173.255.229.76 has a threat confidence score of 98%. This IP address from United States (AS63949, Akamai Connected Cloud) has been observed in 311 honeypot sessions targeting SSH, REDIS, HTTP, SMTP, HTTPS and 5 other protocols. First observed on January 22, 2026, most recently active April 5, 2026.
Identifies the use of SCP in quiet mode (-q) with “to” mode (-t), indicating the remote system is receiving a file. This pattern is commonly associated with post-authentication payload delivery, lateral movement staging, or tool transfer to a compromised host.
FTP session where a client probes for valid usernames, attempts authentication, switches to ASCII mode, and enters passive mode without performing explicit file listing or transfer operations. This reflects a completed login and session setup sequence, often observed during credential validation or preparatory access prior to further activity.
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 HTTPS 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.
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.
