87.236.176.172 has a threat confidence score of 81%. This IP address from United Kingdom (AS211298, Driftnet Ltd) has been observed in 363 honeypot sessions targeting POSTGRES, HTTPS, MSSQL, SMTP, IMAP and 10 other protocols. First observed on January 21, 2026, most recently active March 17, 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.
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.
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.
FTP session where the client issues HELP, SYST, and FEAT commands to query supported commands, system type, and server capabilities before terminating the session.
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.
