Enter the “Victims Discovery”. Point the LAUNCH on your right, the system is scanning surrounding wireless networks.

After searching signal is completed, we will see some wireless networks, Select on and we can see this AP client, select one with many DATA, (We are based on an analysis of data packets to crack the password, so the more packets, crack faster).
