Port check tool

The ports that allow us to communicate with different servers throughout our daily Internet browsing can generate some problems if the amount of information exceeds the limit or gets dangerously close to them.

When you send a series of requests to the Internet while you are using an application and the ports you need to generate a correct connection are not open, you will start having a series of problems to connect.

From this concept it becomes clearer why it is necessary to generate rules to open more ports that allow a fluid data traffic and that allows us to perform our activities without major problems.

You must be aware of port management, create rules to open one or a range of ports and when you stop using them, close them to avoid penetration by attackers and prevent information theft or a virus or spyware from sneaking in.

Sometimes the traffic is heavy and since Izzi handles private IPs, our packets can take longer than necessary or get lost on the way when thousands of requests are detected at the same time, which sometimes results in a slow internet or practically no connection at all.

Whether it is to use applications or enjoy online games, in many occasions we need to manipulate the router’s ports, for those who have VTR Internet it can be quite complicated. However, we are going to show you how to open the ports of your Arris VTR router in a very simple and fast way, follow this article step by step and you will quickly get results.

Before opening the ports of a router, it is necessary to configure our computer with a static or fixed IP address so that this IP always belongs to the same computer, otherwise, if another computer is assigned this IP, the ports will be opened for him and not for us.

Universal Plug and Play, also known as UPnP, is a set of protocols thanks to which several devices within the network, and facing the WAN, are able to communicate with each other freely without the need to specify the ports that can be accessed by each one.

Hace un par de meses, unos amigos me invitaron a dar una charla en la Conferencia de Seguridad NullByte. Me puse a estudiar sobre algunos temas candentes de hacking basura de dispositivos embebidos y decidí hablar sobre la seguridad de los cablemódems. Braden Thomas dio una charla en Infiltrate 2015 hablando sobre Ataques Prácticos a DOCSIS así que, sí, el hacking de módems de cable sigue siendo la corriente principal.

El 21 de noviembre estaré en Salvador hablando sobre «Hacking de módems de cable: Los últimos años». No es una charla sobre el robo del servicio y la obtención de acceso gratuito a Internet. Me centraré en la seguridad de los cablemódems, la tecnología utilizada para gestionarlos, cómo se protegen los datos y cómo los ISPs actualizan los firmwares. Alerta de spoiler: todo es realmente muy malo.

Mientras investigaba sobre el tema, encontré una puerta trasera no revelada anteriormente en los cable módems ARRIS, que afectaba a muchos de sus dispositivos, incluidos los TG862A, TG862G y DG860A. En el momento de escribir este artículo, las búsquedas en Shodan indican que el backdoor afecta a más de 600.000 hosts accesibles externamente y el proveedor no ha declarado si va a solucionarlo todavía.
