212.21.136.181 has a threat confidence score of 79%. This IP address from Bulgaria (AS44247, Videosat 21 Vek OOD) has been observed in 3 honeypot sessions targeting TELNET protocols. Detected attack patterns include telnet busybox shell activation with capability check, telnet busybox multi method payload retrieval and execution. First observed on February 17, 2026, most recently active February 20, 2026.
Identifies a Telnet session where BusyBox is leveraged to activate or access a shell environment (sh, shell, system, linuxshell, enable) followed by command capability validation (ping). This pattern reflects deliberate shell breakout and execution-context validation commonly observed in IoT botnets and embedded Linux compromise workflows. The presence of multiple shell invocation variants combined with BusyBox applet usage indicates adaptive execution logic rather than incidental command usage.
Identifies a Telnet session where an attacker leverages BusyBox utilities to retrieve a remote payload using one or more file transfer mechanisms (e.g., wget, curl, ftpget, or tftp) followed by execution of the downloaded script via sh. This pattern is consistent with IoT botnet propagation and automated malware deployment.
