12,000 | To use Bluetooth wireless technology, a device must be able to interpret certain Bluetooth profiles, which are definitions of possible applications and specify general behaviors that Bluetooth-enabled devices use to communicate with other Bluetooth devices. These profiles include settings to parameterize and to control... | https://en.wikipedia.org/wiki?curid=3742 |
12,001 | Bluetooth and Wi-Fi (Wi-Fi is the brand name for products using IEEE 802.11 standards) have some similar applications: setting up networks, printing, or transferring files. Wi-Fi is intended as a replacement for high-speed cabling for general local area network access in work areas or home. This category of application... | https://en.wikipedia.org/wiki?curid=3742 |
12,002 | Wi-Fi and Bluetooth are to some extent complementary in their applications and usage. Wi-Fi is usually access point-centered, with an asymmetrical client-server connection with all traffic routed through the access point, while Bluetooth is usually symmetrical, between two Bluetooth devices. Bluetooth serves well in si... | https://en.wikipedia.org/wiki?curid=3742 |
12,003 | Bluetooth exists in numerous products such as telephones, speakers, tablets, media players, robotics systems, laptops, and game console equipment as well as some high definition headsets, modems, hearing aids and even watches. Given the variety of devices which use Bluetooth, coupled with the contemporary deprecation o... | https://en.wikipedia.org/wiki?curid=3742 |
12,004 | Bluetooth protocols simplify the discovery and setup of services between devices. Bluetooth devices can advertise all of the services they provide. This makes using services easier, because more of the security, network address and permission configuration can be automated than with many other network types. | https://en.wikipedia.org/wiki?curid=3742 |
12,005 | A personal computer that does not have embedded Bluetooth can use a Bluetooth adapter that enables the PC to communicate with Bluetooth devices. While some desktop computers and most recent laptops come with a built-in Bluetooth radio, others require an external adapter, typically in the form of a small USB "dongle." | https://en.wikipedia.org/wiki?curid=3742 |
12,006 | Unlike its predecessor, IrDA, which requires a separate adapter for each device, Bluetooth lets multiple devices communicate with a computer over a single adapter. | https://en.wikipedia.org/wiki?curid=3742 |
12,007 | For Microsoft platforms, Windows XP Service Pack 2 and SP3 releases work natively with Bluetooth v1.1, v2.0 and v2.0+EDR. Previous versions required users to install their Bluetooth adapter's own drivers, which were not directly supported by Microsoft. Microsoft's own Bluetooth dongles (packaged with their Bluetooth co... | https://en.wikipedia.org/wiki?curid=3742 |
12,008 | The Windows XP and Windows Vista/Windows 7 Bluetooth stacks support the following Bluetooth profiles natively: PAN, SPP, DUN, HID, HCRP. The Windows XP stack can be replaced by a third party stack that supports more profiles or newer Bluetooth versions. The Windows Vista/Windows 7 Bluetooth stack supports vendor-suppli... | https://en.wikipedia.org/wiki?curid=3742 |
12,009 | Linux has two popular Bluetooth stacks, BlueZ and Fluoride. The BlueZ stack is included with most Linux kernels and was originally developed by Qualcomm. Fluoride, earlier known as Bluedroid is included in Android OS and was originally developed by Broadcom. | https://en.wikipedia.org/wiki?curid=3742 |
12,010 | There is also Affix stack, developed by Nokia. It was once popular, but has not been updated since 2005. | https://en.wikipedia.org/wiki?curid=3742 |
12,011 | NetBSD has included Bluetooth since its v4.0 release. Its Bluetooth stack was ported to OpenBSD as well, however OpenBSD later removed it as unmaintained. | https://en.wikipedia.org/wiki?curid=3742 |
12,012 | DragonFly BSD has had NetBSD's Bluetooth implementation since 1.11 (2008). A netgraph-based implementation from FreeBSD has also been available in the tree, possibly disabled until 2014-11-15, and may require more work. | https://en.wikipedia.org/wiki?curid=3742 |
