Jammers can intercept and destroy signals

We have heard a lot about the Internet of Things, where more and more devices are connected to the Internet. However, in addition to the fact that these devices are connected to the Internet, they are also increasingly using various radio frequencies to connect or be controlled by them. These radio frequencies usually use proprietary or insecure protocols, and there is usually no need to intercept the signal to destroy the signal, but just block it.

A recent case in Manchester shows how vulnerable our dependence on radio frequency is. In this example, the thief used a simple car lock jammer to break into the vehicle, causing serious damage in the parking lot, no one could unlock/lock their remote car lock, and eventually multiple alarms were triggered.

In North America, the operating frequency of car locks is 315 MHz, and in Europe and Asia, the operating frequency of car locks is 433 MHz. Although signal jammer are illegal in most countries/regions, in many places, these devices sell these frequencies for around US$50 to US$200, depending on the scope and quality of the equipment.

I hear a lot of people who “cut the wires” who claim that they are no longer connected to the cables. Even more disturbing is the fact that they brag to the public online through social media. It puts people in danger, and many people ignore this danger. Potential thieves or home intruders are now suffering a major blow. If they are even smarter, they will take advantage when they invade your house. Like car lock jammers, cell phone jammers are illegal but still easy to find.

The cell phone jammer batteries can be purchased and sold by means of they must be shipped to US residents and other countries, even if they are illegal online sites. Using a mobile phone jammer may result in a fine of $20,000 or less. However, if criminals can buy guns without a license, it is not difficult to put their hands on the mobile phone jammer.

If a thief or an intruder activates any of these devices from outside the home, the phone will no longer be able to receive signals and you will not be able to make any emergency calls for help. Many of these jammers can also disrupt Wi-Fi, so just tap the switch on these devices to easily turn off all communications in the house.

Although more and more people are “cutting the wires”, this has also caused problems for traditional alarm systems that rely on land lines. If the ground cable is cut, an alarm is usually triggered at the alarm monitoring station. Nowadays, alarms can be wired via an Internet connection or using a cellular connection. However, these two new methods have problems. If the Internet or cellular connection is disconnected, the alert provider is usually not alerted. A thief can easily cut off the Internet connection from outside the house, and we already know what can be done with a cell phone jammer.

Many operators sell other home automation and security equipment and services, from alarm systems to cameras and locks. However, when the mixer is introduced into the mixer, whether these equipment and safety measures can work properly is a question, especially as criminals become more familiar with the technology. These jammers can also disrupt industrial systems and receive several blocks of block units with enough power. Therefore, it is conceivable that these types of tactics can not only be used by criminals, but can also be developed into means of attack.
