Security on mobile devices: Bluetooth

Over the last few sales jobs months we are witnessing the emergence on the Internet, increasingly frequently, including War Nibbling terms, BlueSnarf, BlueJack or BlueBug, all referring to devices that incorporate Bluetooth technology, some of them are present in news mention (sometimes a little too alarmist tone) of new threats which affect mainly the latest models of mobile phones. Throughout this article, is to introduce the reader to these new threats, unknown to most users of mobile telephony, while introducing tools that facilitate the verification and / or operation of these threats. Bluetooth Technology While that still does not enjoy wide acceptance by users, perhaps even advocate the use of 802.11 wireless networks, Bluetooth technology is being adopted by a number of hardware manufacturers, winning each time a more popular. Designed with the idea of replacing the cables connecting the various electronic devices, fixed and / or portable with minimal intervention by the user. As to highlight key features, include its low complexity and a low power needs, which together with its low cost makes it ideal for a wide variety of artifacts. Bluetooth uses radio frequency link short-range, operating as it recruitment happens with WLAN devices in the 2.4 Ghz band.While most devices have limited its scope at distances less than 10 meters, the latest models that are emerging in the market have a maximum range of 100 meters (Class 1), being also the most power consuming. Perhaps for this reason it is becoming increasingly common inclusion recruiting of connection between the capabilities of the latest devices that are coming to market. Among those on one side are the latest models of mobile phones, PDA type agendas, laptops, access points, peripherals such as mice, keyboards and printers and on the other hand recruiter a whole string of multiple accessories for either telephony or for use with multimedia devices such as headsets or hands-free. It seems appropriate to consider the possibility that such a list of items to be affected soon by new and exotic unauthorized manipulations, as the temptation to undertake research in this direction by the underground community is giving a glimpse with the recent emergence viruses and Trojans recruiting for certain mobile phones. Done this seen by many more as a myth or a means used by the antivirus software development companies that as job search a real threat. Both Tyco and MCI have worked with Founded, G100, CEO Academy and Chairman Academy; Unauthorized uses of devices Armed with a PDA, a next-generation mobile phone or a laptop computer and appropriate software, you can perform many actions by linking two Bluetooth devices, even if that one is in "stealth" mode .A clear example is the misuse of the telephone terminal of any person elected as a victim, to establish a connection without your consent to data transmission services, or perhaps to make phone calls to premium rate numbers with the simple aim of benefiting the owner service. In other cases, it is likely that the attackers simply want a little fun sending messages anonymously to other people, or made passing the line of what may be ethically acceptable, they can get the phone number of his victim to upset subsequently or caused any injury. One way to obtain the phone number of the attack, is to harness the capabilities of Bluetooth connectivity terminal and send an SMS message to another device.