12,013 | The specifications were formalized by the Bluetooth Special Interest Group (SIG) and formally announced on 20 May 1998. Today it has a membership of over 30,000 companies worldwide. It was established by Ericsson, IBM, Intel, Nokia and Toshiba, and later joined by many other companies. | https://en.wikipedia.org/wiki?curid=3742 |
12,014 | All versions of the Bluetooth standards support downward compatibility. That lets the latest standard cover all older versions. | https://en.wikipedia.org/wiki?curid=3742 |
12,015 | This version of the Bluetooth Core Specification was released before 2005. The main difference is the introduction of an Enhanced Data Rate (EDR) for faster data transfer. The bit rate of EDR is 3Mbit/s, although the maximum data transfer rate (allowing for inter-packet time and acknowledgements) is 2.1Mbit/s. EDR uses... | https://en.wikipedia.org/wiki?curid=3742 |
12,016 | The specification is published as "Bluetooth v2.0 + EDR", which implies that EDR is an optional feature. Aside from EDR, the v2.0 specification contains other minor improvements, and products may claim compliance to "Bluetooth v2.0" without supporting the higher data rate. At least one commercial device states "Bluetoo... | https://en.wikipedia.org/wiki?curid=3742 |
12,017 | The headline feature of v2.1 is secure simple pairing (SSP): this improves the pairing experience for Bluetooth devices, while increasing the use and strength of security. | https://en.wikipedia.org/wiki?curid=3742 |
12,018 | Version 2.1 allows various other improvements, including "extended inquiry response" (EIR), which provides more information during the inquiry procedure to allow better filtering of devices before connection; and sniff subrating, which reduces the power consumption in low-power mode. | https://en.wikipedia.org/wiki?curid=3742 |
12,019 | Version 3.0 + HS of the Bluetooth Core Specification was adopted by the Bluetooth SIG on 21 April 2009. Bluetooth v3.0 + HS provides theoretical data transfer speeds of up to 24 Mbit/s, though not over the Bluetooth link itself. Instead, the Bluetooth link is used for negotiation and establishment, and the high data ra... | https://en.wikipedia.org/wiki?curid=3742 |
12,020 | The main new feature is AMP (Alternative MAC/PHY), the addition of 802.11 as a high-speed transport. The high-speed part of the specification is not mandatory, and hence only devices that display the "+HS" logo actually support Bluetooth over 802.11 high-speed data transfer. A Bluetooth v3.0 device without the "+HS" su... | https://en.wikipedia.org/wiki?curid=3742 |
12,021 | The high-speed (AMP) feature of Bluetooth v3.0 was originally intended for UWB, but the WiMedia Alliance, the body responsible for the flavor of UWB intended for Bluetooth, announced in March 2009 that it was disbanding, and ultimately UWB was omitted from the Core v3.0 specification. | https://en.wikipedia.org/wiki?curid=3742 |
12,022 | On 16 March 2009, the WiMedia Alliance announced it was entering into technology transfer agreements for the WiMedia Ultra-wideband (UWB) specifications. WiMedia has transferred all current and future specifications, including work on future high-speed and power-optimized implementations, to the Bluetooth Special Inter... | https://en.wikipedia.org/wiki?curid=3742 |
12,023 | In October 2009, the Bluetooth Special Interest Group suspended development of UWB as part of the alternative MAC/PHY, Bluetooth v3.0 + HS solution. A small, but significant, number of former WiMedia members had not and would not sign up to the necessary agreements for the IP transfer. As of 2009, the Bluetooth SIG was... | https://en.wikipedia.org/wiki?curid=3742 |
12,024 | The Bluetooth SIG completed the Bluetooth Core Specification version 4.0 (called Bluetooth Smart) and has been adopted . It includes "Classic Bluetooth", "Bluetooth high speed" and "Bluetooth Low Energy" (BLE) protocols. Bluetooth high speed is based on Wi-Fi, and Classic Bluetooth consists of legacy Bluetooth protocol... | https://en.wikipedia.org/wiki?curid=3742 |
12,025 | Bluetooth Low Energy, previously known as Wibree, is a subset of Bluetooth v4.0 with an entirely new protocol stack for rapid build-up of simple links. As an alternative to the Bluetooth standard protocols that were introduced in Bluetooth v1.0 to v3.0, it is aimed at very low power applications powered by a coin cell.... | https://en.wikipedia.org/wiki?curid=3742 |
