WiFi jammer can isolate all cyber dangers

In the Wi-Fi Security Blogging Trilogy, I will feature an occasional opportunity that I encountered while jamming Wi-Fi signals. WiFi, especially in the UK, has seen some WiFi explosions recently. In the UK, entire urban communities are already WiFi compatible. There is no doubt that we will depend more and more on WiFi networks. Anyone who has read an official book on computer security will have a full understanding of the CIA when it comes to security, the triad of confidentiality, integrity and usability. This article will discuss uptime i.e. blocking WiFi signals. Now jammer-mart.com has better wifi signal jammer that can help you.

5 bands portable jammers

A few weeks ago, I finally gave in and bought a Nintendo Wii console for my kids. I think it keeps them physically active while playing video games, and I think that’s right. Anyway, I put the Wii under the main TV and then try to connect the Wii to my home Wi-Fi network, which will allow the Wii to receive software updates, weather forecasts, and even browse the web using the Wii Opera web browser. It was quickly discovered that the Wii could not connect to the WiFi network.

Therefore, after an hour of troubleshooting, temporarily removing all security from my wifi jammer and plugging the wifi router into Wii as close as possible, I found that Wii was not able to receive signals from my WiFi network at a distance of up to 10 cm! Even so, the bandwidth (network speed) still seems too slow. Well I gave up the day because the kids wanted to play Wii sports. I just thought the Wii’s Wii Card was risky, but later that night I encountered an eye opener while watching satellite TV on the bed.

You see, I have satellite TV and it feeds the main TV. But, earlier this year, I wish I could watch all these beautiful satellite TV channels on my bedroom TV. So I bought an inexpensive “Technika” broadcast solution. Local supermarkets cost £ 20 (around $ 40) instead of paying more to satellite companies to buy a second set-top box, Sat Box. The device consists of a broadcasting unit which is connected to the scart output of a satellite television decoder. The broadcast unit sends TV images, sound and even infrared signals from the remote control to the receiver, which is connected to the scart input on the TV. From the room. My epiphany is that in theory the broadcast TV unit blocks the Wi-Fi signal, especially since both the Wii and the TV broadcast service are under the main TV. So I turned off the TV streaming equipment and immediately connected the Wii to the Internet.

The next day I did some experiments with my laptop. I noticed that the TV broadcast unit was on; in some parts of the house the signal strength of the WiFi network has been reduced by two-thirds, and downstairs all connections to the WiFi network have been removed.

Therefore, an efficient Wi-Fi jammer can be obtained at a very cheap cost. I think with some custom settings we can expand the range of Wi-Fi interference and make it a mobile device, I can think of many bad uses of WiFi interference, especially to cause other attacks, but a good one practice may no-WiFi policy, although you may need to check applicable laws. broadcast.

Car theft: jammers, a new weapon for car thieves

This is not a rumor or even a potential risk (like a security breach), but a reality: car thieves have a new way of behaving and it’s unfortunately very simple and very effective. The National Police released an official press release on May 19, 2020 warning of “frequency jammers” that allow thieves to block the automatic closing of car doors … to safely search or steal them.

A simple, inexpensive box for a few tens of euros

The signal jammer is neither complicated nor large: it fits in one hand and only blocks the signal that the remote control sends to the car when the doors are closed (automatic remote locking). The signal is encrypted, the car remains open.

What worries the authorities is that it is extremely easy to get this type of jammer on the internet and in parallel markets. Their prices also make them dangerous: barely fifty euros or accessible to everyone. Suddenly their shadow multiplies in Ile-de-France and all over France.

The only solution: vigilance

If the police can watch, they arrested three young people in the act on May 12-15, 2015. The number of cars and jammers in circulation is far too many for the police to check. And there is nothing to be done about these boxes.

To do nothing except … be vigilant as always. The problem is that with a remote lock you are more likely to trust not to check that the doors are actually closed: generally, you press the button as you step away from the vehicle and without returning.

But thieves watch with their boxes. However, if you are vigilant and check that the doors are actually closed, there is nothing they can do: if they are not closed, you can always press the button again to close them or stay near the vehicle while they are closed are not close.

GPS Jamming Experiment

Chronos Technology Ltd successfully demonstrated the GPS Jammer Triggered Camera technology during official GPS jamming tests at the Sennybridge Military Jammer Training Area in Wales at the end of August 2015, Lydbrook , Gloucestershire, UK.

