The infection of bitcoin and virus is mainly transmitted through network infection, which reflects the importance of network security, and the security of the network is related to network signals, including mobile phone signal, wifi signal and so on. For the current network security situation, in addition to improving its own network security awareness, the use of multi-functional cell phone signal jammer has become an important tool to protect the wifi network and mobile phone signal.For network security, the signal jammer has always been an important protection tool that intercepts signals and protects your network from attack.

In May 2017, an extortion virus called WannaCry swept the world, including more than 100 countries including China, the United States, Russia and Europe.

They used to be used for DDOS, but most of these chickens were used to dig mines this year.

As the digital currency prices, produce a kind of using the browser mining technology Coinhive, when a user to access the web page, dig program will work on Internet computer, take up a lot of system resources, cause the CPU utilization suddenly to ascend, as high as 100%.

At present, the network security environment increasingly complex, the network attack has diversified development, rising security experts warn broad user must improve the consciousness of network safety, recommended in daily use computer, open the system automatically update, patch in time, avoid the use of computer weak passwords, not an opportunity for criminals. When you find that your computer card is slow, you should check the CPU usage immediately. If any suspicious process is found, it can be shut down in time.

Internet security problems are frequent, and such news is often seen on the Internet. Xx's connection to public wifi leads to property theft, or the device connected to wifi becomes a bitcoin mining machine.Starbucks' wifi uses users' computers to dig? Hidden consumption trap in free network.
