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 execution of the Redis INFO command (case-insensitive), which retrieves server configuration, version, memory usage, and runtime statistics. This behavior reflects service interrogation and environment fingerprinting activity. While INFO can be used legitimately by administrators, it is also commonly observed during automated scanning and pre-exploitation reconnaissance of exposed Redis instances.
