Remote client performs MongoDB service validation and environment fingerprinting by first initiating a wire-protocol handshake (ismaster / hello) followed by execution of the buildInfo command against the admin database. This sequence indicates targeted reconnaissance to determine server role, software version, build characteristics, and platform details. Such activity is commonly associated with automated scanning frameworks and pre-exploitation tooling used to assess exposure and identify version-specific vulnerabilities prior to authentication attempts or database enumeration

Identifies RDP clients attempting authentication using the legacy RDP security mode where credentials are exchanged through the older RDP security layer instead of Network Level Authentication (NLA). This indicates the client negotiated legacy plaintext authentication during the RDP security handshake

RTSP OPTIONS request targeting /multicast/profile2/media.smp, indicating capability probing of a multicast camera stream endpoint commonly associated with IP camera profiles and observed in automated scanning activity.

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 an automated Redis service probing sequence consisting of PING, INFO (uppercase invocation), execution of a deliberately nonexistent command to assess error handling behavior, and QUIT. This tightly grouped pattern reflects reconnaissance and fingerprinting activity used by scanners and exploitation frameworks to determine Redis version, configuration details, and command availability prior to follow-on exploitation attempts. The inclusion of a nonexistent command indicates capability probing rather than normal client interaction.

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.

HTTP request using GET method.

FTP session where the client issues AUTH TLS to upgrade the connection to Transport Layer Security. This reflects protocol-level encryption negotiation prior to further interaction.

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

Identifies HTTP GET requests directly targeting the /bad-request path, indicating automated or manual probing of application error-handling routes rather than legitimate navigation flow.
