From ancient times to today, security has always been an important aspect, such as military, network and many other fields. In this case, we need to use different types of security tools in different areas, such as WiFi jammers, which can protect the network security.

In order to ensure a safe environment, various safety measures have been taken in different locations and regions. For example, in factories, hotels, schools, and many other places, we can usually see that in many places, maintenance personnel of buildings should register first. All of this is to ensure security. We can see that security plays an important role in different regions and networks. Now, more and more people are accepting wireless network jammer devices.

You can use a recording blocker to prevent recording during important meetings!

The most effective means to prevent recording is to generate random noise signals through the recording masker, which can suppress the voice signal, so that the recording equipment picks up only noise information, but cannot distinguish the voice information and cannot restore it from the recorded signal. The original information is output to ensure the security of voice information. The recording blocker adopts security encryption processing, and effectively prevents post-restoration by mixing high and low frequency audio sources.

Jammer-mart has focused on information security for 14 years. The newly developed L7B recording jammer has been upgraded on the basis of the original equipment. The FPGA-based ultrasonic noise algorithm eliminates the high frequency noise of the old equipment. It has joined the brands that have been on the market in the past two years. The information of mobile phones and recording devices has a very obvious effect on new recording devices and mobile phone recording. It is suitable for confidential meeting rooms, public security bureau petition centers, procuratorate reception halls, courts, negotiation rooms, offices and other places for private conversations.

The recording blocker is completely silent when working. The sound recorded by ultrasonic recording and eavesdropping equipment is completely noisy, and no meaningful information can be extracted. Designed with the appearance of ordinary audio. Confidential meeting room, public security bureau petition center, prosecutor’s office reception hall, courtroom, negotiation room, office and other places for private conversation.

Working principle: The recording jammer emits ultrasonic waves with random noise that cannot be perceived by human ears. When digital devices such as mobile phones are recording, these noises are recorded into the digital device together with the sound of normal conversation, making the recorded audio invalid. The audio information in the captured video also has the same interference effect. Because the noisy ultrasonic noise is randomly generated and cannot be restored, the audio after the interference cannot be restored, thus ensuring that the original information is not leaked and spread.

As a new product, recording jammers have received more and more attention and support from people. From the previous government agencies (mainly the public security system and service-oriented windows) to the current enterprises, the needs of enterprises have gradually increased. An important reminder for us. It shows that business people are gradually attaching importance to the safety of voice information and their awareness of self-protection has increased. Imagine if in a conversation scene, if any participant turns on the recording device, or connects the call and keeps it in the call state, the remote personnel can There is no security to hear the content of the conversation at will. In this case, the recording blocker can play a good role in protecting the security of audio information.

Cell phone jammers installed in Paris Health Prison

The Paris establishment, which has been closed for several years, is now “opening” its doors again and is now equipped with a new system of cell phone jammer, with fixed telephones installed in the cells.

Inaugurated in 1867, the 2.8 hectare health prison in the heart of the 14th arrondissement of Paris had become the most blatant symbol of the decay of French prisons over the years.

Camouflage handheld phone jammer

Healthcare, closed for several years for work, is reopening today by incorporating an important technological development at the prison universe level that, if it worked, could be used in other facilities.

In 2017, 40,067 phones and accessories were confiscated from the 70,000 inmates in 180 French prisons.

In addition, the government stated that the disruptive systems were largely ineffective.

During the renovation of the health prison in Paris, the authorities decided to develop and maintain a brand new jamming system for mobile phones for six people for the French company SAGI.fr.

At the same time, landline phones are now installed in the cells.

Telio, one of the leading European companies in this sector, has been granted a public-law license for landline telephony for ten years, reports the AFP.

“Access to the landline phone in the cell is an appeal to the detention center.

Detainees can call their families without restriction, “said the director of the institution, Christelle Rotach, quoted by the AFP.

Prisoners can only call pre-approved numbers.

No telephone will be installed in the isolation or disciplinary rooms.

In the case of landline telephones, Telio finances the entire investment and is compensated for by the price of calls paid by prisoners.

The cost of calling a landline is 0.08 euros per minute and 0.18 euros for a mobile phone on mainland France.

