I have already talked in the past about how unsecure bluetooth can be, if not secured correctly, with bluesnarfing, a lot of your information could be in danger. When I first talk about this, the number of bluetooth devices were still very small, and it didn't represent a real danger. Meanwhile, the adoption of bluetooth has been growing quite fast amd almost all phones have now incorporated the bluetooth turn on by default, and everyone, not just the the businessmens, have discovered the joys of wireless world, with bluetooth headsets.
What is happening? Well that not only your contacts are in danger anymore, but aswell your voice conversations, as it seems that it is rather easy to actually snoop in voice communication over bluetooth, and even change it.
Take a look at the video that I am attaching to this post, and you actually be surprised, not only the voice communication can be spied and modified, it can be done from a couple of meters more than the theorical ten meters range of the bluetooth.
Does this represent a problem? Well it depends on the subject of your conversations, but from what you can see in the streets lately from people with their phones, if that privacy doesn´t seems to matter any more
One the things that have stroke me lately in Wireless networks, is the level of security that we have reached in the home wireless networks. From having almost no wireless networks in my neighborhood, I have gone to having a couple of them totally open, and suddenly a lot of them totally closed. I don´t have tried to break any key, although I was tented to, in order to understand was strong was the security implemented, until I heard some of my neighbors, complaining to his wife:" Darling, I have lost the WPA key to our networks, so I am not able to configure our new computer to access ...". This dialog can have only two possible sources: - People are receiving the wireless router already configured to be secure, and the keys are being written in the information provided with the router. - People are aware of the potential problems caused by the wireless and they are using the tougher passwords they can remember, in order to protect their connections.
Neither way, the problem is that when you loose the keys you are in a really big problem if you don´t know how to proceed afterwards. The couple in this story was lucky, and I advise them to just reset the configuration to the factory and to reconfigure everything with the DVDs provided by the telecom operator. But, the question stays in the air, how many people are blocked to perform further configurations changes to their network, due to have lost the keys?
Durante mis amenas lecturas de noticias relacionadas con el WIFI, he encontrado un articulo ( DiarioTI) muy interesante sobre el robo de identidades en WIFI. Mismo que no sea expresamente relacionado con el WIFI, pero si mas bien relacionado sobre la transparencia de un WIFI mal configurado, es interesante la noticias por dos temas distintos:
Um link interesante para todos los que puedan tener problemas con el vecindario enganchado de forma anónima y/o pirata a su conexión WIFI.
Según una noticia de El Periodista Digital (Español) habria una script que se puede bajar del siguiente Link que permite tornar toda la información de forma borrosa y distorcionada.
Un policia lo viu y le arrestou por no consumir nada . Situación ridicula y peligrosa? Sobretodo para el pobre hombre que sin saber cuasi se lleva mas de cinco años de carcel...
