这个样本有obfuscator的影子,但是从各方面看都不像是obfuscator某个版本分支的修改:

  • 在复杂度上,obfuscator引入了针对局部作用域的嵌套形stringArrayScopeCallsWrapper,但该样本只存在全局的StringArrayCall
  • 在细节上,对于StringArrayRotateFunction,obfuscator在第一个提交就是用的WhileStatement(UnicodeArrayRotateFunctionTemplate),但样本中用的ForStatement

在已有的obfuscator插件中适配这个样本不太现实。

这个和第一个有点类似,在结构上稍微有点区别,倒是和 #98 的差不多(主要的混淆逻辑基本一致)

这几个issue中的代码大部分是同一个作者,应该是他自用的混淆工具

增加索引

Env("酷我音乐");
NAME = "中国联通";
VALY = ["zgltck"];
VER = "1.1.6";
CK = "";
LOGS = 0;
usid = 0;
Notify = 1;
let helloword_0x5c6195 = require("fs");
let helloword_0x1a9fab = require("uuid").v4;
DCFHOST = process.env.DCFHOST;
dcfkey = encodeURIComponent(process.env.dcfkey);
IP = "";
IPCITY = "";

因为没有适配呢,这种私有混淆工具,你跟不上他的更新速度
