基于Windows Script Host的简单RAT！想法来源于Koadic和JSRat-Py，并不是要做一款功能全面的强大的远控，最终目标是轻量、流量加密、免杀和CS加载器。

### Features

- 反弹上线/自动上线/无文件落地
- 流量加密(rc4)
- JScript代码混淆（XOR方式，下一步计划研究使用javascript-obfuscator）
- 命令执行
- 上传/下载
- shellcode注入(By DotNetToJS)

### Install

```
# git clone https://github.com/hanc00l/jscat
# cd jscat
# pip3 install -r requirements.txt
```

### Demo

```
➜  python3 jscat.py -h

usage: jscat.py [-h] --host HOST [-p PORT] [--new_key] [-s SLEEP_TIME]

optional arguments:
  -h, --help            show this help message and exit
  --host HOST           server foreign ip for host connect
  -p PORT, --port PORT  server listening port,default is 6600
  --new_key             generate new rc4 key to encrypt data
  -s SLEEP_TIME, --sleep_time SLEEP_TIME
                        set host sleep time in second,default is 5
