185.104.63.91 has a threat confidence score of 97%. This IP address from Austria (AS25198, Interkvm Host Srl) has been observed in 543 honeypot sessions targeting TELNET protocols. First observed on April 29, 2026, most recently active April 29, 2026.
Telnet-based shell activity where the actor enumerates process execution context via cat /proc/self/cmdline (or equivalent) and performs directory navigation using cd. This pattern reflects post-access discovery behavior, where the session is inspecting runtime parameters and exploring filesystem layout to understand the execution environment before staging or executing additional actions. The combination indicates environmental reconnaissance rather than immediate payload deployment.
