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.
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.
