Eavesdropping Attack-Everything You Need to Know

Do you know what is eavesdropping attack is? In today’s article, I am going to share with you, the meaning of eavesdropping attacks, the types of them, and most importantly how to prevent yourself from this kind of attack.

What is an eavesdropping attack?

Eavesdropping is when someone secretly listens to a conversation that was not meant for their ears. It is usually used in the context of spying, snooping, or surveillance. It can be pretty sneaky, and you might not even know that it has happened.

Eavesdropping attacks are also called wiretapping attacks, including traffic analysis, phreaking, phone tapping, voice-mail theft, etc.

What are the types of eavesdropping attacks?

Here are two types of eavesdropping attacks:

1: Direct Eavesdropping

Direct eavesdropping happens when someone picks up an extension or attaches a transmitter to the line so they can hear conversations without being detected.

A common example is when someone listens in on another person’s call at a hotel instead of picking up an extension in their room.

The device used in this type of attack is called a listening device. If you are using an extension when someone picks up the same one, it may be possible for them to listen in on your conversation without you knowing about it.

2. Indirect Eavesdropping

Indirect eavesdropping happens when someone sends the information that is being relayed over a line to another person so they can listen in.

This is often done with modems and fax machines because they send data back and forth to communicate.

The biggest problem with indirect eavesdropping is that it can be hard to detect who is doing it or what they are trying to accomplish.

There are no physical connections like there would be if someone was attaching a transmitter to a line.

Indirect eavesdropping is often used as part of a surveillance attack or to intercept email and voice messages over the Internet.

One example of indirect eavesdropping would be if one user sends you an email and another person intercepts it and reads it for themselves without knowing about it.

They could also send their message but change your original message to don’t know what you sent or received, called spoofing.

This type of attack has been made more common by technologies such as Voice over IP (VoIP), where every call on the network can be monitored, making it easy for someone to tap into conversations that they are not even part of.

Another common example of indirect eavesdropping is when someone hacks into a modem and changes a bulletin board.

Anyone who logs on later will have their passwords stolen or called by people without knowing about it.

This can be done remotely over the phone lines, making this type of attack even more difficult because you don’t know where it is coming from or who is doing it.

How do I prevent eavesdropping attacks?

Eavesdropping attacks are common, and the best way to prevent them is by knowing what to look out for.

1) Find a low-traffic area

One of the easiest ways to prevent eavesdropping attacks is not using public Wi-Fi or hotspots without protection.

Try finding an area with fewer people around you. This will make it much harder for hackers to hack into your phone because there won’t be many other traffic signals around your area (if any).

2) Block all incoming connections

Go into settings > tap on more under WIRELESS AND NETWORKS > turn off Allow Connections. This feature allows Wi-Fi scanning, tethering, device connections, and Bluetooth sharing, making it easier for hackers to sneak into your phone.

3) Turn off Wi-Fi when not in use

Your phone’s location is constantly tracked by the device itself whenever it has an active internet connection.

Thus, if your phone constantly tries to find out where you are, hackers have a higher chance of tracking you down and stealing your data.

This is even easier for them if they hack into public Wi-Fi networks. Make sure you turn off your Wi-Fi once you’re done using it and turn it back on only after you need to use it again.

4) Use a VPN (Virtual Private Network)

A Virtual Private Network encrypts all traffic sent between your computer and another server, making it much harder for anyone trying to eavesdrop on your conversations while using public networks.

5) Do not use SMS and Email while on public Wi-Fi

Never send or receive text messages or emails over unsecured hotspots since hackers can easily record everything you send and receive with their packet sniffer software.

How to detect eavesdropping attacks?

Here are four simple tips on how you can detect eavesdropping attacks.

1. Connect your Bluetooth headset to your device

Connect your Bluetooth headset to your device, then start playing music or any other media file (text or audio).

Then perform a simple Google search for wiretapping Bluetooth see and see if results show up in the top few pages of results.

If so, this indicates that the connection between your headphones and phone has been compromised by an attacker who may be intercepting information like conversations that you’ve had with others through headsets without either party realizing what happening.

2. Connect your device again to another Bluetooth-enabled gadget

Connect your device again to another Bluetooth-enabled gadget (like a smartphone), and use it again to perform online searches for key terms like overhear conversations or eavesdrop on phones.

If there are any shows up within the first few pages of results, this is a clear indication that someone is about to eavesdrop on your conversations on the device through its microphone.

3. Try a different search engine

While performing searches for key terms like “eavesdropping using Bluetooth, or how to hack a phone over Bluetooth, ensure that you do it again on different search engines like Google, Bing, Yahoo, and all the others.

If there are results that fall under the top few pages of searches that you’ve done, this indicates that someone may be listening to what your device can hear either through its microphone or speakers.

Now go ahead and test if it’s true by trying to play any media file (text or audio) on your phone while making sure that nobody else is nearby.

Try also playing some music at varying volumes until you are sure that there are no suspicious sounds or noises made by the phone.

4. Use a different mobile device

Connect your Bluetooth device to another person’s mobile phone. Then perform searches for key terms like eavesdrop victims, Bluetooth spying victims, or how to eavesdrop on Bluetooth.

Suppose all of these returns results fall under the top few pages of search engine results. In that case, this indicates that your conversation with the other party might be compromised by someone who may intercept what you say without either of you realizing something was happening.

The next step is to test it out for yourself and try using a different Bluetooth-enabled gadget like a tablet or smartwatch and start testing out any of the tips on detecting eavesdropping attacks on mobile devices.


That is it, this is everything you need to know about eavesdropping attacks, the meaning of them, how to detect them, and how to prevent yourself from having one.
