By exploiting network vulnerabilities to turn your mobile phone into a distracting device and disrupt the small city network, you only need to make twelve calls. Researchers have found a way to make ordinary mobile phones. In some cases, jammers may interfere with other calls, such as BB in a movie theater, classroom or meeting room. Phone calls are prohibited in some places. The prison will install cell phone jammer to prevent prisoners from claiming to be a prison. This “trouble” is not suitable for personal use, expensive and low energy consumption. Because they prevent emergency calls, they also pose security risks. Now, computer scientists have shown that even business phones can be changed due to software changes. The team led by the Institute of Software Technology and Theoretical Computer Science exchanged software on mobile phones and took advantage of their weaknesses in the GSM radio standard. Computer scientists presented their research results at a security seminar and will develop an electronic device that can suppress cell phone signals.
The Russian Ministry of Defense announced on November 6 that the country has increased the range of the jammer carried by its drones to 100 kilometers, or more than 60 miles. UAVs are platforms for electronic warfare, not just targets. This means that the sight of robots flying in the air can signal an impending strike and a sudden inability to seek help. Samuel Bendit, a research analyst at the Naval Analysis Center, said: “Russia has been using mobile phone jammers installed on drones for many years.” The drones work in a pod, and there are two to three in the pod. A vehicle and a ground station, they are combined into the “empty 3” system. Bendit said: “When these drones fly in groups, one acts as a signal and communication relay, and the other acts as a jammer.” “Currently, these Leer-3 systems have existed for about two years.”
What has changed is the range of the jammer. The Orlan-10 drone has a range of 75 miles, which means that in the latest jammer update, the drone pod can interfere with signals up to 135 miles from the launch site of the drone. TASS reports that the 60-mile range is 3.5 times greater than the original range. In addition, Bendit said that this capability or its earlier versions may have conflicts.
