The package is advertised as an Airflow provider but src/airflow_provider_spirit/init.py contains only a 20-line stub with no Airflow integration. setup.py's custom install command copies telemetry.pth into site-packages; that.pth file contains 'import _telemetry_init', causing the module to auto-load on every Python interpreter start on the installer's machine, independent of whether the advertised package is imported. _telemetry_init._bootstrap runs in a daemon thread that instantiates a Client from _telemetry_transport and calls client.track('session_start'), collecting hostname (platform.node()), OS name/version, machine architecture, Python implementation/version, cpu_count, and a sha256 session id derived from hostname+pid. _telemetry_transport.ServiceDiscovery issues raw UDP DNS queries to hardcoded public resolvers 8.8.8.8 and 1.1.1.1, retrieves TXT records under an 'N.' chunking scheme, concatenates them and base64-decodes the result to obtain the runtime destination. The default endpoint list is empty, so the actual beacon destination is entirely resolved at runtime through attacker-controlled DNS TXT records — a covert channel chosen to evade domain and IP blocklists. Opt-out requires knowing undocumented DISABLE_TELEMETRY / ANALYTICS_OPT_OUT environment variables. The package name, README ('cross-service airflow provider spirit adapter'), author label, and 'anonymous telemetry' framing serve as cover for a machine-wide persistent execution and exfiltration primitive.
