New Threats to Vehicle Hijacking in South Africa: The Rise of Signal Jamming

　　South Africa has been a global hotspot for car hijacking and theft, with criminals using a variety of means to threaten car owners and drivers. https://www.silencejammer.com/ In recent years, a new criminal method has been spreading rapidly, which is the use of signal jamming technology to prevent car owners from locking their vehicles normally, resulting in the theft of vehicles and valuables. https://www.silencejammer.com/mobile-jammer-cell-phone-blocker Charnel Hattingh of Fidelity Services Group said that people who have experienced remote jamming will feel helpless and frustrated, and this new criminal method has made the security situation in South Africa worse. https://www.silencejammer.com/gps-jammer-blocker-car-signal

　　What is signal jamming?

　　A signal jammer is a device that can emit interference signals to disrupt the transmission of radio waves or other electronic signals. It can prevent specific devices, such as remote control locks, GPS trackers and smartphones, from receiving or sending signals. This means that criminals only need to use signal jammers to block the vehicle's locking signal when you lock your car, so as to easily open the car door and steal valuables in the car. https://www.silencejammer.com/wifi-jammer-bluetooth-blocker-device

　　Ryno Schutte of Pro-Active noted that the use of signal jammers is increasing rapidly in South Africa, especially in the transport sector, where criminals are hijacking goods and vehicles by jamming GPS and GSM signals. The devices are small and portable, and very simple to use, so they are widely used in various crimes, especially for vehicle theft and hijacking.

　　How signal jammers work

　　The core principle of signal jammers is to interfere with the communication between the vehicle and the key by emitting radio waves at the same frequency as the vehicle's remote lock signal. When the owner presses the remote lock button, the key will emit a lock signal, and the signal jammer prevents this signal from reaching the vehicle by emitting a strong jamming wave, making the owner mistakenly believe that the vehicle is locked, but in fact the door is still unlocked. Criminals can easily open the door and steal the contents of the car after the owner leaves.

　　This method of crime has spread rapidly, especially in cities such as Johannesburg, and has become a new means of stealing vehicles and their contents. Criminals use portable signal jammers to easily commit crimes in busy shopping malls, parking lots and other places, and car owners often do not find out that the items in the car have been looted until they return to their cars.

　　The impact of signal jamming on South African society

　　In recent years, signal jamming crimes in South Africa have shown an upward trend year by year, especially in the transportation industry and personal vehicles. Schutte pointed out that criminals can easily prevent vehicles from being tracked and locked by illegally purchasing GSM and GPS jammers, and can even operate vehicles at will after the vehicle's GPS tracker is disabled. The abuse of this technology has had a serious impact on South Africa's security and economy.

　　Increase in theft cases

　　The number of thefts using signal jammers is increasing, especially in busy parking lots in large cities. Criminals target car owners who rely on remote control to lock their cars and steal by jamming their locking signals. According to statistics, in Johannesburg alone, the number of vehicle thefts related to signal jamming increases by more than 15% each year.

Introduction

The presence of illegal mobile phones in prisons enables prisoners to continue their criminal activities, posing a serious threat to prisons and social security. signal jammer This article explores the sources, uses, and existing and potential technical solutions for mobile phones in prisons.

　　Use of mobile phones in prisons

　　NOMS reports that prisoners use these phones to carry out a range of criminal activities, including commissioning murders, planning prison breaks, importing automatic firearms, and arranging drug smuggling. Wifi jammer Several cases show that prisoners organize criminal activities in prisons, posing a serious threat to social security. 

　　How mobile phones enter prisons

　　The mother of a prisoner in Northumberland County Prison claimed that "this place is full of mobile phones." Mobile phones enter prisons in a variety of ways, such as being thrown over the fence or delivered by prisoners using drones. Glyn Travis of the Prison Officers Association (POA) pointed out that drugs and mobile phones are thrown into prisons at will, and drone delivery completely undermines external security.

　　Technical solutions and costs

　　The technical solutions proposed by the Prison Service include jamming, grabbing, operator disconnection and intercept and search:

　　Jamming/jamming: Sending a signal to block mobile phones from receiving base station signals, all mobile phones and SIM cards within the jammer's range will be blocked. This method is cheap and very effective, but may cause interference outside the prison, increasing costs.

　　Grabbing: Mobile phones are attracted to a fake network, which is selective and can whitelist unaffected phones. Success can be quantified and illegal phones can be monitored, but the cost is high.

　　Operator disconnection: The Serious Crime Act 2015 introduced the power to force mobile phone operators to disconnect the network, but the relevant regulations have not yet been promulgated. Operators may be reluctant to cooperate, and disconnected phones and SIM cards can be easily replaced.

　　Intercept and search: Searching visitors and staff, searching cells and prisoners, and training sniffer dogs to find mobile phones, but these measures also have their limitations.

