Unauthorized use of cell phone jammers is prohibited

In order to improve users’ perception and satisfaction, mobile companies have taken various measures for radio interference problems: First, establish a rapid praise channel and set up a special praise hotline to ensure that users report problems in a timely manner. user as soon as possible. The second is to increase publicity and education, create posters and single-page radio interference praise and relevant requirements for investigation and punishment, and post them in communities and group units, prompting users to set up mobile phone signal jammers and unauthorized speakers. This is a criminal act that can violate the criminal law. If the general public often encounters abnormal cell phone signals or WIFI signals, please report to the operator in time. The third is to coordinate with various parties to establish a clear coordination mechanism with the Radio Management Committee and the Public Security Bureau to ensure that operators, the Civil Affairs Commission, and the Public Security Bureau stop investigating and punishing behaviors that interfere with radio transmission. civic life. Normal life order, severe crackdown.

Start with the recently developed cell phone jammer devices. You can crack the password by cracking the encryption algorithm of the GSM alarm. Security experts calculated that the device would cost as little as $5,000 to manufacture. But now things are getting worse. I mentioned Don Bailey and Matthew Solnik before. I found a security hole in the GSM communication protocol. Even the latest GSM alerts with two-way communication and conversational codes are exposed to this vulnerability. A malicious person with technical knowledge can enter a vehicle with such an alert and even start the engine from a short distance.

All you need to do is send the alert a specific text audio with the desired action code. The opposite function works with various smartphone apps for car remote controls. Don Bailey and Matthew Solnic conducted many tests to find this flaw. “Just connect your laptop to a GSM network that supports M2M (Machine-to-Machine) technology. With this system, devices can exchange data over the GSM network. When you connect to the network, you are on the same GSM network. On. You will be able to connect. The automatic alarm will stop communicating. Now that you have found a way to send commands such as “shut down the alarm” or “start the engine”, you have full access to your vehicle.
