TXT covert channel, resolving TXT records under *.dl.wel1.ru subdomains and base64-decoding the concatenated response into a binary. The fetched payload is written to a disguised path under /tmp or %TEMP% (e.g. dotnetdiag<hex>.exe,.cache<hex>), chmod 0755, and spawned detached via cmd.exe or /bin/sh -c with no hash or signature verification. Environment variable checks (DISABLETELEMETRY, ANALYTICSOPTOUT, DONOT_TRACK) and analytics-styled filenames provide cover. The destinations are not the publisher's infrastructure and the retrieval mechanism is inconsistent with any legitimate distribution channel.
