If you believe that your cell phone or desk phone is being tapped, there are some clues to support the suspicion. However, some of the symptoms below may be caused by other causes, so be sure to check for multiple signals instead of relying on just one sign. Once you find enough evidence, you can ask the authorities for help. Here are the signs you should look for if you suspect that your phone is being tapped.

Steps

Part 1 of 5: Initial Doubts

1. 

   Pay attention when the secret is leaked out. If confidential information that only a few reliable people know is suddenly leaked out, chances are that the leak is caused by phone eavesdropping, especially if you've discussed the information. there.
   • This is especially notable if you're in a position that makes you an important person to follow. For example, if you are the senior leader of a large company with many competitors, you could fall victim to the undercover industry.
   • On the other hand, the reason you are being eavesdropped can also be very simple, for example you are going through a complicated divorce process. Your soon-to-be divorced spouse may eavesdrop on you if they want to dig up information that is beneficial to the divorce proceedings.
   • If you want to test this, you can reveal a fake (seemingly important) information to someone you trust who won't tell anyone. If that information is leaked out, it means someone is eavesdropping on you.

2. 

   
   
   Be wary if your home has recently been burgled. If your home has recently been burgled but has not lost anything of value, this alone indicates something is wrong. Sometimes the reason is they break into your home to install equipment to eavesdrop on the phone. advertisement

Part 2 of 5: Signs of wiretapping on the phone in general

1. 

   
   
   Listen for noise. If you hear a lot of white noise or other background noises while talking on the phone, there's a chance the noise was caused by eavesdropping device.
   • This is not the most obvious indication, though, as echoes, white noise, and clicking noises can also be generated by random objects, or by poor connection.
   • White noise, noise and sudden noises can be caused by the discharge of two conductors when connected.
   • High-pitched humming is a clearer sign.
   • You can use the low-frequency sound sensor to check for sounds that are not normally heard by the ear. If the volume sounds mixed every minute, chances are your phone has been tapped.

2. 

   
   
   Use your phone in addition to other electronic devices. If you suspect your phone is being tapped, walk over to the radio or television while listening to your next call. Even if you don't hear any interference on the phone, it's possible that interference happened when you stood next to another electronic device, causing white noise with that device.
   • You should also look for signs of interference when not actively using the phone. The phone's active radio signal can interrupt data transmission even when no other software or hardware is installed on the phone, but passive signals cannot.
   • Some audio or wiretapping devices use frequencies that are close to the radio band, so if your radio hisses when set to mono and goes to the farthest position on the frequency band, yes may be one of those devices in use.
   • Similarly, wiretapping equipment can interfere with TV broadcast frequencies on UHF channels. Use a TV with antenna to check if there is equipment interfering in the room.

3. 

   Listen to the phone when not in use. Your phone will make no sound when you are not using it. If you hear beep, click, or other sounds from the device when not in use, eavesdropping software or hardware may be installed in the device.
   • Specifically, you need to listen to the white noise emitted by the amplitude.
   • If this happens, it can be concluded that the microphone and loudspeaker are working even when you are not using the phone, the cause is that an electrical circuit is tangled into the phone. Any of your chats within 6 m around the phone may be eavesdropped.
   • On a landline phone, if you hear a dial tone when not using the phone, this is a sign of eavesdropping. Confirm the presence of this noise with an external audio amplifier.

Part 3 of 5: Signs of wiretapping on mobile phones

1. 

   Pay attention to the battery's temperature. If the cell phone battery becomes unusually hot when not in use and you do not know why, there may be eavesdropping software running in the background, causing the battery to continuously drain.
   • Of course, hot batteries can also simply be caused by overuse. This is especially true if your phone is more than a year old, as cell phone batteries deteriorate in quality over time.

2. 

   Note the number of times to charge the phone. If the battery life of the phone suddenly drops without a reason, forcing you to charge twice as many times as normal, it might be because the wiretapping software is constantly running in the background and draining all of the power.
   • You also need to consider your phone usage. If you have been using your phone a lot lately, the need to charge more is probably simply because the phone works more. This is only true if you barely get to your phone or use it more than usual.
   • You can monitor the battery life of your mobile phone using applications such as BatteryLife LX or Battery LED.
   • Note that cell phone batteries reduce the ability to hold electricity after a period of use. If the change happens after you've been using the phone for a year or more, it's simply because the battery is old.

3. 

   Try turning off the phone. If the power off is delayed or cannot be completed, this bizarre condition indicates that someone is controlling your phone through a device that is jammed onto the circuit board.
   • Pay close attention to assess whether your phone has been powered off for longer than usual, or whether the backlight continues to light after you turn off the power.
   • While this could be a sign that the phone is being eavesdropped, it could also be a hardware or software malfunction in the phone that is completely unrelated to the wiretapping.

