Protocol Bluetooth wireless for a few years became widely popular. His support - standard attribute of a wide range of mobile office and home purposes. The volume of worldwide sales of Bluetooth-enabled devices is estimated at $ 2 million per week and gradually increasing. Conscientious users will appreciate the potential of new technology - but not only them. It is known that the Bluetooth-devices have a very small radius of action - a few tens of meters, or about 10 m. This would seem to reliably protects them from unauthorized remote access - hacking and manipulation. But not so long ago, it turned out that Bluetooth can be hacked on a huge distance. It amounts to many hundreds of meters, and it does not require any unique equipment. This led to the emergence of new classes - bluesnarfing, which quickly becomes "competitive sports, features, and themselves hackers call themselves bluesniper (" blue sniper "). Revels blue snipers " New sport and its associated problems and risks received much attention at a security conference Defcon, held in Las Vegas. The protocol Bluetooth has a large arsenal of capabilities to protect against unauthorized access. But experience shows that users often ignore recommendations of experts, which leads to serious "holes" in the safe use of specific devices and the real threat of losing confidential information transmitted between Bluetooth-module. However, since the emergence of Bluetooth in these modules found many "holes". Thus, relatively recently emerged that there are three main classes of remote "attacks" on devices that support Bluetooth. They received the following names - bluesnarfing, bluetracking and bluebugging. Bluesnarfing involves an attack on the Bluetooth-device (typically a mobile phone) in order to extract information from it - for example, download the address book. Bluetracking - a movement tracking device, and along with it - and its owner, by a unique address similar to MAC-address computer network cards. Bluebugging is to send commands to a Bluetooth-device. For example, you can make cell phone Bluetooth-secretly call myself an attacker, turning it into the device, bugging her about anything unsuspecting owner. At present, more and more often to refer to these three types of attacks used an umbrella term bluesnarfing. And this kind of activity has rapidly gained the features of a new type of "sport". Its members call themselves and their equipment English terms, beginning with blue-, for example, bluesniper ( "blue sniper"). Bluesnarfing only a part of life, and clearly describe it very difficult. The definition of online fans of this high-tech "games" and, obviously, does not fully reflect the content of such courses, says: "Blyusnarfing is a kind of exercises, which aim to use the vulnerability in the implementation of Bluetooth in mobile phones to steal data from them, hacking phone devices, make calls with them or send text messages without the permission of their owners and without their knowledge. " The main threat is that hacking Bluetooth-enabled devices become possible with the distance, far exceeding the manufacturer's range of devices (remember that this is the first tens of meters). With the emergence of Bluetooth in mobile devices before hackers have opened breathtaking perspective. A sad chronology Chronology of Records in the "remote hacking" is as follows. Security Specialist UK-based AL Digital Adam Laurie (Adam Laurie) found that a new specific vulnerability in the Bluetooth protocol November 2003 As early as April 2004, the distance from which it was possible to carry out hacking the phone, was 80 meters. In late July 2004 a group of enthusiasts from California was able to connect to the normal Bluetooth-phone at a distance of 1 km. We used the flat antenna gain 19 dB. However, August 6, 2004 there were reports of a new "World Record" in the field of hacking Bluetooth. Austrian specialist and expert in the field of Bluetooth Herfurth Martin (Martin Herfurt) and colleagues conducted on August 3 bluesnarfing cell phone from a distance of more than one mile (1.08 mile - about 1,74 km). It also used directional antenna gain 19 dB. Far bluesnaffering: the world's "records" Frightening vulnerability of Bluetooth has been given considerable attention to security conferences - Black Hat and DefCon, which took place in July 2004 in Las Vegas. Here, in particular, was presented to the system bluesniper ( "Blue Sniper"), designed to remotely connect to Bluetooth-devices. Device bluesniper a rifle with telescopic sight, where the antenna is installed instead of the barrel type wave channel, calculated at the operating frequency of Bluetooth. The antenna is connected to a laptop or PDA. Its creators also showed off software designed to scan a Bluetooth-enabled devices. Power "blue" sniper rifle allows you to find and recognize Bluetooth-devices, even behind walls. Last new opportunities for burglary home and office Bluetooth-enabled devices, and makes new, more serious demands to the corporate Bluetooth-security.
