Recently, we found that the system has a wireless NIC driver. You can use a simple command to create a wireless network access point. With this free virtual wireless route, we can control the Wi-Fi data of our mobile phone! Packet capture, sniffing, protocol analysis, traffic hijacking, and code injection... Let's take full advantage of what you want to do ~
First, sniff mobile phone data packets.
It is very easy to create a virtual access point in win7. You only need two lines of command:
