In response to the issue of some companies using WiFi probes to collect personal information from CCTV 315 party, Huawei’s EMUI WeChat official account stated that Huawei mobile phones have enabled MAC address randomization by default, which can effectively prevent WiFi probes.
The gray and black industry exposed at the CCTV 315 evening party used the installation of WiFi probes to obtain the mobile phone WLAN MAC address, and then the mobile phone IMEI number, and then the user's mobile phone number, thus providing a source for harassing calls.
According to the official WeChat account of Huawei EMUI, the MAC address randomization function has been enabled by default in Huawei mobile phones EMUI 8.0 and above. MAC address randomization means that after the mobile WiFi is turned on, the MAC address carried in each scan of the surrounding WiFi hotspots is randomly generated Yes, even if it is acquired by the WiFi probe, it cannot do the correct big data matching.
In other words, the mobile phone MAC address obtained by the WiFi probe is not the real MAC address of your mobile phone, so the WiFi probe cannot collect the user's private information.
So how do some units go online when they bind mac to the Internet to confirm their accounts?
Each device in the network has a unique network identifier. This address is called the MAC address or the network card address, which is written in the hardware when the network device manufacturer produces it. As long as you do not change your MAC address, the MAC address is unique in the world. To put it vividly, the MAC address is just like the ID number on the ID card, which is unique.
If the user displays his real device MAC address every time he connects to the hotspot, then the user's MAC address may be collected and used. In response to this security risk, Huawei EMUI 10 randomly generates a MAC address by default when connecting to the hotspot; the connection is different In the hotspot, a random WLAN MAC address will be generated, so as to avoid the leakage of personal privacy due to the MAC address being collected.
After Huawei EMUI 10 is successfully connected to the WLAN, click on the connected hotspot to view the random MAC address used for this connection.
If you need to get the real MAC of the device, you can go to "Settings>System>About Phone>Status Message" to check the WLAN MAC address when the WIFI is turned on. The MAC address of the device is displayed here.
When connecting to a hotspot, a random MAC is used by default. If necessary (for example, the router has a whitelist, etc.), you can set whether to use a random MAC connection or a device MAC connection for each hotspot. The method of changing is also very simple. Click on the hotspot you want to connect to, in the password input interface, check "Show advanced options", click "Privacy", you can choose whether to use random MAC or device MAC for this connection.
For non-encrypted hotspots, you can slide to the bottom of the WLAN hotspot list interface and click the option "Add another network" to manually add the target hotspot, and choose whether to use random MAC or device MAC for this connection.
