A Short range Wireless Communication Standard
for End to End device for share the data between two ends. Like other
Short range Wireless Communication standard, Bluetooth also using an
unlicensed 2.4 GHz baseband communication to Physical Layer. It's
have a protocol stack to perform an end to end application and supports wide range of application in different embedded devices for short range communication . Now it's become an essential communication standard in Smart Mobile and other devices in the market. Before Developing an application for Bluetooth we should have to know about it very well for ease the development .
Bluetooth version
The Bluetooth Special Interest Group (SIG) is the body that oversees the development of Bluetooth standards and the licensing of the Bluetooth technologies and trademarks to manufacturers. The following are some Bluetooth version that we are currently using in different sectors.
- Bluetooth v1.0 and v1.0B
- Bluetooth v1.1
- Bluetooth v1.2
- Bluetooth v2.0 + EDR
- Bluetooth v2.1 + EDR
- Bluetooth v3.0 + HS
- Bluetooth v4.0
- Bluetooth v4.1
Bluetooth Protocol Stack
Baseband + Bluetooth Radio - Physical Layer Operation in Bluetooth or transmission of data from one end to another.
LMP - Link Management Protocol for to Provide a link to the application using the Link channel and also participates the Multiplexing of channel using PSM code in Link Layer.
RFCOMM - RF Virtual COM port for Serial Communication Emulator.
BNEP - Bluetooth Network Encapsulation Protocol is help to provide a network Stack to Bluetooth for doing a SEQPACKET, SOCKSTREAM socket communication to device.
L2CAP - Logical Link Control and Adaptation Protocol provide a logical link connection to the RFCOMM and any other application layer protocol protocol in the Stack.
OBEX -Object Exchange Protocol. Its an application Layer protocol to perform data exchange operation between devices.
SDP - Service Discovery protocol is help to acquire the information of the services run in the Bluetooth device.
Network topology
Bluetooth have one topology named "Scatternet" which help to build a
bluetooth device network, but there have only few implementation is
there in practical scenario. Actually Scatternet is the collection of
small net consist of 7 Bluetooth nodes called as piconet. Piconet
consists of 7 nodes and each node perform a direct link to link
connection between two node. A node is the host all other node in the
network we can call it as "MASTER node" and a node is intended to
connect to the "MASTER node" is called as SLAVE node.
Bluetooth Development Library
BlueZ :-
If you are using Linux you can download from the repo by using the command
#sudo apt-get install bluez
hcidump:-
Promiscuous Sniffer for Bluetooth
#sudo apt-get install bluez-hcidump
Bluecova :-
Bluecova is a Java library for Bluetooth Application Development and it runs over a Java Virtual Machine.
Bluetooth Hacking Tools
BlueScanner
– BlueScanner searches out for Bluetooth-enabled devices. It will try
to extract as much information as possible for each newly discovered
device. Download BlueScan.
BlueSniff – BlueSniff is a GUI-based utility for finding discoverable and hidden Bluetooth-enabled devices. Download BlueSniff.
BTBrowser
– Bluetooth Browser is a J2ME application that can browse and explore
the technical specification of surrounding Bluetooth-enabled devices.
You can browse device information and all
supported profiles and service records of each device. BTBrowser works on phones that supports JSR-82 – the Java Bluetooth specification. Download BTBrowser.
supported profiles and service records of each device. BTBrowser works on phones that supports JSR-82 – the Java Bluetooth specification. Download BTBrowser.
BTCrawler
-BTCrawler is a scanner for Windows Mobile based devices. It scans for
other devices in range and performs service query. It implements the
BlueJacking and BlueSnarfing attacks. Download BTCrawler.
Hacking Bluetooth Devices
BlueBugger
-BlueBugger exploits the BlueBug vulnerability. BlueBug is the name of a
set of Bluetooth security holes found in some Bluetooth-enabled mobile
phones. By exploiting those vulnerabilities, one can gain an
unauthorized access to the phone-book, calls lists and other private
information. Download BlueBugger.
CIHWB
– Can I Hack With Bluetooth (CIHWB) is a Bluetooth security auditing
framework for Windows Mobile 2005. Currently it only support some
Bluetooth exploits and tools like BlueSnarf, BlueJack, and some DoS
attacks. Should work on any PocketPC with the Microsoft Bluetooth stack.
Download CIHWB.
Bluediving
– Bluediving is a Bluetooth penetration testing suite. It implements
attacks like Bluebug, BlueSnarf, BlueSnarf++, BlueSmack, has features
such as Bluetooth address spoofing, an AT and a RFCOMM socket shell and
implements tools like carwhisperer, bss, L2CAP packetgenerator, L2CAP
connection resetter, RFCOMM scanner and green plaque scanning mode. Download Bluediving.
Transient Bluetooth Environment Auditor
– T-BEAR is a security-auditing platform for Bluetooth-enabled devices.
The platform consists of Bluetooth discovery tools, sniffing tools and
various cracking tools. Download T-BEAR.
Bluesnarfer – Bluesnarfer will download the phone-book of any mobile device vulnerable toBluesnarfing.
Bluesnarfing is a serious security flow discovered in several
Bluetooth-enabled mobile phones. If a mobile phone is vulnerable, it is
possible to connect to the phone without alerting the owner, and gain
access to restricted portions of the stored data. Download Bluesnarfer.
BTcrack
– BTCrack is a Bluetooth Pass phrase (PIN) cracking tool. BTCrack aims
to reconstruct the Passkey and the Link key from captured Pairing
exchanges. Download BTcrack.
Blooover II
– Blooover II is a J2ME-based auditing tool. It is intended to serve as
an auditing tool to check whether a mobile phone is vulnerable. Download Blooover II.
BlueTest – BlueTest is a Perl script designed to do data extraction from vulnerable Bluetooth-enabled devices. Download BlueTest.
BTAudit – BTAudit is a set of programs and scripts for auditing Bluetooth-enabled devices. Download BTAuding.
