These eavesdropping methods can be prevented in this way!


These vulnerabilities are very popular and are the main reason why large companies have GSM signal jammer in their conference halls and senior management offices. This may be the only reason that prevents these devices from transmitting.

We are in the information age. The serious leakage of personal privacy has become the “feature” of this era. Eavesdropping incidents, pinhole camera sneak shots, and vehicle GPS tracking have frequently appeared. In this regard, how should we implement anti-eavesdropping and effective protection What about information security?

Different eavesdropping devices have different anti-eavesdropping measures. We will take these different eavesdropping devices as examples this time to understand the corresponding anti-eavesdropping measures.

①GSM bug

The GSM bug is mainly the same as the original mobile phone. The bug is powered by a battery, usually it is a widely used lithium-ion battery. It consists of a microphone and a GSM module with a local mobile operator's SIM card. Once the eavesdropper detects the noise around it, it only needs to dial a certain phone number, and the wicked person will listen to everything that is happening near the device. The advantages of this device are: a wide range of work, can be used anywhere, with GSM coverage, the installation process is particularly simple. In addition, they are widely spread, and anyone can buy such devices on the Internet. These vulnerabilities are very popular and are the main reason why large companies have GSM signal jammer in their conference halls and senior management offices. This may be the only reason that prevents these devices from transmitting.

②Wireless microphone

The wireless microphone is a convenient device to hide the bug. They include microphones, power supplies and radio transmitters. These small devices can be powered by batteries, but in this case, they can work for a short period of time. The advanced version is powered by the main power supply. These devices are often installed in wall sockets, lamps and other hard-to-find places.

Wireless microphones can use different frequency ranges, and the wide range of propagation is 140-200 and 450-480MHz. The higher the frequency-the greater the transmission range and power consumption. In addition, higher frequencies are easier to penetrate walls and other obstacles. Fortunately, special receivers can be used to detect such devices. But the premium version may have a special signal modulation, and you win; being able to intercept and actually hear them. In this case, you can try to use UHF/VHF jamming equipment to block its broadcast. Cell Phone Signal Jammer

③Network transmitter

Network transmitters are small devices that are installed in various electrical appliances. They collect and transmit information in the low-frequency audio range. They use the grid to send signals and can receive signals from any wall outlet on the same segment of the grid.

The main disadvantage of this eavesdropping device is that the first transformer will destroy the signal, so you must be very close to the target area. In addition, it takes some time to install such a bug because it must be directly connected to the grid. We should also mention that there is no universal way to stop them. You should check all electrical appliances and make sure that no one is suspicious of them.

With the development of modern smart phones, the danger of eavesdropping is increasing, and eavesdropping technology is constantly upgrading. We must be fully prepared to use anti-eavesdropping equipment and take anti-eavesdropping measures to detect and disable eavesdroppers.