12,026 | Compared to "Classic Bluetooth", Bluetooth Low Energy is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range. In terms of lengthening the battery life of Bluetooth devices, represents a significant progression. | https://en.wikipedia.org/wiki?curid=3742 |
12,027 | Cost-reduced single-mode chips, which enable highly integrated and compact devices, feature a lightweight Link Layer providing ultra-low power idle mode operation, simple device discovery, and reliable point-to-multipoint data transfer with advanced power-save and secure encrypted connections at the lowest possible cos... | https://en.wikipedia.org/wiki?curid=3742 |
12,028 | General improvements in version 4.0 include the changes necessary to facilitate BLE modes, as well the Generic Attribute Profile (GATT) and Security Manager (SM) services with AES Encryption. | https://en.wikipedia.org/wiki?curid=3742 |
12,029 | Core Specification Addendum 2 was unveiled in December 2011; it contains improvements to the audio Host Controller Interface and to the High Speed (802.11) Protocol Adaptation Layer. | https://en.wikipedia.org/wiki?curid=3742 |
12,030 | The Bluetooth SIG announced formal adoption of the Bluetooth v4.1 specification on 4 December 2013. This specification is an incremental software update to Bluetooth Specification v4.0, and not a hardware update. The update incorporates Bluetooth Core Specification Addenda (CSA 1, 2, 3 & 4) and adds new features that i... | https://en.wikipedia.org/wiki?curid=3742 |
12,031 | Notice that some features were already available in a Core Specification Addendum (CSA) before the release of v4.1. | https://en.wikipedia.org/wiki?curid=3742 |
12,032 | Older Bluetooth hardware may receive 4.2 features such as Data Packet Length Extension and improved privacy via firmware updates. | https://en.wikipedia.org/wiki?curid=3742 |
12,033 | The Bluetooth SIG released Bluetooth 5 on 6 December 2016. Its new features are mainly focused on new Internet of Things technology. Sony was the first to announce Bluetooth 5.0 support with its Xperia XZ Premium in Feb 2017 during the Mobile World Congress 2017. The Samsung Galaxy S8 launched with Bluetooth 5 support ... | https://en.wikipedia.org/wiki?curid=3742 |
12,034 | Bluetooth 5 provides, for BLE, options that can double the speed (2Mbit/s burst) at the expense of range, or provide up to four times the range at the expense of data rate. The increase in transmissions could be important for Internet of Things devices, where many nodes connect throughout a whole house. Bluetooth 5 inc... | https://en.wikipedia.org/wiki?curid=3742 |
12,035 | On 31 December 2019, the Bluetooth SIG published the Bluetooth Core Specification Version 5.2. The new specification adds new features: | https://en.wikipedia.org/wiki?curid=3742 |
12,036 | The Bluetooth SIG published the Bluetooth Core Specification Version 5.3 on 13 July 2021. The feature enhancements of Bluetooth 5.3 are: | https://en.wikipedia.org/wiki?curid=3742 |
12,037 | Seeking to extend the compatibility of Bluetooth devices, the devices that adhere to the standard use an interface called HCI (Host Controller Interface) between the host device (e.g. laptop, phone) and the Bluetooth device (e.g. Bluetooth wireless headset). | https://en.wikipedia.org/wiki?curid=3742 |
12,038 | High-level protocols such as the SDP (Protocol used to find other Bluetooth devices within the communication range, also responsible for detecting the function of devices in range), RFCOMM (Protocol used to emulate serial port connections) and TCS (Telephony control protocol) interact with the baseband controller throu... | https://en.wikipedia.org/wiki?curid=3742 |
12,039 | The hardware that makes up the Bluetooth device is made up of, logically, two parts; which may or may not be physically separate. A radio device, responsible for modulating and transmitting the signal; and a digital controller. The digital controller is likely a CPU, one of whose functions is to run a Link Controller; ... | https://en.wikipedia.org/wiki?curid=3742 |
