TCL 雷鸟电视尝试登陆路由器？

昨晚 switch 到货了，开电视玩了一会。刚刚无意中发现路由后台有大量的 root 用户登录失败记录，内网 ip 是雷鸟电视的。 贴一下部分日志 Thu May 6 22:30:31 2021 authpriv.info dropbear[631]: Child connection from 192.168.233.154:56798 Thu May 6 22:30:31 2021 authpriv.info dropbear[631]: Exit before auth from <192.168.233.154:56798>: Exited normally Thu May 6 22:31:09 2021 authpriv.info dropbear[2628]: Child connection from 192.168.233.154:56880 Thu May 6 22:31:09 2021 authpriv.warn dropbear[2628]: Login attempt for nonexistent user Thu May 6 22:31:10 2021 authpriv.info dropbear[2628]: Exit before auth from <192.168.233.154:56880>: Client trying multiple usernames Thu May 6 22:31:10 2021 authpriv.info dropbear[2637]: Child connection from 192.168.233.154:56882 Thu May 6 22:31:10 2021 authpriv.warn dropbear[2637]: Bad password attempt for 'root' from 192.168.233.154:56882 Thu May 6 22:31:10 2021 authpriv.warn dropbear[2637]: Bad password attempt for 'root' from 192.168.233.154:56882 Thu May 6 22:31:11 2021 authpriv.warn dropbear[2637]: Bad password attempt for 'root' from 192.168.233.154:56882 Thu May 6 22:31:11 2021 authpriv.info dropbear[2637]: Exit before auth from <192.168.233.154:56882>: (user 'root', 3 fails): Max auth tries reached -