GIDAS’s real-time interference detection makes the navigation system safer

It is estimated that there are currently the same number of navigation receivers on Earth as humans. Positions, navigation and time signals from space-based constellations such as Galileo and GPS form an invisible, indispensable infrastructure that lays the foundation for many modern aspects of modern life (communication, energy, and transportation).

Satellite navigation is helping to control more and more planes, ships, trains and self-driving cars. At the same time, navigation-based time stamps can mark real financial transactions worth billions of euros and coordinate the synchronization of the grid. Satellite navigation is always active and available anywhere on the planet. Therefore, it is easy to take usability for granted. These signals from space are equally important, and they are also susceptible to ground interference.

Andreas Lesch of OHB Digital Solutions in Austria said: “It’s just a matter of output power.” “The navigation signal on the ground corresponds to the light of the 60-watt lamp on the satellite. For Galileo, its distance in space is about 23,222 kilometers. These weaker signals may be accidentally or deliberately destroyed by stronger local radio signals or even misleading false navigation signals (so-called deception).”

“We have developed a new GNSS interference detection and analysis system, GIDAS, to protect critical infrastructure from damage or deception by continuously monitoring important signal frequency bands. In this way, GIDAS can trigger alarms in real time, determine the nature of the failure, and then determine the cause of the failure. The location of those dangerous portable devices so that the authorities can take immediate remedial measures.”

Although at least three stations are required to locate interference sources connected to the entire monitoring center, GIDAS can provide interference detection and orientation through a single reporting station. Monitoring centers can also be connected to each other, which makes the GIDAS system easy to expand, from ensuring a single port, airport or key location of the system to the entire city or region.

“People are only catching up with the severity of this problem now,” Andreas added. “In parts of Europe, the highest density surveys show about three to four signal jammers per hour.

These small devices are technically illegal, but can be purchased online for a few hundred dollars or less, and are usually sold as data protection devices. The sales range of the jammer is only a few meters, but the actual use range may reach tens of meters or more, which may cause unnecessary widespread interference. For example, the famous American truck driver takes the jammer while sailing at Newark Airport as long as he passes. Will shut down the system.

Could the police actually shut down a city’s cellular service?

At around 1 am on Monday, a strange tweet claimed that Washington, DC had been disconnected from the digital world. The Washington Post later reported that the Twitter accounts of only three followers were the first to report a suspected interruption. When people wake up and register online, #DCblackout is all the rage in the United States. The hashtag appeared in thousands of tweets, accompanied by reports of explosions, missing protesters and silencers of police rifles. What followed was a brief online chaos: Did the police really block the cell phone tower? What should the so-called failure cover? The local reporter quickly tweeted that they had not experienced any failures, and later that day, the rumors were thoroughly debunked. It turns out that a power outage is the highest level of error message. This also dispersed the interference of local protests. The local police used violent methods against the protesters all night, including pepper spray, rubber bullets and tear gas.

However, the prerequisite for the power outage is that the police (or the federal government) can completely shut down the communication network-this behavior has seriously affected the freedom of speech and assembly rights, as well as the safety of protesters and passersby. Although it did not happen on Monday, the joke raised the question of whether it is possible for law enforcement agencies to cause technical and legal power outages.

Americans tend to view deliberate service interruption as a dangerous strategy used by oppressive regimes abroad. In a speech by the American Civil Liberties Union, Jay Stanley, a senior political analyst for the Privacy and Technology Project, told me that interruptions in communication are often seen as “a terrible form of abuse” and are used worldwide to cover up repression of sexual violence and other violations. Human rights behavior. ”

But this form of censorship has occurred at least once in the United States. In 2011, the Bay Area Rapid Transit System (BART) suspended cell phone service at a subway station in downtown San Francisco after hearing about plans to protest the BART police’s plan to kill a man. The purpose of BART is to prevent protesters from coordinating, but it is short-sighted, thus making the agency the center of freedom of speech controversy across the country. The Federal Communications Commission intervened, and BART’s actions were condemned by human rights organizations such as the Electronic Frontier Foundation (the incident was called the “BART La Mubarak in San Francisco” incident). The FCC investigated BART, but like Harold Feld, the senior vice president of non-profit public knowledge told me that the committee decided not to make a declarative decision on the incident. This boils down to a technical problem: BART actually shuts down the service by shutting down the equipment in the underground system instead of destroying the signal.

