Signal Jammer Tech

  

Tom's Guide tested an incongruous object: a cell phone jammer hidden in a pack of cigarettes.

There are various models, which are said to have a radius of action of 5 to 50 meters, and are sold for between 50 and 200 euros. The tested one is quite economical: 80 euros for a radius of 8 meters. Vicious: "Its makers have resized [the box] to make room for the two actual cigarettes in the pack".

The appearance and legitimacy of the product are not as good as it should be. "One thing's for sure, it didn't pass customs," the tester noted.

But why buy such a device? A salesperson interviewed offered some explanations: Some people disrupt communications in public transport, some teachers want quiet in the classroom...

It all started when two mobile operators reported mysterious disruptions to their networks in and around Clermont-Ferrand. ANFR then dispatched two agents from Lyon. Their measurements confirmed that the signal was interfering with the mobile network from Clermont, but locating the source of the interference was "like finding a needle in a haystack in a city of 140,000 inhabitants".

Investigators will get there. The roof of their laboratory vehicle is equipped with a radio direction finder, a device that can locate the direction of the transmitter and direct them to a building in Clermont. Six elite police officers from the Belt and Road (Research and Intervention Team) then intervened. Balaclava, helmet, assault rifle, they tumble into the apartment, and in the drawer of the TV cabinet, we find a multi-band gps blocker.

Paris Olympics 2024: Lasers, Interceptors, jamming signal Rifles... These Weapons Against Drones

From lasers to drone sensor drones, with less than a year to go until the opening ceremony of the Paris Olympics, these weapons have been honed in the face of now very real threats from the skies.

How to effectively counter aerial threats in the form of nearly invisible machines at lightning speed over crowded stadiums without causing collateral damage? The security of the Paris 2024 Olympics will not be able to avoid this question. In response to any suspected drone intrusion during this global event, security forces will deploy an unprecedented arsenal.

  

A truck driver was arrested on Monday for using a GPS jammer to hide his geographical location from his employer for several weeks, interfering with signals received by civil aviation at Lyon Airport

He blurred the path of the truck, as well as the path of the plane at Saint-Exupery Airport. A truck driver was arrested in Olins, south of Lyon, on Monday morning for using a GPS jammers to mask the geographical location of his professional vehicle, several sources with knowledge of the matter confirmed to Le Figaro. The National Radio Frequency Agency (ANFR) conducts 1,800 such incidents every year, and after an investigation, the suspect was arrested by police on the CRS highway. It is the General Directorate of Civil Aviation (DGAC) Lyon Airport that sees its GPS signal being interfered with at the same time every morning, thus issuing an alert. After a month of investigation, the direction finder - a circular radar placed on the roof of an ANFR vehicle - was able to isolate the HGVS travelling at the relevant time and identify their number plates.

Petty theft and serious crime

The Lyon driver told police he was trying to escape his boss's supervision. "This is the most commonly used," Gilles Bregant commented. People move through geolocation enabled corporate devices and for some reason don't want to tell employers where they are. On CNil verified devices, there is a button to suspend geolocation, but the employer knows it has been activated." So there are sometimes good reasons to avoid layered regulation. A few years ago, ANFR spotted a mixing truck in Lyon taking a short detour to deliver concrete to an acquaintance. Again in Marseille, tanker drivers deliver a few litres of petrol to a petrol station that has industrialised the process. Not enough to put the chip in the controller's ear. Except that the station is located in the disturbance zone of Marignane Airport. In addition to these small frauds, the use of signal jammers can also indicate more criminal behavior, "where people believe they are being watched by law enforcement or other gangs, suspect trackers and use jammers to turn them off."

"It's a very harmful little device," Bregant said, but it can't be used for malicious purposes against airports because GPS is not a landing instrument. "There are specialized instruments on other frequencies that can allow landings," he said. GPS is just used to make the situation more reliable." But these jammers also interfere with planes announcing flight plans because they need to give their position.