JammerCam ™ GPS triggered camera technology Jammer was jointly developed by the Department of Electrical and Electronic Engineering at the University of Bath and Chronos Technology Ltd. This development took place within the framework of a project called “AJR”. Internet of Sensors “Feasibility study competition

The trials allowed JammerCam ™ units to be tested in an outdoor environment with a range of GPS jammer hidden in vehicles passing alone or in convoys, including cars, vans and shipping containers. Jammer-triggered camera sensor technology successfully identified and photographed the vehicle hosted by the jammer in all test cases and at all speeds and powers. Either way, the vehicle was taken at the center of the frame so that only one frame was needed, which significantly reduced the bandwidth needed between the sensor and the web server.

The photo identifying the vehicle with jammer would then be sent over a mobile network to a web server where it is distributed as a hyperlink to target email addresses. The image can then be called up as actionable intelligence within seconds of the camera taking the jammer.

Professor Charles Curry, Managing Director of Chronos, explained: “A proof of concept system was demonstrated during the Sennybridge GPS Jamming trials in 2014 by the University of Bath. We then had to overcome some significant challenges, not the least of which was to make the system fully automatic so that it only took a photo of the vehicle hosting the jammer. We know that even low powered cigarette lighter style jammers emit enough detectable interference to create a power bubble around the vehicle, making it very difficult to determine which vehicle in heavy traffic is hosting the jammer. Our two biggest discoveries were to identify the vehicle in a convoy hosting the jammer, and detect and catch a shipping container with a low-powered jammer inside.

Jammer at university

Along with the advancement in technology, the cheating has also been high tech, the use of mobile phones, wireless headphones and bluetooth devices to get the answer. Many people even hid a transmitter in the examination room.

“The jammer will block the movement of the electronic device, Wi-Fi and Bluetooth operations. Once the body is finalized, the BPSC will be close to the center to clean to install the jammer,” an official said.

The interference operator must be responsible by the supplier concerned in order to avoid local tampering in the inspection center. The jammer effectively turns off the cell phone. They are transmitted at the same radio frequency as the mobile phone, thereby interrupting communication between the phone and the mobile phone’s base station in the tower.

Desktop 5g jammer

Although cell phones were banned in the exam hall, the last year of MBB students at a private university managed to cheat on recent exams using bluetooth devices and microphones. “We have installed mobile phone jammers in four exams to prevent cheating during exams. The education department has also been tasked with closely monitoring the flow of students and carefully examining suspects.” The dean said.

At Kyoto University in Japan.

Cell phone jammers have become the focus of interest after recent events of fraud at Kyoto University and four other prestigious university entrance exams.

This gsm jammer transmits radio signals in the 800 MHz band and serves as the main carrier frequency band for NTT DoCoMo and KDDI phones at. May also supply products for other groups.

Currently, the main business users of 4G Cell Phone Jammers are hospital, concert hall and movie theater operators, and some banks are also installing ATM equipment to prevent “minor” fraud (that’s me. , It’s me).

In the phone scam, criminals usually through the phone to guide the elderly to the fraudulent person’s temporary bank account, pretending to be relatives or acquaintances suddenly under financial strain. According to the merchant of mobile phone jammers, the university has now been added to the list of customers.

Norway warns pilots of GPS jamming near border with Russia

The Norwegian aviation regulator has warned pilots about jamming satellite navigation signals, including GPS, in Finnmark province, bordering Russia’s Murmansk region, The Barents Observer reported.

The warning was made the day before to the NOTAM operational base (changes in the rules for conducting and ensuring flights and aeronautical information) until January 31, the newspaper notes. SAS, Norwegian and Wideroe planes fly through the specified area, but the pilots of which of the airlines noticed navigation problems is still unclear, the resource writes. The Barents Observer emphasizes that the reason for the NOTAM warning is the complete loss of the navigation signal.

gps jamming device

In November 2018, Finland accused Russia of jamming the GPS signal during NATO’s Trident Juncture exercise, held from October 25 to November 7. The GPS malfunction was discussed with Russia at the diplomatic level, and the Finnish Foreign Ministry also summoned Russian ambassador Pavel Kuznetsov on this matter. The Norwegian Ministry of Defense also made similar accusations against the Russian military group in the Arctic. True, it admitted that the navigation disruptions did not lead to any serious consequences.

The press secretary of the Russian President Dmitry Peskov then said that the Kremlin did not know about Russia’s involvement in failures in GPS systems, and forwarded the question about this to the Russian Ministry of Defense.