12,040 | A Bluetooth device is a short-range wireless device. Bluetooth devices are fabricated on RF CMOS integrated circuit (RF circuit) chips. | https://en.wikipedia.org/wiki?curid=3742 |
12,041 | Bluetooth is defined as a layer protocol architecture consisting of core protocols, cable replacement protocols, telephony control protocols, and adopted protocols. Mandatory protocols for all Bluetooth stacks are LMP, L2CAP and SDP. In addition, devices that communicate with Bluetooth almost universally can use these ... | https://en.wikipedia.org/wiki?curid=3742 |
12,042 | The Link Manager (LM) is the system that manages establishing the connection between devices. It is responsible for the establishment, authentication and configuration of the link. The Link Manager locates other managers and communicates with them via the management protocol of the LMP link. To perform its function as ... | https://en.wikipedia.org/wiki?curid=3742 |
12,043 | The Link Manager Protocol basically consists of several PDUs (Protocol Data Units) that are sent from one device to another. The following is a list of supported services: | https://en.wikipedia.org/wiki?curid=3742 |
12,044 | The Host Controller Interface provides a command interface for the controller and for the link manager, which allows access to the hardware status and control registers. | https://en.wikipedia.org/wiki?curid=3742 |
12,045 | This interface provides an access layer for all Bluetooth devices. The HCI layer of the machine exchanges commands and data with the HCI firmware present in the Bluetooth device. One of the most important HCI tasks that must be performed is the automatic discovery of other Bluetooth devices that are within the coverage... | https://en.wikipedia.org/wiki?curid=3742 |
12,046 | The "Logical Link Control and Adaptation Protocol" (L2CAP) is used to multiplex multiple logical connections between two devices using different higher level protocols. | https://en.wikipedia.org/wiki?curid=3742 |
12,047 | In "Basic" mode, L2CAP provides packets with a payload configurable up to 64 kB, with 672 bytes as the default MTU, and 48 bytes as the minimum mandatory supported MTU. | https://en.wikipedia.org/wiki?curid=3742 |
12,048 | In "Retransmission and Flow Control" modes, L2CAP can be configured either for isochronous data or reliable data per channel by performing retransmissions and CRC checks. | https://en.wikipedia.org/wiki?curid=3742 |
12,049 | Bluetooth Core Specification Addendum 1 adds two additional L2CAP modes to the core specification. These modes effectively deprecate original Retransmission and Flow Control modes: | https://en.wikipedia.org/wiki?curid=3742 |
12,050 | Reliability in any of these modes is optionally and/or additionally guaranteed by the lower layer Bluetooth BDR/EDR air interface by configuring the number of retransmissions and flush timeout (time after which the radio flushes packets). In-order sequencing is guaranteed by the lower layer. | https://en.wikipedia.org/wiki?curid=3742 |
12,051 | The "Service Discovery Protocol" (SDP) allows a device to discover services offered by other devices, and their associated parameters. For example, when you use a mobile phone with a Bluetooth headset, the phone uses SDP to determine which Bluetooth profiles the headset can use (Headset Profile, Hands Free Profile (HFP... | https://en.wikipedia.org/wiki?curid=3742 |
12,052 | "Radio Frequency Communications" (RFCOMM) is a cable replacement protocol used for generating a virtual serial data stream. RFCOMM provides for binary data transport and emulates EIA-232 (formerly RS-232) control signals over the Bluetooth baseband layer, i.e., it is a serial port emulation. | https://en.wikipedia.org/wiki?curid=3742 |
12,053 | RFCOMM provides a simple, reliable, data stream to the user, similar to TCP. It is used directly by many telephony related profiles as a carrier for AT commands, as well as being a transport layer for OBEX over Bluetooth. | https://en.wikipedia.org/wiki?curid=3742 |
12,054 | Many Bluetooth applications use RFCOMM because of its widespread support and publicly available API on most operating systems. Additionally, applications that used a serial port to communicate can be quickly ported to use RFCOMM. | https://en.wikipedia.org/wiki?curid=3742 |
