摘　　要：构建了一种实用的物理隔离网络双向数据传输模型,通过恶意软硬件植入、自主建立无线通道,为物理隔离网络数据窃取和双向传输创造了可能。围绕双向数据传输,研究了目标机控制、HID控制、无线AP控制、远程攻击机四个模块的功能和技术,实现了目标机和攻击机经由USB直连和无线网络转发的数据双向传输模式,支持目标机锁屏情况下的数据稳定传输。设计了集成度高、便携、可拓展的STM32Ducky便携设备。A practical two-way data transmission model of air-gapped network is constructed.Through malicious malware and hardware implantation and independent establishment of wireless channel,the possibility of leaking data and bidirectional transmission in air-gapped network is created.As for the bidirectional data transmission,the malware for target computer,hid control program,wireless AP control,and remote attack machine are explored,and the two-way data transmission mode of target machine and attack machine through USB direct connection and wireless network forwarding is realized,which supports the stable data transmission in the case of lock screen of target machine.The STM32Ducky portable device with high integration,portability and expandability is designed and developed.
