DigitalWorld.Local:Bravery
有史以来在vulnhub下的最大的靶场了，害！
新建一个虚拟机，将iso和硬盘添加进去，但是会出奇奇怪怪的错误，尝试使用virtualbox进行打靶吧。（屈服.jpg）
扫描一下，看看对不对：
大概率没错了，可以开始攻击了。

使用enum4linux探测一下：

david
risk
anonymous
secured尝试连接一下，密码使用qwertyuioplkjhgfdsazxcvbnm看看有啥信息：
smbclient //10.160.86.46/anonymous提取不到信息，只能看到很多个文件夹。
smbclient //10.160.86.46/securedPassword for [WORKGROUP\root]:
tree connect failed: NT_STATUS_ACCESS_DENIED额，没有权限，嘶。如果密码没有问题的话，应该是用户名出错了，尝试使用david和risk进行登录：

I have concerns over how the developers are designing their webpage. The use of "developmentsecretpage" is too long and unwieldy. We should cut short the addresses in our local domain.
1. Reminder to tell Patrick to replace "developmentsecretpage" with "devops".
2. Request the intern to adjust her Favourites to http://<developmentIPandport>/devops/directortestpagev1.php.// genevieve.txt
Hi! This is Genevieve!
We are still trying to construct our department's IT infrastructure; it's been proving painful so far.
If you wouldn't mind, please do not subject my site (http://192.168.254.155/genevieve) to any load-test as of yet. We're trying to establish quite a few things:
a) File-share to our director.
b) Setting up our CMS.
c) Requesting for a HIDS solution to secure our host.// README.txt
README FOR THE USE OF THE BRAVERY MACHINE:
Your use of the BRAVERY machine is subject to the following conditions:
1. You are a permanent staff in Good Tech Inc.
2. Your rank is HEAD and above.
3. You have obtained your BRAVERY badges.

hack:$1$hack$xR6zsfvpez/t8teGRRSNr.:0:0:root:/bin/bash这是昨天刚搞的，可以使用openssl passwd -1 -salt hack hack生成的，本地创建一个passwd文件，然后传过去：
