How smart home products steal your secrets

There is no doubt that the US’s information technology strength is in an absolute leading position in the world. This strength is not only reflected in the number of information technology talents, but also in the ability to research and develop information technology, control of information resources, and influence on the formulation of information technology standards. For example, the world’s largest professional network warfare unit is in the United States; the mainstream operating systems (such as Windows, MacOS, Andriod, etc.) installed and used in the world’s computers and smart terminals are all developed and designed by the United States; the world’s main 13 root domain name servers Ten of them are in the United States…It is no exaggeration to say that the United States has the power to monopolize the world in terms of information technology. Of course, this also includes the power to invade and monitor the world.

In addition to operating systems, smartphones, tablets, web cameras and other software and hardware that are often “visited” by hackers, household products such as routers, set-top boxes, smart cars, and even smart TVs, smart air conditioners, etc. cannot escape the fate of being invaded and monitored by the CIA . Take smart air conditioners as an example. In order to improve the user experience, some manufacturers have installed microphones inside the air conditioners to collect and feedback the noise generated during the operation of the air conditioners, and use this as a basis to improve the process to improve the user experience. The CIA can use its exclusive mining (not publicly disclosed or feedback to related manufacturers) or vulnerabilities that have been disclosed but not patched in time (such as zero-day vulnerabilities) to attack smart air conditioners and ultimately gain control. Once the intrusion is successful, the microphone used to collect the operating noise of the air conditioner becomes an eavesdropper that monitors the sound of the surrounding environment, making it impossible to guard against. For another example, by invading and controlling smart cars, the CIA can tailor “traffic accidents” for some key targets, which are silent and difficult to track down. The most frightening thing is that the malware developed by the CIA can bypass software that uses cryptographic technology to encrypt storage and communication, and directly obtain your communication information. It should be noted that the “bypass” here does not directly crack the data that has been encrypted by the application, but has been monitored and acquired at the beginning of the information collection and entry (not yet encrypted). Of course, if your smart terminal uses point-to-point encrypted communication at all times, the CIA will still be unable to receive the monitored information.

So you still need to know about mobile phone signal jammer, Jammer-mart.com will be your good choice.

Detailed introduction of mobile communication jammer

KZXJ-1D communication signal intelligent monitoring and cutting equipment is a series of electromagnetic interference products of Chengdu Anze’s national distributor, which can effectively shield CDMA, GSM, DCS, PHS, TD-SCDMA, WCDMA, CDMA2000, FDD-LTE in a certain place , TD-LTE, WIFI mobile phone signal and Bluetooth communication.

UAV jamming system contributes to national defense

In the Zhurihe military parade in Inner Mongolia on July 30, 2017, there was a modern information warfare unit, which was responsible for ensuring the communication of the unit. Drone jammer is another important part of modern information operations. Among them, the second-generation individual portable anti-UAV equipment is an anti-UAV information individual operation equipment.

This single-soldier drone jamming device interferes with the drone’s sensors and flight control signals to force the drone to land or return, without destroying the drone. The UAV jamming system of the device looks like a rifle, and it is easy to operate and can be operated by one person. It can block the signal between the interfered drone and the remote control by transmitting wifi and GNSS signals. When the jamming system is turned on, it will completely cut off the connection between the drone and the ground workstation, thereby ensuring airspace safety and interfering with illegal drone intrusion.

Military heavy ground needs UAV countermeasure system defense

With the development of science and technology, drones have become more and more common. They are not only used in the military, but also in civilians. Moreover, drones are widely used. They have night-time camera functions and can quietly disappear at night. Flight at various places. People can use it to take pictures, to video, to explore, to peep, etc. It depends on what kind of behavior the drone owner will have. If it is a military powerhouse, drone countermeasures systems are needed for defense.

Since drones are more common and common, if a military site is peeped or attacked by drones, it will bring serious consequences. Because the drone has an intelligent form, it can also be controlled. As long as the operator connects to the computer, he can see everything the drone sees through the computer, and some can also launch an attack. There are many military secrets in military powerhouses. Once snooped by drones, it often leads to the leakage of military secrets.

If there is a drone jammer in a military powerhouse, once the UAV enters, the surveillance system can be used for monitoring and the UAV can also be landed. Destroying devices can also be used, but generally as long as the drone is knocked down, it can be studied through the drone to know the main messenger behind the scenes.

Mobile phones bring safety hazards to gas stations

The number of small cars in Shenzhen is growing rapidly at a rate of 200 vehicles per day. How much do new drivers know about the safety regulations of gas stations? Yesterday, the reporter randomly interviewed several gas stations in the city and found that although the safety warning signs in the gas stations were very eye-catching, many drivers turned a deaf ear to the safety regulations such as banning mobile phones and turning off vehicles when refueling.

Most drivers have used their mobile phones at gas stations. How many people have complied with the safety rule of “turn off the vehicle when refueling”? The reporter interviewed several gas stations in the city and learned that 80% of novices often need to remind the fueler to stop the fuel when refueling. Old drivers generally do not need to remind the fuel to stop, but some old drivers do not want to stop the fuel because of trouble.

