看到这个帖子https://www.52pojie.cn/thread-716901-1-1.html，想回复发现以前账号早就没了。这里写一下分析过程，能搞个账号最好，不能的话 @你有毒吧 童鞋来这里看分析吧。
首先下载vbs脚本 vscode打开，能看到的是一堆“乱码“，不过也有一定的规律。既然能正常执行，那么肯定至少格式是正确的，搜索冒号":"替换为换行"\n"，能让代码看起来稍微清爽一点
然后搜索"("，能找到几处函数和调用,贴一下关键地方

篇幅关系把nFattSGfzkORuQE 后面的一堆hex字符用xxxx代替了
看到有个Execute，说明至少解密了一层了，要继续解密得先用YPcXDTqcWJAjkyz函数解一层，直接把execute替换成写文件

打开output.vbs发现已经是解密完了，原始文件前前后后那么多的 随机字符串=随机字符串 只是掩护罢了，并没有实际作用的样子。
