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. dotnet_diag_<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 (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_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.
