这个v7的格式和常规的不一样,以前的混淆脚本第一行直接就定义了版本号变量,但是这个脚本将这个变量的定义放到了函数里,在函数内通过global 对象定义,并在脚本开头处调用:

_0x5e2b('0x0');
function _0x5e2b() {
    return global["_0xenty"] = Buffer["from"]('anNqaWFtaS5jb20udjc=', 'base64')["toString"]('utf-8')
}
function _0x5e2b() {
    global["_0xenty"] = Buffer["from"]('anNqaWFtaS5jb20udjc=', 'base64')["toString"]('utf-8')
}

由于global全局对象只存在于Node.js 环境中,在浏览器环境下会报错(这里的全局对象是window),所以之前的脚本没有出现这种形式。

我需要一点时间来添加对这种特征的支持,你如果着急的话,可以按下面的流程操作:

  1. 使用 de4js 解密
  2. 将第一行_0x5e2b('0x0');替换成var _0xenty="jsjiami.com.v7";
  3. 放到本插件解密
