2001:41d0:33a:a00::403 has a threat confidence score of 82%. This IP address from France (AS16276, OVH SAS) has been observed in 170 honeypot sessions targeting REDIS, SSH, SIP, SMTP, HTTPS and 13 other protocols. First observed on January 21, 2026, most recently active March 20, 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.
Automated SMTP interaction performing a minimal capability check by issuing EHLO followed by a STARTTLS upgrade request and immediately terminating the session. This pattern is commonly associated with internet-wide scanners, security research crawlers, or opportunistic bots verifying whether an SMTP service supports encrypted communication. The absence of authentication attempts or message submission indicates reconnaissance or service fingerprinting rather than active abuse.
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
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.
