3.143.33.63 has a very high threat confidence level of 100%, originating from Columbus, United States, on the Amazon.com, Inc. network (16509). It has been observed across 6,238 sessions targeting SMTP, RTSP, REDIS, HTTPS, HTTP and 12 other protocols, First observed on January 20, 2026, most recently active February 4, 2026.
Client performs initial MongoDB discovery using isMaster followed by listDatabases and buildinfo, indicating active enumeration of server structure and version details. This pattern goes beyond basic probing and reflects an attempt to map available databases on an exposed instance.
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.
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 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.
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.
