Could your Bluetooth device be hacked in 2020?

When you are living in a world full of technologies made by humans. Anything related to technology can be hacked someway. Your answer to your question which was that could your Bluetooth device be hacked it is yes. It can and I will tell you some ways it can be stopped too. Bluetooth is everywhere in your house from your room to the kitchen and even in the bathroom of some people. Everywhere you can find them very easily Nowadays. Especially when you are using your mobile phone and computer.

Bluetooth vulnerability abound

So what is your Bluetooth vulnerability abound is? I will ask you what have you heard about that in a conference of some official people. They told them to switch their Bluetooth off due to the risk of those things of hacking. Recently they have found there’s a way and a small path to get into your device and hack it. You can call it the manufacturer mistake or whatever but it is now in your device. The hackers do know about it and some do try to hack your device and your personal life too. That is why there was no doubt in that official meeting they switched off all of their devices. Well, that fault that lets hackers hack your device is through technique called key negotiation of Bluetooth.

I’m not as good as the tech people but even I can tell that this thing was no joke. It will allow a hacker to hack your device In a short time of you doing a handshake. The hacker does need to be in a close range when they are trying to hack your device. So what does it do that it forces your device to get weak encryption which let your hacker to crack it and get into your system? It may sound a little confusing and you don’t have to go into the details of it too. Just you need to know as soon as the hacker is in a close range like in the same room with you he or she can now hack your device through this hacking software. He needs a short period of time to get your password and force your password with its new short encryption.

The Boston University found out that the hackers if you are in your Bluetooth device like a headset or any other and its turn on it can know and track you. If the hackers Is nearby and send a public key to your device it has very high chances of that he or she will going to get your session key. Then when it’s done they can easily take it and transfer the data from your device to their and even can send a virus or some mileage message. That’s what it will happen once they are done with it.

It’s the manufacturer fault

This is what most of the creators of antivirus software say and hackers says who works for the government and are on the good side. The simple thing is that it’s not their device that is wrong and that can be hacked. It’s their own process of making that device that is wrong and that cannot be trusted easily at all. So if it’s anyone’s fault, it’s your manufacturer’s fault that you can not be safe.

The McAfee antivirus threat security researcher said that the way they make their device is not a good way to do that. It may be good and useful to certain situations when anyone can connect to it and anyone can use it. But it’s probably not the best way to go when you make something like that. Which is really right why do we need to say the idea of Bluetooth is wrong and we need to stop Bluetooth why not let the manufacturer get it to better.

Let us set a password on our headset maybe for starter and let us change it to whatever we need and want. That way at least it won’t be so easy, there should be a protection software inside your devices that let people get safety or at least let them know there is something wrong going on your device. So what simple thing is that the manufacturers are not giving the proper attention to the security of these devices which I think should not be avoided.…

Do microwaves interfere with Wi-Fi signal?

This is a thing that I have been noticing a lot, Whenever I go near my  small compact microwave and trying to play music and open a webpage. It always messes up with my signal of Wi-Fi, and sometimes I do get it good. But most of the time it is really never letting my phone gets a good signal. So that is why I thought about going into the depth of this problem and what happens. That makes my Wi-Fi always goes down when I’m using both of them together, so let’s start with knowing about them.

What are microwaves?

Microwaves are electromagnetic waves that produce electromagnetic wavelength that gives you the range up to 1m to 1mm. Depending on the obstacles while using it.

What is Wi-Fi?

Wi-Fi is your wireless connection that let your devices to connect with each other and also let your devices to connect to the internet that we mostly use it for. The Wi-Fi is great and probably the most useful need of this generation.

So what happens that makes the microwaves interfere with Wi-Fi?

Electromagnetic radiation

Electromagnetic radiation, we are surrounded by these radiation every day. Like I said that microwaves are electromagnetic wavelengths and this also includes your other devices like TV remote, Wi-Fi and there are plenty more. devices that you will see.

They come in different types, and those types depend on their frequency. When you have high frequency you will find there the Gamma rays and your X rays. Which are mostly used in the hospital and science lab these frequencies can harm humans. While what we using is the low-frequency waves that is your radio waves and microwaves.

Microwave oven and Wi-Fi routers

As I told you that almost every appliance we used in our daily lives are run through electromagnetic wavelength to properly function. And the most common household appliances are your microwave and your Wi-Fi router only. Especially your Wi-Fi router which never turns off for most people. Let me tell you one short thing that I already said they both do need electromagnetic waves to work and function properly. Your microwave oven emits and use microwaves to heat food. While your Wi-Fi uses radio waves to work and provide a signal to your device.

So do they interfere with each other?

In short, yes, they do interfere with each other. You know now that they are almost the same thing, works on the same wavelength and produce electromagnetic waves only. It’s no wonder that they will clash and give some sort of resentment when brought together. it’s just like your magnet north pole coming with the other magnet north pole, of course, they are never going to attract. Same thing with your animals if you bring some species of same-gender you will for sure see a great clash in between them. They tend to clash because of being so much similar. That is why even your microwaves and Wi-Fi do clash and interfere with each other.

So when it starts clashing?

You will notice that before turning your microwave on you will see your Wi-Fi router connection pretty good and with no harm at all. While as soon as you turn your microwave on for heating your food. The Wi-Fi router connection feels those waves and your simple webpage won’t even open. So the reason behind it is super simple that both of their frequency is even the same. They both use electromagnetic waves and then they also use the same frequency of 2.4Ghz. Even though the microwave is not transferring data it still radiates that amount of frequency.

So how can a close microwave oven let that frequency out of its shield? Do you need to consider changing your oven and getting a new one? Is it leaking because it’s broken? There will be lots of questions that will be running through your mind. Well, let me tell you simple things that it’s not your microwave fault it’s just how it is. Even though you get a pack newly microwave oven it will still happen there are always some open spots that are there for your microwave from which the wavelength does get out.

So what you can do?

To be honest mostly nothing, there is one thing you can do but I didn’t do when I found out. You can upgrade your Wi-Fi to 5Ghz which will give you a speed advantage and it won’t interfere with your microwaves. But there was this short-range disadvantage with it. As the lower frequency In a router that is your 2.4Ghz can travel more and give you a better range and I need more than I need 10 minutes of Wi-Fi extra.…
