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

Remote client performs structured MongoDB reconnaissance by initiating a wire-protocol handshake (ismaster / hello), executing the buildInfo command to obtain server version and build characteristics, and subsequently issuing listDatabases to enumerate all databases present on the instance. This sequence reflects systematic service validation and environment mapping activity commonly associated with automated internet-wide scanning, vulnerability assessment tooling, or pre-exploitation reconnaissance workflows.

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 Redis service discovery and basic environment enumeration where an actor probes with invalid commands, validates availability using PING, retrieves server metadata via INFO (case variations), and gracefully exits with QUIT. This pattern is commonly used to fingerprint exposed Redis instances before exploitation.

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.

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.

HTTP request using GET method.

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