12,055 | The "Bluetooth Network Encapsulation Protocol" (BNEP) is used for transferring another protocol stack's data via an L2CAP channel. | https://en.wikipedia.org/wiki?curid=3742 |
12,056 | The "Audio/Video Control Transport Protocol" (AVCTP) is used by the remote control profile to transfer AV/C commands over an L2CAP channel. The music control buttons on a stereo headset use this protocol to control the music player. | https://en.wikipedia.org/wiki?curid=3742 |
12,057 | The "Audio/Video Distribution Transport Protocol" (AVDTP) is used by the advanced audio distribution (A2DP) profile to stream music to stereo headsets over an L2CAP channel intended for video distribution profile in the Bluetooth transmission. | https://en.wikipedia.org/wiki?curid=3742 |
12,058 | The "Telephony Control Protocol– Binary" (TCS BIN) is the bit-oriented protocol that defines the call control signaling for the establishment of voice and data calls between Bluetooth devices. Additionally, "TCS BIN defines mobility management procedures for handling groups of Bluetooth TCS devices." | https://en.wikipedia.org/wiki?curid=3742 |
12,059 | TCS-BIN is only used by the cordless telephony profile, which failed to attract implementers. As such it is only of historical interest. | https://en.wikipedia.org/wiki?curid=3742 |
12,060 | Adopted protocols are defined by other standards-making organizations and incorporated into Bluetooth's protocol stack, allowing Bluetooth to code protocols only when necessary. The adopted protocols include: | https://en.wikipedia.org/wiki?curid=3742 |
12,061 | Depending on packet type, individual packets may be protected by error correction, either 1/3 rate forward error correction (FEC) or 2/3 rate. In addition, packets with CRC will be retransmitted until acknowledged by automatic repeat request (ARQ). | https://en.wikipedia.org/wiki?curid=3742 |
12,062 | Any device may perform an inquiry to find other devices to connect to, and any device can be configured to respond to such inquiries. However, if the device trying to connect knows the address of the device, it always responds to direct connection requests and transmits the information shown in the list above if reques... | https://en.wikipedia.org/wiki?curid=3742 |
12,063 | Every device has a unique 48-bit address. However, these addresses are generally not shown in inquiries. Instead, friendly Bluetooth names are used, which can be set by the user. This name appears when another user scans for devices and in lists of paired devices. | https://en.wikipedia.org/wiki?curid=3742 |
12,064 | Most cellular phones have the Bluetooth name set to the manufacturer and model of the phone by default. Most cellular phones and laptops show only the Bluetooth names and special programs are required to get additional information about remote devices. This can be confusing as, for example, there could be several cellu... | https://en.wikipedia.org/wiki?curid=3742 |
12,065 | Many services offered over Bluetooth can expose private data or let a connecting party control the Bluetooth device. Security reasons make it necessary to recognize specific devices, and thus enable control over which devices can connect to a given Bluetooth device. At the same time, it is useful for Bluetooth devices ... | https://en.wikipedia.org/wiki?curid=3742 |
12,066 | To resolve this conflict, Bluetooth uses a process called "bonding", and a bond is generated through a process called "pairing". The pairing process is triggered either by a specific request from a user to generate a bond (for example, the user explicitly requests to "Add a Bluetooth device"), or it is triggered automa... | https://en.wikipedia.org/wiki?curid=3742 |
12,067 | Pairing often involves some level of user interaction. This user interaction confirms the identity of the devices. When pairing completes, a bond forms between the two devices, enabling those two devices to connect in the future without repeating the pairing process to confirm device identities. When desired, the user ... | https://en.wikipedia.org/wiki?curid=3742 |