The ANFR director assured that in the context of the war in Ukraine, more powerful phone jammer were used for military purposes, especially to interfere with the operation of drones and the geolocation of artillery fire. "In Moscow, when fears of strikes in Ukraine grow, sometimes taxis can't find their way around."

How to prevent network eavesdropping attacks

A network eavesdropping attack, also known as a network sniffing attack or network snooping attack, occurs when a malicious actor exploits an insecure network connection to steal data during communications.

Just as someone eavesdrops on a conversation between two people, network eavesdropping involves eavesdropping on conversations on network components, including servers, computers, smartphones, or other connected devices. Some even use popular gps blocker products to prevent eavesdropping.

How does a cyber-eavesdropping attack work

In a network eavesdropping attack, hackers look for weak connections between clients and servers: those that are unencrypted, use outdated devices or software, or have malicious software installed over the network. By exploiting these weak connections, hackers intercept packets passing through the network. Any network, web page, or email traffic that is not encrypted can be read by hackers.

Hackers often install sniffer programs. Security teams often use these legitimate applications, such as Wireshark, Snort, or tcpdump, to monitor and analyze network traffic to detect problems and vulnerabilities. However, these applications can also be used by malicious actors to find the same vulnerabilities and exploit them.

Unfortunately, detecting and preventing passive network eavesdropping attacks is extremely difficult, if not impossible, because the network is not compromised or modified. Active attacks are easier to detect, but usually the data has already been intercepted by the time a network change is noticed.

As with most things in security, prevention is better than cure. Here's an overview of the best ways to prevent cyber-eavesdropping attacks:

Block your phone

The most effective way to prevent eavesdropping is to close all the loopholes that have been opened for hacking. Wave jammers can interfere with the transmission of radio waves between cell phones and cell towers, which can interrupt the transmission process by generating large amounts of stray radio waves. When you turn on the wifi blocker, all phones, WiFi, and GPS stop working. However, the wave jammer interrupts all phone calls, which means normal calls are also blocked. So we have to be careful with these devices. You should consider installing a jammer in your office and turning it on during your most important meetings, because it does work.

  

Different countries choose different frequencies for mobile phone signal jammers

When you buy jammers, you should choose the signal jamming device according to the country you are in, because the signal frequency of each country is different, so the jammer you choose is also different. In this case, they can choose the signal jammer that suits them, because we know that there are different kinds of signal jammers, such as the EU version of the signal jammer and the US version of the signal jammer.

Now more and more people hope to obtain a signal blocker that can block signals in different frequency bands simultaneously or separately according to their needs. Now, in order to meet people's needs, more and more people have designed adjustable buttons and combined different jamming frequency bands together in one jammer to achieve their goals.

The best solution to get rid of GPS device tracking is a GPS jammer

Today, GPS tracking devices greatly assist people in orienting themselves. They play an important role in car navigation. They also help people find lost pets and cars. But at the same time, it annoys us that bad guys can learn someone's location through a GPS tracking device installed in a car.

To get rid of GPS device tracking, the best solution is a GPS jammers that blocks the GPS signal. They are designed to interfere with GPS navigation, tracking and data logging systems. GPS jammers can be used in cars, trucks, vehicles, homes or anywhere you think you are being tracked.

There is a wealth of information on the internet, and you can easily find out if your state allows you to use a GPS jammer.

Secondly, GPS jammers only prevent GPS devices from tracking vehicles, and have no effect on mobile phones.

No need to worry about whether your mobile phone can work normally in a car with a GPS jammer installed. Of course, some devices combine GPS jammers and cell phone jammer, which is why you should research that model before buying.

Third, the price of GPS jammers ranges from tens of fifty dollars to several thousand dollars. The price of a portable GPS jammer is only tens of dollars, while the price of a professional high-power remote-controlled GPS jammer can reach thousands of dollars. You should choose the one that meets your individual needs.

  

What is a radio jammer?

A jammer is a radio transmitter designed to interfere with, destroy, or block radio communication signals or services. In general, its role is to transmit a stronger signal than a useful signal on the target frequency band. Then the receiver no longer detects a useful signal.

