Summary of the method of mobile phone grasping package

1. Computer to do WiFi hotspot, mobile phone connected on the computer using Wireshark grab bag.

This method has no restrictions on the mobile phone, no root, jailbreak and so on, but also on the mobile phone system without any requirements, whether it is Android or iOS or other. When the phone is connected to a WiFi hotspot, the packet is bound to pass through the hotspot, then open the Wireshake, select the Wang Ke to do the hotspot, and click Start. This will capture the mobile phone and all network interaction packets.

Cons: Most systems are windows, unable to catch the lower 802.11 protocol package, but for the network layer and Transport layer, application layer packages such as tcp,udp,http and other protocols are still possible, so for most users have met the requirements.

2. Find a router, remove the password, then find an Apple computer, let the phone and the Apple computer are connected to the router, and then open the Wireshake on the evaluation computer, turn on the listening mode to grab the packet.

This method captures all packets on the router channel and now Home routers are mostly 2.4G bands, and most are the default settings, such as if the router channel is 6, then the Mac computer connected to the router after the channel is 6, at this time can catch 6 channels have been similar to the intersection of all the packets on the channel, including upstairs and downstairs neighbors and wireless mouse Bluetooth microwave oven, etc. also using 2.4G channels and and a package similar to the 6 channel. And because the MAC system network card driver design is better, so you can catch the lower 802.11 protocol package, as for the upper package that is even more.

Because the router does not have a password, so the packet caught does not need to decrypt, Wireshake identified is clear text data, can be directly analyzed.

Cons: You must have a Mac computer and a device that can do hot spots, and you will not be able to catch a cellular communication packet from 3G,4G. For example, GSM communication frequency is generally 900 to 1800MHz, and wireless network card is generally only support 2.4G or 5G, the frequency is much higher than GSM.
