A year after Todd Humpreys and his research team tricked a drone with a jammer, a professor at the University of Texas at Austin led another team to remove the yacht from the canal. The $80 million private yacht uses the world's first recognized GPS spoofing device, a briefcase-sized piece of hardware built by Hamprice and his team.
"Before we conducted this experiment, I had no idea how possible it was to deceive a warship and how difficult it would be to detect such an attack," Humphreys said in a press release.
The experiment was carried out during a 213-foot yacht crossing the Mediterranean from Monaco to Greece. Two graduate students, Jahshan Bhatti and Ken Pesyna, used GPS jammers to broadcast bad GPS signals from the ship's deck to the antenna. Once the researchers secretly established a connection with the ship's GPS receiver, they were able to turn it off slightly. GPS tracking in the control room showed that despite the manoeuvre, the yacht was still travelling in a straight line.
A University of Texas yacht experiment has uncovered cybersecurity vulnerabilities in the maritime industry. These shortcomings are particularly important given the high cost of sea-going vessels and their outsized role in international trade.
"The ease with which Todd and his team can indeed take control of a million-dollar yacht is proof that we need to increase investment to ensure that our transportation system is protected from possible deception," Chandra said. Bart, director of the National Center for Transportation Research. University of Texas at Austin.
During an Autopilot(NOA) test drive, Regulus Cyber tricked a Tesla Model 3. NOA is a GNSS dependent feature that allows the high-tech Tesla Model 3 to make turns and lane changes without driver confirmation.
To fool the Model 3's automatic navigation system, the Regulus research team sent false satellite coordinates of the gsm jammer to an antenna mounted on the roof of the car. The fake coordinates correspond to a location 150 meters before the freeway exit. After receiving the spoofing signal, the Model 3 reacted almost immediately. It is believed the car was just 500 feet from the highway exit when it suddenly slowed down, turned on its right turn signal and turned toward the emergency exit. The driver was taken aback - by the time he grabbed the steering wheel, it was too late to correct the car's position and smoothly put it back on the highway.
The impact of drone jammers on the drone industry
Since safety is a top priority for civil aviation authorities worldwide, we must meet these safety requirements to integrate into national airspace. Therefore, ensuring aircraft safety is one of the main drivers of the drone industry. Safety involves parachutes, detection and evasion, and new remote identification rules. Increasingly troublesome, however, is how easy it is for consumers and bad actors to use relatively cheap and readily available drone jammers to interfere with navigation systems.
The so-called "clumsy, reckless, criminal" will cause a lot of man-made GPS interference.
For a few hundred dollars online, anyone can buy a GPS jammer that disables anything in its range of service, including your drone. Not all of these purchases are malicious, and some of them are simply the result of distrust or ignorance of the technology, but the result of individuals choosing to use the technology without realizing the consequences. Whether intentional or not, the loss of GPS reduces the time it takes to complete important missions and threatens the safety of people and property on the ground.
Ivan Stamatovski, Commercial Director at Easy Aviation, explains: "To give you an idea of how important GPS is for most drones. In fact, it is the only way for them to understand their location and environment. Drone news. "There is no such thing. They are practically blind."
While some drones can operate in environments where GPS can't pick them up, most rely on GPS to maintain operational control. In addition to the obvious safety risks posed by out-of-control drones, which can lead to accidents, important tactical missions can also be derailed at critical moments, resulting in loss of situational awareness, loss of valuable data, and even loss of life. This is a particularly pressing issue for companies like Easy Aero, which specializes in security and surveillance for military and commercial applications. Telephone jammers are their enemy.
"Human intervention is still very difficult in the United States, but the threat is growing," Stamatowski said. "If you look into the future, even five years from now, you'll see all kinds of robots. That's going to be key for us. In the infrastructure part, everyone's goods and services will depend on it. It is critical that we address the problem escalation method first, as this can be a real difficulty in any operation. We regularly attack offices in Israel - GPS is lost all over the country. This is a real test for our drones and shows that the industry has to be ready."
As the drone industry has grown, these tools have become more sophisticated, especially as people have begun to understand the value of the data collected by drones. It was with this in mind that Easy Aviation partnered with InfiniDome, which specializes in anti-jamming technology. They have jointly developed a small drone platform that integrates InfiniDome's GPSdome wifi blocker with Easy Aero's Intelligent Aerial Surveillance System (SAMS), the first of their kind.
Install jammers to reduce the risk of cheating
Mobile phone signal blockers are mainly used in various places where the use of mobile phones is prohibited, such as various examination rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals, government, finance, prisons, public places, etc. Security and military strength.
It is understood that the WiFi mobile phone signal blocker on the market can limit the mobile phone signal within 500 meters from the transmitting station and the radius is >20 meters. The shielding radius is adjustable, only shielding mobile phone signals, does not affect other electronic devices. Energy saving, power 20W-480W.
Cell phones operate within a certain frequency range. Mobile phones and base stations are connected by radio waves, and data and sound are transmitted through a certain baud rate and modulation. Taking into account this communication principle, the mobile phone signal jammer will sweep the frequency from the bottom of the front channel to the top at a certain speed during the operation. Mobile phone search network, no signal, no service system and other phenomena.
The Indian government has used telephone jammers in test centres.
Instead of giving the authorities a chance this time, the authorities arranged for the All India Pre-Medical Examination (AIPMT), which was overturned by the Supreme Court on Saturday at the Simrakandria Vidyalaya Supreme Court on the grounds of allegations of mass irregularities.
Metal detectors, network jammers and vulnerability detectors were installed for the first time at the test center, which will be conducted in 16 classrooms at Jaku School. The school requires at least 480 students to take the AIPMT retest. The school district has installed closed-circuit television cameras.
The school administration is responsible for the examination on behalf of 32 teachers. In addition to six supervisors, each class has two teachers. At least 15 police officers will secure the school.
On Thursday, a team from the Central Board of Secondary Education (CBSE) visited the centre to assess all arrangements.
Students must strictly adhere to the dress code set by the Board, or they will be allowed into the hall. - Light-colored half-sleeved shirt with no badges or fancy buttons, slippers (excluding shoes) and accessories.
Watches or other timekeeping gadgets are not allowed, it is not recommended to bring anything other than properly pasted photos and additional photos, and do not enter the examination room.
The AIPMT test was held earlier on May 3 and was taken by 630,000 students across 3,800 medical seats in 1,050 centres across India.
During the exam on May 3, the paper was leaked and answer sheets were distributed via electronic devices. The Supreme Court quashed its review in May.
Investigators said answers to 123 questions were sent via 75 mobile phones in Bihar, Jharkhand, Rajasthan, Haryana and several other states, so the test was cancelled.
This time, installing wifi jammers will greatly reduce the possibility of cheating.
