Forget Wi-Fi. Meet the new Li-Fi Internet | Harald Haas
TED
▻https://www.youtube.com/watch?v=iHWIZsIBj3QLi-Fi
▻https://en.wikipedia.org/wiki/Li-FiLi-Fi is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi. The term was coined by Harald Haas and is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or cellular networks), or even a replacement in contexts of data broadcasting.
It is wire and UV visible-light communication or infrared and near-ultraviolet instead of radio-frequency spectrum, part of optical wireless communications technology, which carries much more information and has been proposed as a solution to the RF-bandwidth limitations.

“German researchers have discovered security flaws that could let hackers, spies and criminals listen to private phone calls and intercept text messages on a potentially massive scale – even when cellular networks are using the most advanced encryption now available.
The flaws, to be reported at a hacker conference in Hamburg this month, are the latest evidence of widespread insecurity on SS7, the global network that allows the world’s cellular carriers to route calls, texts and other services to each other.”

SS7 is indeed awfully broken but, unlike what happens on the Internet (where everyone knows about the weaknesses of BGP and DNS and work on it), the telco companies were, until now, successful in hiding the problem under the rug.

Symantec Discovers ’Regin’ Spy Code Lurking on Computer Networks
▻http://bits.blogs.nytimes.com/2014/11/24/symantec-discovers-spy-code-lurking-on-computer-networksThe security company indicated that a powerful program that could only have been created by a “nation state” has been finding its way into computer systems for six years.

“In the world of malware threats, only a few rare examples can truly be considered groundbreaking and almost peerless,” Symantec wrote. “What we have seen in Regin is just such a class of malware.”

But perhaps the most significant aspect of Regin is its ability to target GSM base stations of cellular networks. The malicious arsenal includes a payload that Kaspersky says was used in 2008 to steal the usernames and passwords of system administrators of a telecom somewhere in the Middle East.

For sale : Systems that can secretly track where cellphone users go around the globe - The Washington Post
▻http://www.washingtonpost.com/business/technology/for-sale-systems-that-can-secretly-track-where-cellphone-users-go-around-the-globe/2014/08/24/f0700e8a-f003-11e3-bf76-447a5df6411f_story.htmlMakers of surveillance systems are offering governments across the world the ability to track the movements of almost anybody who carries a cellphone, whether they are blocks away or on another continent.
The technology works by exploiting an essential fact of all cellular networks: They must keep detailed, up-to-the-minute records on the locations of their customers to deliver calls and other services to them. Surveillance systems are secretly collecting these records to map people’s travels over days, weeks or longer, according to company marketing documents and experts in surveillance technology.
The world’s most powerful intelligence services, such as the National Security Agency and Britain’s GCHQ, long have used cellphone data to track targets around the globe. But experts say these new systems allow less technically advanced governments to track people in any nation — including the United States — with relative ease and precision.
Users of such technology type a phone number into a computer portal, which then collects information from the location databases maintained by cellular carriers, company documents show. In this way, the surveillance system learns which cell tower a target is currently using, revealing his or her location to within a few blocks in an urban area or a few miles in a rural one.
It is unclear which governments have acquired these tracking systems, but one industry official, speaking on the condition of anonymity to share sensitive trade information, said that dozens of countries have bought or leased such technology in recent years. This rapid spread underscores how the burgeoning, multibillion-dollar surveillance industry makes advanced spying technology available worldwide.
La #surveillance à la portée de tous (enfin, tous les gouvernements, même les plus pauvres).

qaul.net – قول
▻http://qaul.net/text_en.htmlqaul.net implements a redundant, open communication principle, in which wireless-enabled computers and mobile devices can directly form a spontaneous network. Text messaging, file sharing and voice calls are possible independent of internet and cellular networks. Qaul.net can spread like a virus, and an Open Source Community can modify it freely.
In a time of communication blackouts in places like Egypt, Burma, and Tibet, and given the large power outages often caused by natural disasters, qaul.net has taken on the challenge of critically examining existing communication pathways while simultaneously exploring new horizons.
