How does a wifi router read short messages in the background?

The user's mobile phone login information or mobile phone communication transmission information can be obtained by logging in the router linked to the network for packet capture analysis. To achieve this goal, it is not necessary to implant and install plug-ins logged into the mobile phone in the user's mobile phone.

Through USB***, just share the WIFI of the mobile phone with the computer. Ordinary mobile phones have this function.

The mobile phone can log in to the router background to query. Generally, routers can record the information of successfully linked mobile phones, including mobile phone model, mobile phone MAC and other information. This is mainly a question of identification and authentication. The MAC of a mobile phone is the only identification information of the mobile phone. If you want to link, you must upload information.
