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 HTTP 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.

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