Jammers often have a wider radius of action than people think or sellers suggest.

And, users are often overwhelmed by the range of devices, which are never limited to small Spaces, such as rooms or vehicles!

For example, a jammer used in a classroom to prevent students from using laptops could interfere with mobile phones in an entire community! Similarly, gps blocker used by employees who want to stop being geolocated by their employers may interfere with aircraft flying at 2,000 m or parked at 500 m. The use of jammers constitutes intentional and aggressive interference with the radio spectrum.

There are many types of jammers, depending on whether or not they can interfere:

Mobile phone and Internet: GSM, UMTS, LTE;

Other wireless transmission networks: wifi blocker, wireless LAN RLAN, WiMax;

Applications such as receiving geo-positioning signals from satellites (GPS, Galileo...) Cameras or wireless alarms...

A radio jammer usually takes the form of an electronic box with one or more small antennas, depending on the number of frequency bands it can interfere with. In the latter case, it is called multiband.

Telephone jammers: What are the applicable regulations?

The mention of the school phone ban at the start of the 2017 school year, and a few miscellaneous incidents such as GPS jammers blocking Nantes airport last April alerted us to the existence of these devices, making the rendering possible. Electronic communication equipment failed. If these materials exist, who can decide to implement them? Updates to applicable legislation.

Prohibition principle

Article L33-3-1 of the Postal and Electronic Communications Act prohibits the installation, possession and use of any equipment designed to render all types of electronic communications equipment incapable of transmission and reception.

Failure to comply with this ban is punishable by six months 'imprisonment and a fine of €30,000 (Article L39-1 of the Postal and Electronic Communications Act).

Immunity from sovereign prerogatives

Article L33-3 (2) of the Postal and Electronic Communications Act provides for derogations "for the purposes of public order, defence and national security or public judicial service".

As a result, France, the army, the General Directorate of External Security, and prison agencies are all authorized to possess and use jammers. According to a report by the National Assembly, deliberate interference is a sovereign prerogative.

The school has no plans for an extension

Installing "radio jammers" in schools has been proposed in a bid to crack down on the inappropriate use of mobile phone jammer during school hours. The State Administration of Education has reflected on the issue. It stresses that such devices are not selective, that it would also involve teachers, and that in the event of an emergency (attack, etc.), it would limit communication with the outside world.

From a strictly legal point of view, the 2012 ministerial response recalls the prohibition of Article L.33-3-1 of the Postal and Electronic Communications Act and the fact that such use is permitted by way of derogation "for the needs of the public." Order, defence and national security, or judicial public service ". They are not allowed to be used in schools because they are not mentioned in the Restricted Derogation list.

Specific and time-limited exemptions for performance halls

The 2011 Act introducing the ban came into force on 1 February 2012. However, according to Article 57 of the Act, radio installations installed in performance halls can render all types of mobile phones inoperable (transmission and reception). The date of publication of the decree may be retained for five years. Problems with the use of mobile phones in concert halls emerged in the 1990s, and jamming signal technology was effective for a time. That five-year period, which has now expired, was designed to allow theater owners to unload equipment.

From now on, there are other forms of regulation (messaging, self-regulation, etc.). Moreover, on the contrary, the use of mobile phones must not be prevented, including on these premises, because of terrorist threats.

  

Why use cell phone jammers?

You know why a lot of people use cell phone blockers? In fact, there are many situations that may require a cell phone blocker.

When you hear about cell phone jammers with spy GPS trackers, it's clear that you have some negative impressions about using such devices.

After all, you want to know if cutting off communication with a cell phone user is malicious.

However, the use of cell phone signal blockers is important for a variety of reasons. This depends on a variety of parameters.

School

Schools and universities are particularly useful places to use phone jammer. This is because blocking mobile phone signals can prevent students from being distracted by mobile phones.

In addition, students cannot cheat by sending cheating text messages to each other during the exam.