12,068 | During pairing, the two devices establish a relationship by creating a shared secret known as a "link key". If both devices store the same link key, they are said to be "paired" or "bonded". A device that wants to communicate only with a bonded device can cryptographically authenticate the identity of the other device,... | https://en.wikipedia.org/wiki?curid=3742 |
12,069 | Bluetooth services generally require either encryption or authentication and as such require pairing before they let a remote device connect. Some services, such as the Object Push Profile, elect not to explicitly require authentication or encryption so that pairing does not interfere with the user experience associate... | https://en.wikipedia.org/wiki?curid=3742 |
12,070 | Pairing mechanisms changed significantly with the introduction of Secure Simple Pairing in Bluetooth v2.1. The following summarizes the pairing mechanisms: | https://en.wikipedia.org/wiki?curid=3742 |
12,071 | Prior to Bluetooth v2.1, encryption is not required and can be turned off at any time. Moreover, the encryption key is only good for approximately 23.5 hours; using a single encryption key longer than this time allows simple XOR attacks to retrieve the encryption key. | https://en.wikipedia.org/wiki?curid=3742 |
12,072 | Link keys may be stored on the device file system, not on the Bluetooth chip itself. Many Bluetooth chip manufacturers let link keys be stored on the device—however, if the device is removable, this means that the link key moves with the device. | https://en.wikipedia.org/wiki?curid=3742 |
12,073 | Bluetooth implements confidentiality, authentication and key derivation with custom algorithms based on the SAFER+ block cipher. Bluetooth key generation is generally based on a Bluetooth PIN, which must be entered into both devices. This procedure might be modified if one of the devices has a fixed PIN (e.g., for head... | https://en.wikipedia.org/wiki?curid=3742 |
12,074 | The E0 stream cipher is used for encrypting packets, granting confidentiality, and is based on a shared cryptographic secret, namely a previously generated link key or master key. Those keys, used for subsequent encryption of data sent via the air interface, rely on the Bluetooth PIN, which has been entered into one or... | https://en.wikipedia.org/wiki?curid=3742 |
12,075 | In September 2008, the National Institute of Standards and Technology (NIST) published a Guide to Bluetooth Security as a reference for organizations. It describes Bluetooth security capabilities and how to secure Bluetooth technologies effectively. While Bluetooth has its benefits, it is susceptible to denial-of-servi... | https://en.wikipedia.org/wiki?curid=3742 |
12,076 | Bluetooth v2.1 – finalized in 2007 with consumer devices first appearing in 2009 – makes significant changes to Bluetooth's security, including pairing. See the pairing mechanisms section for more about these changes. | https://en.wikipedia.org/wiki?curid=3742 |
12,077 | Bluejacking is the sending of either a picture or a message from one user to an unsuspecting user through Bluetooth wireless technology. Common applications include short messages, e.g., "You've just been bluejacked!" Bluejacking does not involve the removal or alteration of any data from the device. Bluejacking can al... | https://en.wikipedia.org/wiki?curid=3742 |
12,078 | Some form of DoS is also possible, even in modern devices, by sending unsolicited pairing requests in rapid succession; this becomes disruptive because most systems display a full screen notification for every connection request, interrupting every other activity, especially on less powerful devices. | https://en.wikipedia.org/wiki?curid=3742 |
12,079 | In 2001, Jakobsson and Wetzel from Bell Laboratories discovered flaws in the Bluetooth pairing protocol and also pointed to vulnerabilities in the encryption scheme. In 2003, Ben and Adam Laurie from A.L. Digital Ltd. discovered that serious flaws in some poor implementations of Bluetooth security may lead to disclosur... | https://en.wikipedia.org/wiki?curid=3742 |
12,080 | The virus was first described by Kaspersky Lab and requires users to confirm the installation of unknown software before it can propagate. The virus was written as a proof-of-concept by a group of virus writers known as "29A" and sent to anti-virus groups. Thus, it should be regarded as a potential (but not real) secur... | https://en.wikipedia.org/wiki?curid=3742 |
