#1 Ataque fuerzabruta a travez puerto 22 SSH Bueno mientras miraba television me percato de que hay una alta actividad de red en mi equipo a travez de Conky, observando mas detalladamente veo que son conexiones a travez del puerto ssh (Tengo configurado Conky para que me informe estas conexiones), en las cuales veo que eran entre 1 y 2 simultaneas.
Inmediatamente (cual pelicula de ciencia ficcion) y cegado por la paranoia desconecto el cable de red, cierro el servicio ssh y analizo el archivo /var/log/messages
aqui les dejo adjunto el archivo TXT con la salida del comando $cat /var/log/messages | grep sshd
Es interesante ver como utiliza el metodo de diccionario (en este caso de nombres) para tratar de establecer la conexion. Aunque mi USER no sale en el diccionario, cabe destacar aqui la importancia de una contraseña segura (www.passwordmeter.com sacando aqui 100% seguridad.) para impedir que estos ataques lleguen a un exito.
haciendo un whois a las ips de donde provienen los ataques obtengo
$ whois 201.6.106.248 Brazil
CONCLUSION
Tanto en mis pcs, como en los routers con ddwrt (linux) voy a cambiar varios users y passwords haciendolos mas seguros, tambien cambiare los puertos ssh y en los routers voy a desactivar el portfowarding, habilitandolo remotamente cuando sea necesario.
Quiero aclarar aqui que esta posibilidad de ataques de multiples locaciones, puede deberse a que tengo un servicio DDNS sobre mi direccion ip. Asi que con un simple ataque al URL obtienen la ip

CONCLUSION
Tanto en mis pcs, como en los routers con ddwrt (linux) voy a cambiar varios users y passwords haciendolos mas seguros, tambien cambiare los puertos ssh y en los routers voy a desactivar el portfowarding, habilitandolo remotamente cuando sea necesario.
Quiero aclarar aqui que esta posibilidad de ataques de multiples locaciones, puede deberse a que tengo un servicio DDNS sobre mi direccion ip. Asi que con un simple ataque al URL obtienen la ip
