Patent ID: 8464044

Claim:
A wireless network probe method, comprising: at a first station, broadcasting a probe request data packet across a network, to probe available wireless networks; receiving a beacon data packet regularly broadcasted by an access point (AP) that is connected to a wireless network, or receiving a probe response data packet sent by the AP as a reply of receiving the probe request data packet by the first station, wherein a service set identifier (SSID) is hidden in the beacon data packet or the probe response data packet, due to the wireless network closing the SSID; intercepting an encrypted data packet sent to the AP by a second station, which has established communication with the AP before the wireless network closes the SSID; amending data in the encrypted data packet to generate two attacked data packets; transmitting the two attacked data packets to the AP using a media control access address (MAC) of the second station, so that the two attacked data packets are regarded as being sent from the second station, to interrupt communication between the AP and the second station; intercepting a re-association request data packet sent to the AP from the second station and a re-association response data packet sent to the second station from the AP; and retrieving the SSID of the wireless network from the re-association request data packet or the re-association response data packet, and storing the SSID in the first station to connect to the wireless network.