When it comes to facilities and surveillance systems, check out our range of top surveillance cameras. We have all types and models of surveillance cameras, whether for personal homes, schools or even shopping malls.

You can also choose between a hidden spy camera or a standard surveillance camera. Therefore, please make your choice according to your needs, as our primary goal is your safety.

High security site

This is the case in certain specific places such as prisons and detention centres. The use of telephone jammers in these places can prevent illegal communications between prisoners and visitors.

Of course, it's also useful to use cell phone jammers in places like movie theaters or libraries.

In these venues, customers want to enjoy their activities in peace. These are the only places where using a phone jammer would be useful.

Is it legal to use phone jammers?

In fact, the signal jammers is not meant to cause harm. In fact, even if the mobile phone signal is blocked, the frequency of GSM alarm emergency services will not be interfered with.

So feel free to use this device to give yourself and your customers the peace and quiet they deserve. Interference also allows the people inside your building or site to enjoy peace and security.

What should I consider when choosing the right model?

Admit that sitting on the bus listening to someone talking loudly about a problem on the phone is pretty boring.

It's even worse if it happens in the middle of an important meeting, or even during a fancy dinner at a restaurant. These are the most common reasons people buy different phone jammers.

There's only one thing you need to be aware of! If you're not sure how to choose the right type of signal blocker, then you'd better read the following information.

Your budget

The first thing you need to do is determine your budget. It's important to set the number and start searching for the devices in it.

Once you find a wifi blocker that suits your needs, you should start looking at reviews about it. Since the Internet is a great place, you can be sure that there are many people who have the same equipment and can share their experiences with you.

On our website, you will be dazzled by the choice between different quality models and the number of antennas (from 1 to 12).

Broadcast frequency

Keep in mind that different devices (such as GSM wireless alarms) operate on different frequencies. This is why one of the most important things is to understand the broadcast frequencies of mobile operators.

Support frequency

Once you have found the broadcast frequency, you can go to the next step to see what frequencies your device supports. If the product you search for is supported, then you can buy it.

  

Cell Phones: Buying a Jammer - You Have to Consider This

Jammers interrupt mobile device wireless connections such as WiFi and GPS. You can read what it's for and what to consider when buying one here.

What can cell phone jammers be used for?

cell phone jammer, also known as cell phone blockers or jammers, are devices that disrupt radio connections such as cell phone networks, WLAN or GPS by emitting radio waves. The range is between 10 and 40 meters.

The military and government even have models that can jam radio signals for miles.

Retailers can use gps blocker to prevent you from comparing prices in-store. Thus, retailers can increase sales.

Jammers are also useful in certain rooms where silence or distraction is desired. This prevents the phone from ringing while watching a movie or while young people are chatting at school.

But criminals can also use gsm jammer to disrupt wireless alarm systems and other radio communications, and prevent emergency calls from being made over cellphone networks.

Are cell phone jammers allowed?

The use and trade of such mobile phone blockers is prohibited within the European Union. Use may be fined up to 1000 EUR. Penalties could be higher if emergency calls are blocked buy jammers. In some European countries, jammers are approved by the authorities. Such equipment is occasionally used in French cinemas and theaters. But in Germany, this is strictly regulated: whoever wants to use radio frequencies needs to be assigned according to the Telecommunications Act. Even the import of such equipment is prohibited and strictly controlled. The devices are then confiscated and hefty fines imposed.

Use of mobile phone jammers

School cell phone jammer

The questions on the exam are well known. Use of unauthorized assistive devices such as cell phones, smartphones, tablets, wearables, or similar devices during an exam will be considered attempted cheating.

For some time now, auditors have increasingly observed remediation through the use of so-called cell phone jammers.

Products now available range from pure "cell phone indicators" to active jammers to smart IMSI catchers that force replacement of new GSM cells and log personal data in wireless network areas.

