这次得到第1个flag,从FTP上下载到Kali Linux指的分析一下。
接下来用john the Ripper工具破解一下加密的zip文档，先用之前得到的dict.txt作为字典试一下：

看来这次需要用rockyou.txt作为密码字典进行破解，成功得到密码，将zip文档解密。
解密后得到一个WAV文件以及txt文档，txt文档好像没啥用，WAV会不会用到最开始尝试的工具Soundstegno工具进行分析。

加密算法是这里支持移动3位，这应该指的是凯撒加密，用在线网站

解密得到：

这里得到的用户名和密码应该是/cms/admin的登录信息，手动验证属实。
此时就可以前面查询得到的漏洞利用脚本进行漏洞利用。