12,081 | This poses a potential security threat because it enables attackers to access vulnerable Bluetooth devices from a distance beyond expectation. The attacker must also be able to receive information from the victim to set up a connection. No attack can be made against a Bluetooth device unless the attacker knows its Blue... | https://en.wikipedia.org/wiki?curid=3742 |
12,082 | In January 2005, a mobile malware worm known as Lasco surfaced. The worm began targeting mobile phones using Symbian OS (Series 60 platform) using Bluetooth enabled devices to replicate itself and spread to other devices. The worm is self-installing and begins once the mobile user approves the transfer of the file (Vel... | https://en.wikipedia.org/wiki?curid=3742 |
12,083 | In April 2005, Cambridge University security researchers published results of their actual implementation of passive attacks against the PIN-based pairing between commercial Bluetooth devices. They confirmed that attacks are practicably fast, and the Bluetooth symmetric key establishment method is vulnerable. To rectif... | https://en.wikipedia.org/wiki?curid=3742 |
12,084 | In June 2005, Yaniv Shaked and Avishai Wool published a paper describing both passive and active methods for obtaining the PIN for a Bluetooth link. The passive attack allows a suitably equipped attacker to eavesdrop on communications and spoof if the attacker was present at the time of initial pairing. The active meth... | https://en.wikipedia.org/wiki?curid=3742 |
12,085 | In August 2005, police in Cambridgeshire, England, issued warnings about thieves using Bluetooth enabled phones to track other devices left in cars. Police are advising users to ensure that any mobile networking connections are de-activated if laptops and other devices are left in this way. | https://en.wikipedia.org/wiki?curid=3742 |
12,086 | In April 2006, researchers from Secure Network and F-Secure published a report that warns of the large number of devices left in a visible state, and issued statistics on the spread of various Bluetooth services and the ease of spread of an eventual Bluetooth worm. | https://en.wikipedia.org/wiki?curid=3742 |
12,087 | In October 2006, at the Luxemburgish Hack.lu Security Conference, Kevin Finistere and Thierry Zoller demonstrated and released a remote root shell via Bluetooth on Mac OS X v10.3.9 and v10.4. They also demonstrated the first Bluetooth PIN and Linkkeys cracker, which is based on the research of Wool and Shaked. | https://en.wikipedia.org/wiki?curid=3742 |
12,088 | In April 2017, security researchers at Armis discovered multiple exploits in the Bluetooth software in various platforms, including Microsoft Windows, Linux, Apple iOS, and Google Android. These vulnerabilities are collectively called "BlueBorne". The exploits allow an attacker to connect to devices or systems without ... | https://en.wikipedia.org/wiki?curid=3742 |
12,089 | In July 2018, Lior Neumann and Eli Biham, researchers at the Technion – Israel Institute of Technology identified a security vulnerability in the latest Bluetooth pairing procedures: Secure Simple Pairing and LE Secure Connections. | https://en.wikipedia.org/wiki?curid=3742 |
12,090 | Also, in October 2018, Karim Lounis, a network security researcher at Queen's University, identified a security vulnerability, called CDV (Connection Dumping Vulnerability), on various Bluetooth devices that allows an attacker to tear down an existing Bluetooth connection and cause the deauthentication and disconnectio... | https://en.wikipedia.org/wiki?curid=3742 |
12,091 | In August 2019, security researchers at the Singapore University of Technology and Design, Helmholtz Center for Information Security, and University of Oxford discovered a vulnerability, called KNOB (Key Negotiation Of Bluetooth) in the key negotiation that would "brute force the negotiated encryption keys, decrypt the... | https://en.wikipedia.org/wiki?curid=3742 |
12,092 | Bluetooth uses the radio frequency spectrum in the 2.402GHz to 2.480GHz range, which is non-ionizing radiation, of similar bandwidth to that used by wireless and mobile phones.