No similar incidents have been confirmed since, but in the 2016 Tateishi protests, Wired reported that tribal leaders believed that the police had blocked their phones. The problem with proving these claims is that it is difficult to determine whether malicious behavior is occurring or just a bad signal. Only agencies like the FCC have not yet investigated the claims to truly verify the occurrence of traffic congestion.

The BART controversy and, to a lesser extent, the Standing Rock controversy, both show how complicated the shutdown signal can be in the United States-and how we truly fail to understand and resolve the blueprint for current and future law enforcement blackouts. What we do know is that almost ten years later, it is still possible from a technical point of view. According to Joshua M. Pearce, a professor of materials science and engineering at the Michigan Technological Institute, there are two ways to cause ground blackouts. (Turning off BART is an unusual situation because the authorities can access the device themselves.) The first is to ask (or require) the service provider to shut down a specific set of cell phone towers. It’s as simple as flipping a switch

The second method (and the more difficult method) is to use jamming technology, which sometimes sends false signals, overwhelming the signal from the cell phone tower. Small short-range equipment can be purchased abroad (for example, equipment used by some overseas universities to stop fraud, which led to the suspension of a high school teacher in Florida in 2015). In theory, you can use a large number of such small devices to call neighbors, but this is not convenient. Pearce believes that signal jammer have greater coverage, but only organizations like the National Security Agency own them.

Surveillance technology is more advanced than you think

Spurred on by the well-known terrorist attacks of September 11, 2001, modern surveillance has become an even more important method of protecting people from possible acts of terrorism or of eliminating acts of dissident. And there is no shortage of companies willing to provide the mechanism that can safely do these tasks.

Some of these tech companies have tools that allow governments to easily break into individuals’ phones and PCs, as well as powerful electronic eavesdropping devices that can be used to record all active Internet communications across the Wallstreet Journal. Those papers, more than 200 pages from 36 different organizations, were obtained by people who attended the secret security conference held last month.

Many of these technologies presented at the conference are related to monitoring large amounts of information. A company has selected tens of thousands of synchronous calls from landline and mobile networks or intercepted them en masse. The other describes how she helped the leading Chinese cellular operator monitor the Internet content and apps on the country’s cell phones in real time.

The annual retail market for surveillance tools has expanded from almost nothing in 2001 to a total of $ 35 billion this year, the Journal reported, citing information from TeleStrategies, the conference operator. Organizations operating in this sector argue that their goods are designed to catch criminals and are only made for sale to government and law enforcement agencies.

Still, some international companies are finding that their recent business activity has given them unwanted attention. Cisco Systems is feeling the nasty aftermath of the lawsuit filed earlier this year that accused the tech company of providing and supporting a huge surveillance system that enabled Chinese authorities to easily track and censor all internet activity of a spiritual group . Cisco officials denied all charges, claiming that Cisco sells the same legal equipment in China that it sells in other countries around the world in compliance with US government regulations and laws.

As you can see, if Cisco sells the same equipment around the world, US citizens may face the same risk as Chinese people. In fact we already are. So protect yourself by using wireless wifi jammer and make sure that nobody is watching you. And of course your comments are welcome here!

The type and working principle of signal shielding instrument

Recently, frequency jammers have appeared in the automotive and telephone markets. These small devices are used to encode and redirect the frequencies of the waves emitted by an electronic device, either in order not to interfere with certain professions or to serve less available destinations.

The different frequency jammers

There are different types of frequency jammer. More and more theaters and hospitals are using it. Frequency jammers prevent cell phones from receiving waves and receiving and making calls or messages. If this is a means of gaining artist respect for function rooms, it can be vital for hospitals as certain waves distort the results obtained with diagnostic or monitoring tools such as electrocardiograms.

Some motorists also equip their vehicles with frequency jammers so that they are not detected by the police or gendarmerie if the speed limit is exceeded. This is prohibited by law and, if verified, could result in law enforcement and a hefty fine. Frequency jammers are also popular with car thieves, who thus interfere with the frequency of your remote shutdown. They think you have closed your doors and you don’t. The thief does not have to get into the vehicle until you have turned your back.