The Ministry of Education of Baden-Württemberg has issued a statement in this regard, clearly regulating the use of such devices:

From the Ministry of Culture's point of view, the use of devices that completely block reception by mobile phones by emitting their own radio waves ("blockers") is legally unacceptable, regardless of data protection checks. Because in the GSM frequency range only mobile network operators have the right to use the frequencies they auction and therefore also have the right to operate cell phone blockers.

The operation of mobile phone interceptors by third parties is an unallocated frequency use, which is prohibited according to Art. 149 (1) Art. 10 TKG. The use of mobile phone interceptors does not require a frequency assignment only if "the authorities exercise their legal authority in accordance with the conditions of use of the frequencies laid down by the Federal Network Agency". There is not sufficient legal basis for use in a school setting.

It is also illegal to use equipment that listens to or records messages and is punishable by breach of telecommunications secrecy.

From the perspective of the Ministry of Education, the use of a device that scans a specific frequency range and only shows that there are switched on phones in the room without identifying the exact location is permitted under data protection law, as no personal data has been processed.

The question, however, is whether it is wise or useful to use such a device, and therefore necessary. Carrying a mobile phone is already considered cheating in public school exams in Baden-Württemberg due to the special regulations that apply. Since the effects of such devices are easily circumvented, for example by placing a mobile phone in airplane mode, scanners are of no use in exam situations. In this case, the device would not be detected by the frequency meter; but would still be carried illegally, thus constituting a fraudulent act.

  

Jammers, also known as frequency interceptors, are a series of devices and services designed to protect individuals' inalienable privacy and security rights.

As you can clearly see, we only provide first-class cellular interference devices and provide excellent customer service from inquiry to purchase and use.

With our experience in this field, we know how to guide customers in selecting signal jammers that meet their needs. Perfectjammer also sells customized interference devices. We are honored to help you "carefully select" the most suitable phone jammer for your needs among the first-class devices sold in our online store.

Due to the continuous development of wireless technology, it is everyone's responsibility to use our professional equipment to help maintain silence in areas where quiet behavior is needed. What is a mobile phone jammer? Nowadays, mobile phones have had a huge impact on everyone on this planet. They are considered a large-scale and popular communication method used by over a billion people worldwide. The popularity of mobile phones and smartphones not only brings advantages, but also disadvantages for those who use these devices. That's why we firmly believe that almost everyone should have a mobile phone jammer, which is an essential small tool in daily life.

The mobile phone jammer is essentially described as a device that interferes with the mobile phone network, preventing communication between the phone and its nearby mobile phone signal tower/base station. Once the phone enters its interference range, the phone blocking device will interfere with its signal by emitting higher and stronger frequencies, causing the phone to enter a "blind spot". Due to the complete disappearance of mobile phone signals, users will be unable to answer or make calls.

When we talk about mobile phones, we also refer to the new generation of smartphones that are already equipped with 3G and 4G LTE/5G technology. People may use them for VoIP calls through WhatsApp, Viber, Messenger, and more.

Now that we understand what mobile phone blockers are, we need to understand why they are essential. Why do I need a phone blocker? Commuters on trains and buses have become increasingly impolite and rude. They believe that they can act as they please without having to bear the consequences. Okay, use a gsm jammer to shut them up. They will lose their way and look around, trying to find out why their phones do not have a signal bar. Perhaps this is the price they pay to speak loudly on the bus and annoy other early morning commuters.

In summary, this is the basic purpose of the mobile signal blocker we sell, which must be implemented in places of worship for religious gatherings, such as mosques, churches, synagogues, temples, etc. Theaters, restaurants, workplaces, and most importantly classrooms. It goes without saying that every teenager now has the latest smartphones, which can disrupt classes and disturb other students, let alone cheat in exams.

In addition, governments around the world are currently considering the idea of installing such devices in prisons and other sensitive government areas.

Please always remember to use interfering devices with caution. Although being forced to listen to strangers chattering on the phone while on the bus may be annoying, a little consideration can still be very helpful. Explanation of interference range and output power: First of all, let's say that the stronger the mobile phone signal in a place, the smaller the working range of the interference device. Therefore, it is recommended to check the reception of the phone in the area where the jammer needs to cause interference beforehand. This will determine the output power of the jammer you need.

