SIP request using sip:nm as the Request-URI, a malformed or placeholder target commonly observed in SIP scanning and fuzzing activity rather than legitimate client behavior.

Client requests RTSP OPTIONS followed by DESCRIBE to query supported methods and retrieve stream metadata, but does not proceed to session setup or playback. This pattern is commonly associated with automated scanning or reconnaissance activity checking for exposed cameras or media services.

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.

Identifies HTTPS requests targeting the web server root path ("/"), typically used for initial service discovery, host validation, or baseline content inspection prior to deeper enumeration

HTTPS request to /robots.txt.

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.

Identifies HTTP requests targeting the web server root path ("/"), typically used for initial service discovery, host validation, or baseline content inspection prior to deeper enumeration.