How do frequency jammers work?

A frequency jammer is not a device that takes up a lot of space because it fits in your hand. However, it is a technological tool. It’s inexpensive but not commercially available. The internet and the black market are the main suppliers of frequency jammers.

These pick up waves with an antenna and encrypt them, i.e. they make them illegible. Some frequency jammers have a long range, but the basic models don’t exceed 40 meters.

Why should public WIFI will be used to lose personal information?

Mass users and fragmented internet habits make public WiFi a mandatory requirement in the mobile age. Thanks to this feature, the WiFi Universal Key, which provides a free network service, has been introduced with 900 million users for four years. Google and Facebook have launched similar services in several regions.

In recent years, however, the media have repeatedly reported theft of user accounts caused by the use of public WiFi. The public has had tremendous fears about the security of the public WiFi: whether the public WiFi is being used, it can lead to the disclosure of personal information and even damage to property?

How did your personal data come out? Maybe you drink coffee, use free wifi and then personal information is stolen. In recent years, free public WiFi has become a hidden danger for citizens to divulge personal information and compromise network security. Therefore, WLAN management in public places has come into focus. Corresponding countermeasures are also currently being investigated.

Hackers set a camouflage WiFi, a parasite highlight of the signal is very strong, can suppress the coverage of the normal radio signal, set up a cell phone and network dialog between the listening level in the users and the operation of the first one, which passes on your disguise WiFi then , in the WLAN network, your personal data is in a state without data protection. This means that everything you do on your phone can be viewed.

How does the hacker transfer your money over WiFi?

Step 1: The hackers set up free WiFi to allow the victim to access the mobile phone.

Step 2: When disguising the website, write down the password of the victim’s login to the phishing website and personal information.

Step 3: steal user information and steal the victim’s bank card number password.

Step 4: Install victim mobile trojan virus and block user SMS.

Step 5: Use trojan virus to steal cell phone payment verification code and complete the theft.

How do you protect your network security?

First of all, do not connect the unknown wireless network, online shopping, payment and other sensitive operations. It is recommended not to use public WiFi.

Second, the cell phone, computer and other electronic products to kill viruses, install security software, and change the password frequently to maintain security.

Third, using a wifi jammer can effectively avoid automatic access to unknown WIFI, which can prevent your smart device from being attacked.

Fourth, the person’s confidential information must be properly kept, not in email, chat tools, and other places where account password information is revealed. Different websites and systems suggest using different accounts or passwords.

Detection of GPS interference technologies against autonomous vehicles with cost-effective solutions

As consumer drones become more accessible and capable, as well as new opportunities, so too do concerns about potential security threats. Consumer drones can be purchased almost anywhere these days at an affordable cost and are widely used due to their ease of use and low cost. However, they also pose significant risk to organizations in key sectors, and the news that these drones are being used for surveillance and other malicious purposes is nothing new. Fortunately, as technology advances, various ways have been developed to counter such drones and detect them from system to system via audio, radar, etc. depending on the system.

Wireless technology plays a vital role in controlling unregistered UAVs to keep businesses safe and secure. Rajant Corp’s DX-1 Development Kit is one such technology – it is a small, lightweight radio with antennas that offers strong multi-frequency encryption options for high-performance use. The company is also testing detection technologies for other video, radar and sonar devices.

Similarly, the Infinidome GPSdome is the world’s first non-military GPS anti-jammer technology to be commercially available and used across the critical infrastructure space. The Israel-based wireless security company develops solutions to detect and secure the wireless communication of various autonomous vehicles. At the beginning of January, it received bridge funding from the European AI fund Boundary Holding, whose investment is intended to help the security company advance its path into mobility technology. With Infinidome already earning over $ 1 million, funding from Rajat Khare-founded company will hopefully further boost Infinidome to move towards autonomous technology and gain a head start in the marketplace.

The use of drones has shifted dramatically in recent times – from entertainment to commercial purposes. As a result, such reliable solutions to detect and combat potential threats have become the order of the day.

UAV jammer have become the most effective solution to the threat of UAVs. It can make the drone lose signal control and slowly land to the ground.

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.
