66.132.172.104 has a threat confidence score of 90%. This IP address from United States (AS398324, Censys, Inc.) has been observed in 35 honeypot sessions and reported 1 times targeting HTTP, HTTPS, IMAP, SMTP, SIP and 5 other protocols. First observed on March 20, 2026, most recently active March 23, 2026.
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 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 HTTPS requests targeting the web server root path ("/"), typically used for initial service discovery, host validation, or baseline content inspection prior to deeper enumeration
SMTP interaction identified as an internet-wide scanning probe originating from Censys infrastructure. The client announces itself via EHLO www.censys.io and issues a STARTTLS request to verify TLS upgrade support and collect service capability metadata. This pattern reflects automated reconnaissance and exposure mapping rather than direct exploitation, but still represents active external probing of the SMTP service.
