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

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