| Summary: | For traditional physical attacks such as side channel attacks and HID attacks in real networks,physical isolation is considered to be a relatively complete security protection against network attacks.In 2018,a Wi-Fi hidden channel method in the physical isolation environment——Ghost Tunnel was firstly proposed,that is,in the state that Wi-Fi didn’t connected,the wireless AP could successfully transmit data to the computer that initiates the connection request.An attack framework based on the Ghost Tunnel method——GreyFan was proposed.This attack framework enabled attackers to implement non-aware attacks on users who didn’t connected to Wi-Fi,such as file concealed transmission and arbitrary code execution,etc.The corresponding defense technology was also analyzed. |