At the Sinopec gas station on Hongli Road, Ms. Huang from Meilin Village told reporters about her dangerous experience. Once when she refueled, she got out of the car without stalling, and the fueler reminded her to refuel after stalling the car. When she was refueling, her cell phone rang, and the fueler asked her to stand farther away to answer the phone. At that time, she felt a little unhappy in her heart, thinking that the fueler was very unkind. When she was standing far away on the phone, she suddenly heard a strange noise from the spray gun being refueling, and saw a sudden electric spark flashing from the front of the car. Although the spray gun automatically stopped refueling later, Ms. Huang was shocked. She told reporters that if it weren’t for the reminder of the fueler, it might have caused a catastrophe.

At a gas station near Liantang in Luohu District, 15 vehicles came to refuel within 20 minutes. Among them, 9 drivers were talking and laughing on their mobile phones while refueling. When the fueler was refueling a car, the driver’s mobile phone rang, and the driver picked up to answer the call. Although the fueler saw this scene, he did not remind the driver. On a pillar next to him, there was a post “No mobile phone use”. The striking goal.

During the reporter’s interview, two-thirds of drivers said they had used their mobile phones at gas stations, and many drivers even said they didn’t know this rule at all. A Mr. Zhu said: “I have never heard that calling on a mobile phone in a gas station will cause an explosion.” Many drivers think this is a big or small matter, and there is no need to make a fuss. Illegal operations can easily lead to accidents. It is common knowledge that fireworks are strictly prohibited at gas stations, but it is not clear to so many people that dialing or receiving mobile phones at oil depots or gas stations or refueling without turning off the flame may cause an oil and gas explosion. As more and more people use their mobile phones at gas stations and do not turn off the gas to refuel, relevant people warn that such illegal operations may become the fuse of an oil and gas explosion, and its danger is tantamount to playing with fire.

A person from the petrochemical company said that the density of oil and gas around the vehicle will increase sharply when refueling. At this time, the electronic friction generated by the mobile phone in the transmitting or receiving state may ignite the gasoline and cause an explosion. In fact, the manual of general mobile phone products will indicate: Do not use the mobile phone at the gas station! At the same time, the reporter learned that only last year, gas stations in Yueyang, Zhengzhou, Changsha, Lanzhou and other places had exploded due to the use of mobile phones, causing serious incidents of casualties.

Drones are causing trouble again

From 6 am to 6:30 am local time on May 14, Saudi Aramco’s pumping stations 8 and 9 were attacked by drones, and the company was forced to temporarily close the east-west pipelines. The Yanbu Port that was attacked this time was even more than 700 kilometers away from the Houthi armed forces’ control area, and the ASEF-1 small drones currently in the hands of the Houthi are simply not enough to support such a distance. Voyage. The only explanation is that the attack was caused by a Houthi-armed drone attack squad that penetrated the border between Yemen and Saudi Arabia and carried out a long-distance attack.

Affected by this incident, international oil prices rose sharply during the intraday session, and the intraday increase once exceeded 1.5%.

In March of this year, the Houthi UAV has publicly reached an important strategic goal in southern Saudi Arabia: Suqa Phase 2 of independent desalination and power plants. Compared with the last reconnaissance operation on Suqa Plant 2, the attack on Yanbu is even more shocking, which is too far away from Yemen. Yanbu is located in the central area of Saudi Arabia’s Red Sea coast. The closest distance to Yemen is more than 800 kilometers. The range of small drones in the hands of Husseis is not that far. For such a long-distance flight, at least a medium-sized drone of the level of Rainbow 3 is required. The flying distance has exceeded the direct communication distance between air and ground. Satellite relay communication equipment is required to ensure the communication between the drone and the ground station. Because of the Houthi armed forces’ equipment level and organizational capabilities, the take-off point for this attack cannot be in Yemen. Either take off from the sea, or secretly infiltrate and take off near Yanbu. Obviously the former is the least difficult to implement.

The seven UAVs used in the attack were QASEF-1 suicide UAVs in the hands of Hu Sai. The pictures and information of the aircraft that Hu Sai has shown to the outside world are based on Iran’s Ababil-2 UAV. The maximum flight distance can reach 150 kilometers, the length is 2.5 meters, and the wingspan is 3 meters. Small fishing boats can carry it. . It is very likely that the fishing boat controlled by Husai sailed concealedly to the sea off Yanbu Port. The 150-kilometer voyage can ensure that the ship is on the high seas. The total weight of the warhead carried by the 7 QASEF-1s is 210 kg, which is enough. Two carefully selected pumping stations caused serious damage.

This shows the touching degree of the combat power of the Saudi “Royal Army”. First of all, the borders of their homes were infiltrated by the armed men of the other side without even knowing it, and they were allowed to run hundreds of kilometers in their own territory. What’s more, Iran’s aid to the Houthi armed forces has been significantly reduced after the sanctions. This can be said to be a wave of high-profile UAV counterattacks by the Houthi armed forces against Saudi Arabia under desperate conditions. Saudi Arabia, whose annual military expenditure is as high as 67.6 billion U.S. dollars, has nothing to do with it!

It’s time to consider using drone jammer to counter drone.

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”.
