How To Hack A Bluetooth Speaker

You are traveling on a bus, but you feel the music on the deck sucks? Or maybe your neighbor is having a party at home, and you can’t stand the noise? You can actually take over the Bluetooth speaker and play what you want. In this article, we will show you how to rob a Bluetooth speaker. Read this article to learn more.

Can I hijack or attack the Bluetooth speaker?


The first question you should ask yourself before undertaking this endeavor is whether it is doable. The answer is yes! It is possible to bypass the security of a Bluetooth speaker, hijack it or hack it, and take full control of what plays on the speaker. However, the process is technical and has some security barriers.

Are Bluetooth devices safe?

If we answered yes to the previous question, does that mean that Bluetooth devices are not secure? In general, researchers still consider Bluetooth as a cheap and popular means of information sharing, so it is widely used on devices such as smart watches, speakers, game controllers, etc. headsets and IoT devices.Additionally, recent research shows that Bluetooth speakers are vulnerable to the recently discovered Bluetooth Master Negotiating (KNOB) attack. With this type of vulnerability, intruders can gain complete control of a Bluetooth device without the victim receiving any signal or warning. In addition, the hijackers can seamlessly use this protocol to carry out additional covert attacks on the device they attack, such as monitoring Bluetooth chats.

What is Bluetooth KNOB attack?

Bluetooth is a standard that allows two paired devices to negotiate. When devices negotiate, one of the things they have to agree on is encryption. The Bluetooth Knob attack or Bluetooth Master Negotiating Attack (KNOB) exploits a critical vulnerability in the Bluetooth specification that allows anyone to circumvent Bluetooth’s security mechanism. Bluetooth devices require different levels of security for the connection. This is great for communication as it increases device compatibility and ensures that the new device can still communicate with the old device. However, the attack takes advantage of a vulnerability that makes it easy for an attacker to force two devices to use weak encryption. When this happens, the KNOB attack reduces the entropy of the link to 1 byte. In general, the entropy level determines how much encryption changes over time, and it is the most important determinant of Bluetooth security. When coding is weak, fundamental changes are slow. As a result, account hijacking becomes much easier. As a result, a nearby hacker will force your device to use weaker encryption when it connects, leaving your device vulnerable. Bluetooth devices you have connected. Besides, he has a brief time window to interrupt the handshake and force a different encryption method.

How to hijack Bluetooth speakers

However, hijacking a Bluetooth speaker may not be a straightforward process. You can hack Bluetooth speakers using Android, iPhone or Linux.

How to Jam Bluetooth Speaker with Android or Iphone

Escalate the attackYou should be able to hijack the Bluetooth speaker by switching the KNOB attack first. With KNOB open, escalate the attack one step further by leveraging your access to a decrypted link in a controlled environment and Bluetooth session hijacking.Set up a man in the middle of the attackAfter using KNOB to crack the link, escalate the attack by setting up a Man-in-the-Middle (MITM) relay. To complete the attack, you’ll need to write a Python script to change the session that runs through the Person in the Middle Transition before transmitting the changed packets. You can do this by changing the stream of music sent to the speakers. Note that you should be able to take over the speaker without any indication to the victim that the session is being hacked except for a change in the music or audio signal.

What Do I Need To Hack Bluetooth Speaker With Android Or Iphone Successfully?

You will need some of the following software packages, a Raspberry Pi 3B+ and a rooted Nexus 5 smartphone.Blue insideThis is a test that researchers use to get low-level Bluetooth access to devices. It can log traffic, send packets, dump memory, set breakpoints, push assembly points and many other functions.GatttoolThis is a utility to discover Bluetooth Low Energy (BLE) devices. It is a modern branch of the core Bluetooth standards with specific energy-saving features. The researchers are particularly interested in the Bluetooth Low Energy standard because it allows users to probe devices for information even when they are not paired.BtproxyIt helps researchers build a MITM relay that helps analyze traffic between two devices. Intruders use btproxy to eavesdrop on Bluetooth devices and inject their data into the connection.Read more: how to add fonts to firealpaca | Top Q & AI If you are a Bluetooth system researcher or want to try some Bluetooth hacks, these utilities will help you carry out your plan without interruption.

How to hack Bluetooth speakers with Kali Linux

You should be able to hack Bluetooth speakers using Btscanner in Kali Linux. You can use this tool to capture recordings from Bluetooth devices even when not paired.Download the software, set it up, and search for the speaker device you intend to hijack.

  • Start your Bluetooth with the SYNTAX command: -SERVICE BLUETOOTH START
  • Open btscanner with above command
  • Follow the prompts
  • Select the arrow keys shown and press enter for full device details.
  • You can then perform any action like accessing and playing music using your chosen device.

Why is it so difficult to perform Bluetooth attacks?

As we mentioned, hacking a neighbor’s Bluetooth speaker might not be such an easy task. This is because the Bluetooth hack requires you to be there during the Bluetooth device pairing process. Otherwise, you must force the devices to re-pair. However, forcing devices to re-pair requires you to take advantage of a hardware vulnerability or disrupt the connection by making noise. re-pair the attacks and expose the attacker using a high power multichannel frequency jammer to generate enough interference to warrant an interrupt. Besides, it is illegal to use any jamming device.

How do I protect my Bluetooth speaker from attack?

In the same way that people can gain unauthorized access to a Bluetooth speaker for ethical reasons, others can do so for unethical reasons as well. Follow the instructions below to secure your Bluetooth devices:

  • Avoid having sensitive conversations over your Bluetooth device
  • Avoid using Bluetooth Internet adapters
  • Do not use Bluetooth devices when communicating with virtual assistants
  • When buying Bluetooth devices, look for ones with Bluetooth 5.1 or higher
  • Turn off Bluetooth on your computer and phone when they are not in use
