A fallback loadViaDns routine retrieves the payload as chunked base64 from TXT records under *.dl.wel1.ru (a count is read from c.<domain>, then N sequential TXT records are concatenated and base64-decoded). Marker-file single-execution gating and TELEMETRY/DO_NOT_TRACK environment-variable kill switches are present to suppress re-execution and evade observation.\n\n## Source: ghsa-malware (cb9e41b3bac04f947a3e2a78e7577139d97179455d503fe8bee0cfd116cf458e)\nAny computer that has this package installed or running should be considered fully compromised.
