To do this, a nearby hacker forces your device to use weaker encryption when it connects, making it easier for him to crack it.
Sound complicated? It kind of is. For the KNOB exploit to work, the hacker has to be physically close to you when you connect your two Bluetooth devices.
And he only has a short window of time to intercept the handshake and force a different encryption method. Consider also the vulnerability uncovered by researchers at Boston University.
Connected Bluetooth devices, like earbuds and speakers, broadcast their identity in a surprisingly detectable way.
Both of these vulnerabilities popped up in the last month, and you only have to scroll back a year to find another. Even worse, she can also inject malicious messages on the device.
And we could go on. With Just Works, any device can instantly connect, issue commands, and read data without any other authentication.
Moffitt describes a cloud-connected smart toy he once evaluated that could play audio messages stored in the cloud. Unfortunately, you could also connect to the toy via Bluetooth.
It used no authentication whatsoever, so a malicious actor could stand outside and record anything to it. Moffitt sees the price-sensitive device market as a problem.
There is often zero security vetting going into the design of these products. The attractive nuisance doctrine is an aspect of tort law.
Some Bluetooth features are like an attractive nuisance that put your device and data at risk, and no hacking is required.
For example, many phones have a smart lock feature. So, if you wear Bluetooth headphones, your phone remains unlocked as long as you have them on.
While this is convenient, it makes you vulnerable to hacking. It locks your computer when your phone goes out of Bluetooth range.
It is important to mention that most current smartphones accept AT commands via Bluetooth. The AT interface is an entry point for accessing the baseband processor, so any anomalous behavior when processing any AT command could cause unauthorized access to sensitive information stored on the smartphone, alterations in the operation of the cellular network, among other flaws.
Some research previously conducted regarding failures in the AT interface focuses only on finding invalid or malicious AT commands for manufacturers to blacklist them and prevent possible abuse behavior; however, vulnerability testing specialists consider the scope of this approach to be really small, because although there are AT commands used by the entire mobile communications industry, every single smartphone manufacturer often include its own sets of AT commands to perform various tasks.
In other words, this approach is too specific. Instead, experts propose to design a method of analyzing processes related to the execution of any AT command to detect any possible anomalous activity that may become an exploitable vulnerability.
These are code snippets used to control some tasks related to cellular network usage. A basic set of commands was established as a standard in the mobile communications industry; on the other hand, smartphone manufacturers include their own AT commands to run multiple functions.
It is required to pair the peripheral device speakers, headsets, etc. The AT commands is then sent to the Bluetooth component at the application level, where the action related to the sent command is completed.
Not all of these commands are processed or recognized by all smartphones, as this depends on the manufacturers.
ATFuzzer, the analysis method developed by the researchers, consists of two modules: evolution module and evaluation module, which interact in a closed way.
The evolution module starts with an initial AT command grammar that mutates to generate Psize refers to population size, a parameter for ATFuzzer , different versions of that grammar.
Specifically, ATFuzzer generates new grammars from the main grammar through the following high-level operations:.
To assess the effectiveness and scope of this approach, 10 different models of Android operating system smartphones from six different manufacturers were analyzed.
Upon completion of the analysis, vulnerability testing specialists discovered 4 misbehaviors in Bluetooth and 13 others on USB. By exploiting these flaws, threat actors could deploy malicious activities such as disruption of smartphone connections, denial of service DoS , and theft of sensitive information.
Although security for baseband processors and command interfaces has improved markedly over previous generations of smartphones, it is obvious that with current security measures it is impossible to properly analyze and filter an anomalous input.
