At present, criminals have implanted the chip into the roadside free mobile charging pile, if a mobile phone user uses the charging pile to charge, criminals can control the user's mobile phone through the chip. From the live experiment of CCTV March 15 Evening party, it can be seen that by casually using public charging piles, hackers can view photos in the charger's mobile phone, send text messages, steal the verification code of mobile phone users, and even consume.
is a chip, 315 is not said, now even charging will have hidden dangers in fact, I thinkThe best way is to install security software such as computer butler when using mobile phones or computers to enhance the most basic protection and avoid risks from the source.
The first is that the quality of these devices can not be guaranteed, and the charging speed is also very slow compared to the charger that comes with the mobile phone, which can not meet the needs of users. Secondly, after continuous development, the charging standards of each mobile phone brand are not the same, but these public devices are not adapted to mobile phones. The damage done to your phone's battery by using these devices is irreversible.
Yes. Certain common chargeElectrical appliances and data cables will induce the phone user to open USB debugging, in fact, this will give the phone's internal authority completely to the other party. Once it is clicked on, the computer, charging pile, etc. are connected to the mobile phone, and the mobile phone software can be secretly installed without the user's consent, or even malicious programs.
