Client sends RTSP OPTIONS requests to check supported methods and confirm that an RTSP service is exposed, then disconnects without attempting authentication or stream setup. This pattern is typically associated with automated reconnaissance or internet-wide scanning rather than active stream access.

FTP session where the client issues HELP, SYST, and FEAT commands to query supported commands, system type, and server capabilities before terminating the session.

Client repeatedly sends GET requests to the /bad-request Docker API endpoint, indicating malformed or incompatible traffic against the Docker daemon. This pattern is typically associated with generic internet scanning or tools attempting HTTP interaction without speaking the proper Docker API protocol.

Client performs a modern MongoDB handshake using the hello command followed by a buildinfo request to gather server capabilities and version details. This sequence is commonly associated with automated fingerprinting or discovery activity against exposed MongoDB instances rather than normal application queries.

Identifies execution of the Redis INFO command (case-insensitive), which retrieves server configuration, version, memory usage, and runtime statistics. This behavior reflects service interrogation and environment fingerprinting activity. While INFO can be used legitimately by administrators, it is also commonly observed during automated scanning and pre-exploitation reconnaissance of exposed Redis instances.
