HackMyVm部分Windows系统的靶机，如DC02、DC03导入 VirtualBox时会报错，报错信息如下：
Failed to load the NVRAM store from the file (VERR_PATH_NOT_FOUND).
Can't attach Nvram Storage driver (VERR_PATH_NOT_FOUND).
返回 代码:
E_FAIL (0x80004005)

ConsoleWrap

解决方法：

这篇walkthrough是跟着靶机作者的wp写的，算是学习加记录，linux靶机玩多了换换win靶机，感觉挺有意思。

直接访问报错，需要在/etc/hosts里设置域名lookup.hmv，再次访问主页显示一个登录页面。
扫描目录没有发现什么敏感文件，也没有什么漏洞，sql注入也不行。只能尝试爆破，先尝试爆出用户名。这里要注意wfuzz的语法，特别是要用多个-H加入必要的头信息。

...HackmyVm的靶机Atom，下载地址是https://hackmyvm.eu/machines/machine.php?vm=Atom
正常nmap扫描，只能找到22端口，非常蹊跷。卡在第一步就非常郁闷了，cromiphi制作的靶机总是有点小坑的！