Do we really need to install a cell phone signal amplifier?

We can often see mobile phone signal amplifiers installed in many places such as tall buildings, basements, shopping malls, restaurants, karaoke saunas and massages, underground civil air defense projects, subway stations and many other places to solve these signal blind areas and weak areas. Poor problem. But do we really need to install a cell phone signal amplifier?

cheap portable wifi signal jammer

1. With the rapid development of my country’s economy, the requirements for mobile communication services are getting higher and higher. The rapid development of mobile communication and the rapid increase of mobile users have resulted in smaller and smaller cellular plans and smaller and smaller coverage areas of mobile phones.

2. With the rapid development of the city, the planned use area of ​​the city is getting smaller and smaller, and the tall buildings in the city are being built higher and higher. The signal base stations on the back of these tall buildings or underground are blocked by the high-rise buildings, and the signal attenuation is serious. The mobile signal received by the mobile phone also weakens.

3. With the rapid development and renewal of the city, the decoration level of the exterior of the building has also improved. The commonly used metal steel structure, aluminum alloy structure, etc. absorb and reflect the signal, making the mobile phone users in the building unable to normally accept the outdoor Cell phone signal

4. Due to the blocking and reflection of electromagnetic wave signals by buildings, some places in closed buildings, such as shopping malls, supermarkets, KTVs, bars, underground parking lots, etc., cannot actually receive external mobile phone signals normally.

In view of the above four points, in order to make normal communication between mobile phones, normal calls and Internet access, we need to install a set of mobile phone signal amplification equipment to amplify the normal signal from the outside of the mobile phone to the place we need, and give it to the inside Staff or customer personnel bring the convenience of mobile phones.

YX-007, a global all-recording jammer (jammer), was born in Incom!

As the name suggests, the recording muting device is an instrument for shielding recording. In today’s society, information is rapidly developed. The problem of voice information leakage is a difficult problem to solve in the world. People’s normal conversations are recorded silently and reprocessed out of context to become a means of coercion by people with ulterior motives, which involve national security. Important information is illegally recorded and spread, becoming a security hazard!

For this reason, Tianjin Yingxun Technology Co., Ltd. has developed a sound signal jammer product with great concentration. This product can effectively prevent illegal sound collection such as mobile phones, voice recorders, video audio parts, recorders, etc. According to the needs of users, the company has developed several products covering handheld to desktop, meeting the various needs of meeting rooms and individuals.

In addition, the company’s products have obtained authoritative inspections by the National Security and Alarm System Product Quality Supervision and Inspection Center of the Ministry of Public Security and the Ministry of Public Security’s Safety and Police Electronic Product Quality Inspection Center to ensure the quality of the products.

When the YX-007 series recording muting device is recording, the recording muting device will generate random noise signals, which can produce suppressive interference to the voice signal, so that the recording equipment picks up only noise information, and cannot distinguish the voice information. Ensure the security of voice information. Widely used in: leadership offices, confidential meeting rooms, military war rooms, business negotiation rooms and other places that prevent recording.

Why drones become a nightmare at British airports

London’s Gatwick Airport (Gatwick Airport) has been closed for more than one day under the influence of drones, affecting more than 700 flights and affecting approximately 100,000 passengers. The local police have yet to find anyone operating the drone, but they suspect that it may be the work of environmentalists.

A Gatwick Airport spokesperson pointed out that the British police and military have provided additional precautions for the airport to allow the airport to reopen and allow aircraft to take off.

Many drones are now cheap, and you can buy them for as little as tens of dollars. But the BBC science and technology reporter Jane Wakefield (Jane Wakefield) reported that these small aircraft can have a huge impact on civil aviation traffic.

What is the impact of drones on aviation safety?

A UAV collided with a civil airliner at an airport in Canada in October 2017. The wing was slightly damaged, but it still landed safely afterwards.

We are not yet fully aware of the consequences of a collision between a UAV and a civil airliner. Many organizations have done relevant research to simulate the consequences of collisions between drones and passenger planes in different situations, but the conclusions of each test seem to be different.

The University of Dayton in the United States simulated a collision between a one-kilogram drone and a civil aircraft flying at 383 kilometers per hour. The results showed that the passenger aircraft was seriously damaged.

If there is a drone jammer gun, will the situation be better?

