Los troyanos


Los troyanos son un código malicioso que nos puede causar mucho daño si se cuelan en nuestro sistema. Para entender por qué se les llama troyanos, tenemos que recordar un poquito al caballo de Troya. Como sabéis, los griegos no podían superar el bloqueo de la ciudad de Troya, y para entrar ingeniaron un caballo de madera que parecía totalmente inofensivo, que regalaron a los Troyanos, y éstos, sin ver ningún peligro en ello, metieron en su ciudad. El caballo estaba lleno de soldados, que, por la noche, mientras los Troyanos dormían, salieron y abrieron las puertas de la ciudad, lo cual supuso la perdición para el pueblo de Troya.

 

 

Pues los programas con Troyanos son lo mismo. Son programitas, en apariencia normales, muy cucos ellos, pero que parte del código del programa no se dedica a loq ue nosotros creemos que se dedica ese programa, sino que se dedicaa sacar datos de nuestro sistema, abrir puertos para que puedan acceder desde fuera, etc.


 

¿Cómo detectar sus síntomas?

Algunos síntomas de nuestro sistema pueden alertarnos de que tenemos un troyano, como pro ejemplo:

 

  • El router o disco duro actúan anormalmente, parecen estar con mucha actividad aunque no estemos haciendo nada.
  • Se nos bloquea todo constantemente.
  • El ratón va a golpes y a ratos no responde.
  • Se nos cierran o abren programas inesperadamente.

 


¿Que hacer para combatirlos?

Lo mejor es tener un buen cortafuegos. Los hay gratuitos y que van muy bien. Lo importante es que se bloqueen los puertos que usan para sacar la información, o para acceder desde fuera. Si hemos instalado el cortafuegos cuando ya hemos sido infectados, el cortafuegos nos pedirá confirmación cada vez que el sistema quiera sacar o dejar entrar información por puertos sospechosos.

Sobre todo, no abrir archivos ejecutables que nos envían por correo electrónico, si no son fiables. sobre todo los que nos vienen por spam.


Aquí tenéis la lista de los troyanos y los puertos que utilizan.