4. 

   Watch out for random activities. If your phone turns on the screen by itself, turns off the power, starts up, or installs an app by yourself without you interfering with it, someone may have cracked it and controlled it with a device that stuck to the board. .
   • On the other hand, this situation can occur if there is accidental intervention during data transmission.

5. 

   Pay attention to unusual messages. If you have recently received SMS messages that include any string or numeric string sent from an anonymous sender, those messages are a very clear indication that the phone is under control.
   • Some programs use SMS texting to send commands to the controlled phone. If these programs are poorly installed a message may appear.

6. 

   Pay close attention to the phone bill. If data costs skyrocket and you know you're doing nothing to increase costs, then maybe someone is using your data through a tracking device or app.
   • Many tracking programs send call history to servers using your mobile data. Old programs use a lot of mobile data so they are easy to detect, but new programs hide better because they use less data.

Part 4 of 5: Signs of wiretapping on desk phones

1. 

   Check out the space around you. If you suspect eavesdropping on the phone line, you should check the surroundings. If something is misplaced, like a sofa or desk, don't assume you are hallucinating. This could be a sign that someone has sneaked into your home.
   • An eavesdropper may have moved furniture while trying to access power lines or phone lines, so this is an important factor to be aware of.
   • Specifically, observe the wall panels. You should pay close attention to the walls around the phone. If they seemed to have been teleported, someone might have interfered.

2. 

   Look outside the phone box. You may not know what the inside of the box looks like, but if you know a little bit, take a look. If the phone box seemed to have been disturbed or the contents had been affected, someone might have approached to install the device to eavesdrop.
   • If you find any hardware installed in a hurry, even if you don't know what it is, have an inspector.
   • Look closely at the "restricted contact" side of the box. This side of the box can only be opened with a hexagonal key, and if it seems to be affected then there must be a problem.
   • There is only one box per landline number and there are two cables connected to the box. Any additional cables or boxes may be a sign of eavesdropping.

3. 

   Count the number of multi-purpose trucks running through your house. If you suddenly see a lot of multi-purpose trucks running around your house, this may be a sign they are not ordinary multi-trucks. It is the vehicle of the people who are eavesdropping on your calls and they have a wiretapping line on.
   • This is especially noticeable if no one gets in or out of the car.
   • In general, people who eavesdrop on a landline phone line through a recording device will be 150-200 meters away from your home. The vehicles will be fitted with stained-glass doors.

4. 

   Beware of mysterious repairmen. If someone comes to your home claiming to be a repairman or an employee of the telephone operator, but you don't ask them to come, then it could be a trap.Verify the person's identity by calling the phone company or company they claim to have come from.
   • When calling that company, you should use the phone number in your phonebook. Don't use the phone number given to you by that person.
   • Even if you have verified it, you must still carefully observe the mechanic's actions while they are in your home.

Part 5 of 5: Confirming your suspicions

1. 

   Use an eavesdropping device. An eavesdropping device can be installed on your phone. As its name suggests, it can pick up outside signals and wiretapping devices, let you know if your suspicions are correct, and whether someone else will eavesdrop on your calls.
   • The usefulness of this device remains questionable, but for the device to detect eavesdropping it must detect but changes in electrical or signaling on the telephone line are checked. Look for equipment that can measure impedance and capacitance, along with the ability to detect changes in high frequency signals.

2. 

   Install apps. For smartphones, you can set eavesdropping detection application to detect eavesdropped signals and unauthorized access to the phone data.
   • The effectiveness of these types of applications is still subject to debate so they may not be able to produce conclusive evidence. Some of these applications can only detect recording devices installed with another application.
   • The app that claims to be able to detect the recording device is Reveal: Anti SMS Spy.

3. 

   Ask for carrier's assistance. If you have good reason to believe your phone is being tapped, you can ask your carrier to check it with a dedicated device.
   • The standard analysis performed by the telephone company can detect all cases of illegal eavesdropping, eavesdropping equipment, low frequency equipment, and phone line coupling.
   • Note that if you asked the telephone company to check the wiretapping and recording, but they declined the request or confirmed that nothing was seen after looking through the speaker, then it is likely that they are doing the request. government demand.

4. 

   Go to the police station. If there is clear evidence that the phone is being tapped, you can ask the police to check it. Also, ask them to catch someone who is eavesdropping on you.
   • Most police stations have equipment needed to check audio or wiretapping equipment on the phone, but if you don't have the right evidence they won't use it.