The UAV counter-gun is a kind of electromagnetic interference equipment with a gun type, which is not only a gun type but also a splint type. The principle of this weapon is to emit electromagnetic interference waves between 2.4GHz and 5.8GHz, interrupting the connection between remote control equipment and drones. Because most drone remote controls are also in this frequency range. The operating distance is within 1000 meters, which can force the long-distance low-altitude drone to fall, return to the operator or descend smoothly in a short time, thereby realizing effective control of flying drones in the “control area”.

Anti-drone technology is necessary in the future

Anti-UAV technology, why is it essential for airports.

With the dramatic increase in drone penetration in the past few years, controlling the sky above us has become an additional responsibility. UAV detection solutions have become very important, not only can detect long-distance UAVs, but also access a variety of potentially important information, such as controller location and UAV model.

Who are those organizations that rely on drone detection? The police force certainly bears a great deal of responsibility when tracking illegal activities involving drones, but the airport (probably more than any other type of venue) must fully control the sky above its location. As drones increasingly enter the airspace around airports, this reality has become more relevant in recent times.

Last summer, a drone entered the airspace near Gatwick Airport, causing five aircraft to be diverted and completely closed the runway.

In addition to endangering the safety of passengers on board, taking up air traffic control time, and causing inconvenience to people who eventually misplace or put their journey on hold, it can be said with certainty that the interruption of drones will eventually cause great losses to airlines. All these problems are caused by a relatively small unmanned aerial vehicle, which emphasizes the importance of airport drone detection.

According to this BBC article, the British Airprox Commission conducted an investigation into the Gatwick incident and concluded that the incident caused as many as 130 deaths.

Time for action

The truth is not a lie. According to Airprox’s data, in the last two years of records, 168% of aircraft errors on drones and aircraft. The drone caused chaos around the airport, stopped flying, almost lost the aircraft and caused delays.

In December 2018, a drone report at Gatwick Airport grounded all flights and disrupted thousands of passengers within 24 hours. Fortunately, there is a solution to these problems and return more control to those who work on the ground.

UAV automatic detection and defense solutions can let people know those who pay attention to the sky. UAVs can now be detected up to 20 kilometers away, and early warning can give precious time to prepare and deal with any type of UAV threat.

drone jammer gun high power

The ability to identify the location of the controller gives the airport the opportunity to more effectively liaise with law enforcement agencies to take action against those who violate its airspace. It can identify a specific drone model and the actual serial number of a single drone that has been detected. This is enhanced by the flow of information to be able to pinpoint the heading, speed and altitude of the drone-all potentially key facts that could affect the actions taken by air traffic control.

Portable drone jammer has become a popular anti-drone technology option, suitable for police forces that require drone detection on the move, but when it comes to airports, the fixed version may see the most demand .

6 ways to prevent decoder theft

When the car owner locks the car, it intercepts the decoded signal sent from the car’s key to the car’s central control lock device, analyzes the frequency and data in it, and copies this signal to control the car door lock and easily steal the owner’s car or car property.

The car GPS jammer has a low technical content. The principle is to send out a frequency similar to the original car key signal, and the signal is strong, covering the original car key signal, making the vehicle unable to lock the door, and taking the opportunity to steal the property or the vehicle after the owner goes away .

car gps anti track blocker

“This kind of device is a decoder, rather than a codecutter, because it mainly relies on intercepting the signal to copy the signal.” Master Su said, the public need not be too panic, because only when the owner of the car is opening or locking the car, it is illegal. Only the disciples can take advantage of it. However, in order to avoid property damage, Master Su reminded the majority of car owners to be more careful when parking.

Learn the following 6 tips to reduce the chance of theft of vehicles and their belongings:

1. When you lock the car, pay attention to whether there are suspicious persons within 10 meters.
2. When locking the car, the owner should not be too far away from the car to reduce the range of sensor sensing by the decoder.
3. When using the car anti-theft alarm, install a mechanical anti-theft device and install several concealed locks, such as steering wheel locks and gear locks, so you are not afraid of any decoder.
4. Look for a more side-by-side anti-theft method, do not install the anti-theft device in a fixed position, which increases the time of the thief’s crime, and the thief will lose patience, thereby reducing the chance of successful theft.
5. Load the GPS global positioning system on the car. Even if the car is stolen, the police can quickly locate the stolen vehicle and retrieve the stolen vehicle as soon as possible.
6. It is still necessary to emphasize that you should not put valuables such as leather bags, mobile phones, cash, etc. in the car to avoid losses caused by criminals.
