91.231.89.176 has a threat confidence score of 72%. This IP address from France (AS213412, ONYPHE SAS) has been observed in 51 honeypot sessions targeting FTP, IMAP, SMTP, SSH, HTTP and 10 other protocols. First observed on January 20, 2026, most recently active March 22, 2026.
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.
FTP session where an empty control-channel command is observed in conjunction with non-printable binary data on the control channel. This pattern reflects malformed or non-FTP-compliant input, commonly seen during TLS handshake attempts on plaintext endpoints, protocol confusion, or automated scanner misfires.
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 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 TLS and then terminates the session with QUIT without performing further commands. This reflects minimal interaction limited to encryption negotiation and immediate disconnect, commonly observed in capability testing or automated probing.