The basic thing you need to understand about frequency interceptors is that they do not magically work according to the specifications mentioned, and will create a "dead zone" around them wherever you place them. They don't work this way.

The three main factors that determine successful installation are output power, antenna type, and cooling system.

Although the mobile signal in a certain location is strong, all three factors can have a significant impact on its interference range, overall performance, and durability. For example, the performance of a signal interceptor with a total power of 8W is not as good as that of a device with a total output power of 15W. Directional antennas provide a wider interference radius because they concentrate all output power in one direction, while omnidirectional antennas provide a 360 ° coverage range, resulting in a narrower range. Although each meter is important, the impact is not significant. In addition, advanced cooling fans can prevent the jammer from overheating, resulting in a longer performance and service life of the jammer gps.

In short, only after considering all the above factors can you choose the signal interceptor that best suits your needs. Always remember the following points: the higher the wattage, the wider the interference range.

  

Mobile signal jammer and Mobile Network Interceptor

The Invention of Mobile Phones

Mobile phones have become the most famous invention of the 20th century after penicillin, evolving into cameras, mini computers, etc., making them irreplaceable for every modern person. However, mobile devices have a drawback - they emit sounds and ringtones, so negotiations may not be successful - both parties cannot focus on the topic - they are always distracted.

The solution to this problem is to use mobile signal jammer. For a long time, they have been actively used by special forces, large theaters, concert halls, and multiple companies. Now, these signal scramblers are also sold globally. Our company provides customers with devices that can "protect" their phones: compact phone silencers and fixed jammers with a range of 8-15 meters. With the help of electronic device jammers, you can truly speak calmly without worrying, without being distracted by inappropriate calls, or worrying about being eavesdropped, because even if the phone owner is unaware, the phone can become an excellent listening device. From the perspective of tactical capabilities, mobile phones have acquired the attributes of covert information retrieval tools - namely "legitimate eavesdroppers". It is worth noting that mobile phones have the most unique tactical capabilities.

Warning!

Many European countries prohibit sales within the EU. Before continuing with the information request, please check the current regulations in your region. For law enforcement use only - as needed.

If you want to purchase a jammer, then you have come to the right place. On our portal, you can purchase various interceptor samples for mobile phones, Wi Fi, and GPS/GLONASS. We will supply goods to other countries around the world. Purchasing a signal silencer from the perfectjammer store is both simple and suitable.

The working principle of a telephone jammer

There are various ways in which telephone jammers work. The simplest is the Faraday cage, which does not require special costs for production. A unique panel is installed on the wall to passively block signals. There is another device - a mobile phone jammer, which can detect the presence of available phones within a certain radius. Once a call attempt is detected, the phone signal will be blocked. Therefore, radio jammers can also interfere with incoming calls. In this case, the phone will enter standby mode.

You can purchase portable phones and effective fixed silencers from our online store. The frequency jammer operates using radio signals; If the detector records a signal

We have become very dependent on global positioning. A power outage will cost us billions of dollars. And there is no backup yet.

The dire threat of GPS could cripple corporate America

A growing problem for GPS: There is no backup system in the United States. Most of our critical infrastructure, including power grids, banks, transportation systems, and telecommunications networks, relies on GPS. In addition to traffic maps and other positioning services, GPS is used for high-precision timing required for high-speed financial transactions, wireless network synchronization, and grid synchronization. But the rising risk of severe blackouts has gone largely unnoticed. "I don't think GPS vulnerabilities have gotten a lot of attention because, unlike cybersecurity, there haven't been any major disasters," said Marc Weiss, a fellow at the National Institute of Standards and Technology.

GPS and other timing systems will become even more important to modern life in the future. With the rise of connected sensors, devices and machines (i.e. the Internet of Things), timing signals need to be more precise. A government report last year concluded that a lack of high-precision timekeeping systems could hinder the development of new technologies, such as instantaneous collision avoidance systems in cars or communication links in smart grids.

