安服崽日常做代码审计的时候，经常需要把已经发布的 java 项目反编译
之前一直都是把所有 jar 和 class 打进一个 zip 包，扔到 jd-gui，然后在 save all resource，这
种办法很蠢。
直到 bearcat 师傅发给我一个消息，我才发现，原来批量反编译 java 代码是这么简单的一件
事，只需要一个命令就可以了。
Idea 自带的反编译项目地址：https://github.com/fesh0r/fernflower
对我们安服崽来说还是不太方便，稍微做了一些改动，增加了筛选 class 的功能，黑白名单
方式让脚本只反编译我们需要的 class，仅仅只是 indexof 来做筛选

#proxyshell for workload
从发布上个文章后，好多从那个文章加微信的朋友都提到了负载问题，但是搬家没时

Wsman 发送请求时有顺序的序列，而遇到负载时这个特点会造成顺序发送请求时，

听说你在⽤SigFlip在PE签名⾥嵌⼊

真的隐蔽吗？真的不容易被查杀吗？

解析。例如，当你往HashSet 添加⼀个URL元素时，会触发URL 的hashCode() ⽅法⽐较
元素，然后发出⼀个DNS 请求。

越来越多的软件和网站都推出了夜间模式, 所以最近夜间冲浪的时候经常从黑色的IDE切换到白色的网页的时候,
总会瞎眼一波, 就从谷歌插件商店搜了几个能把网页转换成夜间模式的插件, 最终决定用Night Eye.
不同于一般的只会修改background-color: black的插件, 这款插件通过算法来进行各种颜色调整, 既可以让
网页变成夜间模式, 也不会导致黑色背景和黑色字体融为一体.

第⼀一步是⼀一个正则绕过：