　　Although these technical solutions seem effective, NOMS said the cost is "disproportionate". For example, the cost of installing and maintaining jammers is hundreds of millions of pounds.

　　Laws and punishments

　　The Crime and Security Act 2010 makes possession of a mobile phone in prison punishable by up to two years in prison and/or an unlimited fine. However, Mr Travis of the POA said that prisoners do not worry about being punished for committing crimes in prison. Many prisoners are not severely punished for this, which makes the problem of mobile phones in prison even worse.

　　Future efforts and reforms

　　The Prison Service admitted that prisons "need urgent reform" and must "find new ways to find and block mobile phones and equip prison officers with the right tools to deal with these problems." Although the 2012 law allows the use of "signal denial" technology, its actual application remains limited. The POA has been lobbying for signal blockers for many years, but each attempt has failed due to various problems.

　　Mr Rogers pointed out that the use of technology can see how many mobile phones are disabled and who they belong to, while blocking technology sometimes leaves small spots where the signal breaks through, making the impact difficult to quantify. A spokesman for the Prison Service also said that relevant regulations will be "introduced in due course."

　　Background and current situation

　　In recent years, experts have become increasingly concerned about Russia's GPS interference on European aviation flights. Interference incidents have occurred frequently, affecting civilian flights in the Baltic Sea, the Black Sea and the eastern Mediterranean. signal jammer The Baltic States are particularly affected, which is one of the areas where Russian military activities are most frequent. On May 2, 2024, BBC Monitoring Russia Editor Vitaly Shevchenko reported on the situation, citing relevant data and views from Finnair and the European Aviation Safety Agency (EASA).cell phone jammer

　　Finnair reported that its flights to Tartu, Estonia were severely affected due to GPS signal interference.Wifi jammer In March this year, the Royal Air Force aircraft carrying British Defense Secretary Grant Shapps also encountered GPS signal interference when approaching Russian territory. GPS jammer Because Tartu Airport relies on GPS signals, Finnair had to suspend this route for a month. Juho Sinkkonen, vice president of flight operations at Finnair, said that although these interferences are mainly nuisance in nature, they still pose a potential threat to aviation operations.

　　Impact and response of GPS interference

　　Despite the frequent interference incidents, airlines and safety experts believe that GPS interference poses a limited direct threat to flight safety. This is because modern aircraft are able to use other navigation systems during flight to ensure safety during approach and landing. However, interference still leads to reduced operational efficiency and increased pilot workload.

　　Cyrille Rosay, a senior cybersecurity expert at the European Aviation Safety Agency, pointed out that although the interference problem existed before Russia invaded Ukraine in February 2022, it has worsened in recent years. Rosay said that EASA records thousands of interference incidents every year, showing the severity of the problem. The British Ministry of Defense also confirmed that the GPS signal of the plane that Shapps was on was interrupted on its way back to Poland.

　　Introduction

　　The Los Angeles Police Department (LAPD) recently warned residents of a surge in home burglaries, with criminals using Wi-Fi jammers to disrupt security cameras and smart doorbells to gain access to homes. This trend is particularly prominent in the Wilshire area, and police are reminding residents to take extra security measures to protect their homes. signal jammerThis article will take a closer look at how this criminal tactic works, how the police respond, and what residents can do to prevent it.

　　How Wi-Fi Jammers Work

　　A Wi-Fi jammer is a device that emits a powerful signal to interfere with wireless network devices. cell phone jammer Criminals use these jammers to interrupt communications in home security systems, making security cameras and smart doorbells unable to work properly, thereby achieving silent intrusions. Although these jammers are easy to buy online and inexpensive, it is illegal to use such devices in the United States. Wifi jammer

　　Specific Case Analysis

　　According to the LAPD, in burglaries in the Wilshire area, multiple suspects used Wi-Fi jammers to successfully break into victims' homes and take away a large number of valuables. These cases usually involve 3-4 criminals who first use jammers to disable security devices and then enter the house through the second-floor balcony to look for high-end jewelry, cash and other valuables. In addition, the criminal gangs usually arrange a driver to keep watch outside to ensure that they can quickly escape the scene.

　　Police response measures

　　The Los Angeles Police Department has taken active measures to deal with this new criminal method, including issuing warnings and safety tips on social media. They also provide a detailed safety checklist and recommend residents to strengthen physical security measures, such as protecting circuit boxes, installing hard-wired anti-theft alarm systems, upgrading lighting equipment, and trimming shrubs and trees.

　　Residents' precautions

　　To deal with the threat posed by Wi-Fi jammers, residents need to take multiple measures to improve home security. First, consider installing hard wiring for security systems to avoid relying entirely on wireless networks. Second, use complementary technologies such as Apple AirTags and Ring Doorbell to increase security coverage. In addition, residents should avoid revealing too much personal information on social media, especially plans to go out on vacation.