The United States is at greater risk than countries such as Russia, China, Iran, Saudi Arabia and the United Kingdom, all of which have some form of ground backup. GPS outages happen from time to time because the signal is weak and highly susceptible to interference. "Terrorists can just use a GPS jammers to carry out an attack," Goldward said. Each jammer costs less than $50 and is extremely difficult to track and stop. Note that companies such as Spirent UK provide equipment to assist in the detection of GPS interference to help combat such interference.

The Global Positioning System provides navigation for our ships at sea. It is at the heart of the new next-generation air traffic control system. It can even time-stamp the millions of financial transactions that take place around the world every day.

GPS faces threats from terrorists, rogue states and $50 cell phone jammer

• Criminals, terrorist groups and rogue states, even those with a basic GPS jammer you can buy for $50 on the Internet, face extreme challenges, said Todd Humphreys, a GPS expert at the University of Texas. big risk.


• "If you were a rogue state, or a terrorist network, and you wanted to cause some massive damage — maybe not an explosion, but an economic attack on the United States — that's what you might do." As a weakness," he told Fox News.


• Humphreys was the keynote speaker at the UK ICT Knowledge Transfer Network's World Experts Conference in London. His predictions about the prospects for this emerging threat are dire.

In 2010, for example, British researchers aimed a low-altitude GPS signal jammers at a test ship in the English Channel. The results were shocking: the ship went off course without the knowledge of the crew. Passing false information about their location to other ships increases the likelihood of a collision. The communications system stopped working, meaning the crew could not contact the Coast Guard. The emergency services system used to guide rescuers is completely out of order.

1. Then there's the disappearance of a U.S. drone over Iran. Humphreys believes Iranian authorities confuse the ultra-sophisticated RQ-170 spy drone into landing mode by using simple jamming techniques. The drone's Achilles' heel? It has a civilian GPS system, not a military-grade encrypted model. It doesn't take much to blind it and force it down.




2. Another threat that is burgeoning is so-called "spoofing." Unlike gsm jammer, which block or scramble GPS signals, "spoofers" mimic information from satellites. It can fool an aircraft, ship, or other GPS-guided device into thinking it's somewhere, but it's not.




3. Organized crime is already trying to exploit this possibility, Humphreys said. A criminal gang may hijack a container truck full of high-value cargo and trick the owner into thinking the truck is heading to a predetermined delivery point instead of the gang's warehouse.




4. Hanvers: "Civilian GPS signals are completely open and vulnerable to spoofing attacks because they have no authentication and no encryption. It is almost trivial to imitate these signals and trick a GPS receiver to track your signal." Authentic ."



5. Hijacking a container is one thing. Deceiving the global financial system is another matter. Another emerging GPS threat, Humphreys warned in a speech in London, is global stock and commodity trading networks.

Every transaction is time-stamped using a GPS clock. Computer programs monitor these timestamps with millisecond precision. If something goes wrong, many projects will be taken off the market. Hackers could easily interfere with these timestamps, triggering trading procedures, causing sudden liquidity crises and potentially mini-market crashes, Humphreys said.

Manipulating time, then, pays high dividends. An unscrupulous trader or criminal organization can make millions of dollars by delaying time even by a fraction of a second.

"You're able to match prices between networks in a different way than anyone else in the world," Humphreys said. “Everyone else in the world might be off by 20 milliseconds, and you happen to know the actual time. So you can buy low in one market and sell high in another.”

These devices are illegal in the US, but can be easily obtained on the Internet for as little as $50. People use them to avoid tolls, to hide from the prying eyes of their spouses, or to use company vehicles for unintended purposes. This sometimes has unintended consequences.

Devices that interfere with GPS may actually have a legitimate purpose: to protect individual privacy, he said.

"People have a right to privacy in their own lives," he said. “However, having a small dot-sized GPS tracking device to be able to secretly locate them at your friends — they would want to resort to some kind of jamming or deception to defend against this invasion of privacy.”
