The Dangers of Bluetooth Hacking and How to Protect Yourself

Bluetooth is the technology we use on many of our electronic devices and wearable technology in Chico and around the nation. It helps keep everything wirelessly connected through our network. It is most often used on devices like our smartphones, tablets, speakers, and home security equipment.

Back in 2018, it was estimated that more than 4 billion Bluetooth devices were shipped. The technology is currently being used in our homes, businesses, and vehicles and is something we can have with us virtually wherever we may go.

But has anyone stopped to consider the risks and dangers involved with using this form of technology? Today we will go over the dangers of Bluetooth hacking and how to protect ourselves.

What Is BlueBorne?

BlueBorne is a vulnerability that was discovered a few years back in several different Bluetooth applications. Security researchers explored this vulnerability back in 2017 and found that it was a flaw present in mobile, desktop, and IoT operating systems. BlueBorne allowed hackers to gain control over someone's devices and then subsequently steal their private and privileged information.

Instead of these BlueBorne attacks being dependent on the internet and these connections, it instead goes through the air. Hackers can silently connect to devices and take over without any kind of user interaction.

What is Btlejacking?

This Bluetooth attack was discovered a year after BlueBorne. It is an attack that allows hackers to jam and take over any Bluetooth device. However, the cyberattack needs to be done within 5 meters of the target. These attacks rely on a jamming vulnerability. All an attacker needs to do is use a Micro: Bit embedded computer that typically costs only $15 along with just a few lines of open source code.

What Is Bleedingbit?

Bleedingbit comprises two more flaws in Bluetooth chips that were found worldwide. These flaws allow hackers to send malicious BLE broadcast messages. It allows them to ultimately corrupt the memory of the device, gain access to the devices operating system, and create a backdoor to execute malicious codes remotely. It is dangerous because there really is no warning when the hackers enter their network, and no security concerns rise.

Preventing Bluetooth Attacks

As of 2020, there are more than 20 billion IoT devices in use. So, to avoid a BlueBorne and other Bluetooth attack, you should take several steps and precautions.

Update Software and Passwords

This is said a lot, but it is very important. Manufactures release regular updates for software and devices that can help minimize your risk surrounding these attacks, viruses, and other malicious acts. Therefore, you should be updating all of your devices regularly while also changing out your passwords frequently.

Turn Bluetooth Off

Another way to help minimize risk is by turning your Bluetooth devices off when they are not in use. It makes you virtually invisible and makes it harder for a hacker to discover the device you are using.

Avoid Public Wi-Fi

Public Wi-Fi connections are not always secure, so they should be avoided as much as possible. Disable these automatic connections on all of your devices in Chico and ensure that you are not connecting to any kind of unsecured network.

If you have any other questions about security and the security of your devices, make sure to contact a trusted security provider in Chico, CA today.

What Our Customers Say

"I had the Alibi system installed several years ago. It has functioned flawlessly. The image quality is exellent both night and day and in all weather conditions. I particularly like the replay (which can be set at various speeds) and zoom functions of the system. Tech support from Crimefreeliving has been excellent. I have received quick responses to questions, and timely home visits — as when I changed IP carriers and my Alibi system needed to be reset. I have recommended Crimefreeliving to several friends."


"As a small business owner here in Chico we definitely saw the need for video surveillance. After expressing our needs and concerns Tim did an excellent job getting us set up with the set up with the appropriate equipment. He really took the time to address our concerns in a very friendly, professional and knowledgeable manner. I highly recommend Tim for all of your business and residential video surveillance needs."

Ron H., Owner/Auto Doctor

"I have to say I love having my security cameras at my home. Tim Truby did a wonderful job of installing the five cameras. He is very neat and cleaned everything up after the installation. He explained to me how to operate the monitor, my phone and IPad. However, I have had to call Tim because I'm not tech savvy and forget what he has told me. He usually just helps me over the phone and then all is well. I'm 80 years old and enjoy the comfort of knowing I have these security cameras."


"Tim Truby designed and installed a 32 camera system for us here at the Butte County Mosquito and Vector Control District. We had received several other quotes from security system vendors, but Tim’s quote was the least expensive. Tim also installed the system quickly and has always been available when we needed him. We are very happy with our security camera system and we can highly recommend Tim Truby for all of your surveillance system needs."

D. Weseman, Butte County Mosquito and Vector Control District

Crime Free Living updated our old video system with a new 16 Channel HD Alibi Video Security System. The old system had been added onto by different installers which resulted in a cabling mess. There were cables that worked and cables that went nowhere. It was a mess. Tim sorted it all out and installed cameras that are very clear. He also installed a monitor for our cashiers to watch hidden areas, a monitor to watch the entry door, and a monitor that allows employees to watch the outside parking and gas pump area. All work was done on time and very professional! Will always recommend Tim and Crime Free Living.

S. AM PM Chico Arco Station

"I had Tim install an Alibi Video Security System at my residence and a couple business locations. The remote view option is invaluable to absentee owners or anyone who travels a lot. The clarity and quality of the cameras have allowed for viewing employee theft. The evidence provided from the HD video cameras was fantastic! Tim was professional and provided extra value from his law enforcement background."

J. Folsom Arco Station

"Tim, I want to thank you again for doing such a fantastic job on installing a wireless IP security camera system at our dream home. The extra time that you took to hide wires, and install a clean, professional system is much appreciated. I still can’t believe the clarity, quality, and ease of use of this new system. I wished that I would have met you before our original inferior system was installed by another company. Now, whether I am at home, or monitoring the system from around the world, I know that my home and family are safe and sound."

John M.

"In April of 2017, my husband and I made a phone call to Crime Free Living that turned out to be a smart and wise decision. Amazingly, in just a few hours, Tim installed four Dome Security Cameras, weatherproof enclosures, and hooked up into our home a 23" Full HD Widescreen Security Monitor. Even more than his professional expertise was the time spent with us in making sure that this system was working correctly and properly installed on our phones so that anywhere in our travels we can monitor our new home in Magalia."

Tieka and Don S.

"I have been using Crime Free Living for the last couple years ar work and at home and I really recommend this product. Tim is a very good service provider. If he can't figure it out, he's got good tech support with the system that he offers."

Gary D.

"I have known Tim for over 10 years. To date, Time with Crime Free Living has installed two separate surveillance systems for my company. With each system, Tim has listened to my needs and custom dsigned surveillance systems for my specific needs and within my budget. The equipment used is always state of the art, the workmanship is top notch, and Tim is the example of trustworthy. I would recommend him for any job."
