我从 Hotmail 发送的电子邮件中这些内容是什么？

我从我的 Hotmail 帐户向自己发送了一封电子邮件并查看了源代码。我从 www.Hotmail.com 执行此操作，仅发送了文本“测试”。

当我收到电子邮件时，我在 Outlook 中查看了源代码，看到的内容如下：

<html>
<head>
<style><!--
.hmmessage P
{
margin:0px;
padding:0px
}
body.hmmessage
{
font-size: 10pt;
font-family:Tahoma
}
--></style>
</head>
<body class='hmmessage'>
Test<script>try{if (typeof(lpcurruser) == 'undefined') lpcurruser = ''; if (document.getElementById('lpcurruserelt') && document.getElementById('lpcurruserelt').value != '') { lpcurruser = document.getElementById('lpcurruserelt').value; document.getElementById('lpcurruserelt').value = ''; } if (typeof(lpcurrpass) == 'undefined') lpcurrpass=''; if (document.getElementById('lpcurrpasselt') && document.getElementById('lpcurrpasselt').value != '') { lpcurrpass = document.getElementById('lpcurrpasselt').value; document.getElementById('lpcurrpasselt').value = ''; } var lploc=1;var lponlyfill=1;var link=document.getElementById("i1668"); if(link&&typeof(g_lpclicked)=="undefined"){if(document.createEventObject){var evt = document.createEventObject();link.fireEvent("onclick",evt);}else{var evt2 = document.createEvent("MouseEvents");evt2.initMouseEvent("click", true, true, document.defaultView, 1, 0, 0, 0, 0, false, false, false, false, 0, null);link.dispatchEvent(evt2);}g_lpclicked=1;}lpcurruser = ''; lpcurrpass = '';}catch(e){}</script><script>try{if (typeof(lpcurruser) == 'undefined') lpcurruser = ''; if (document.getElementById('lpcurruserelt') && document.getElementById('lpcurruserelt').value != '') { lpcurruser = document.getElementById('lpcurruserelt').value; document.getElementById('lpcurruserelt').value = ''; } if (typeof(lpcurrpass) == 'undefined') lpcurrpass=''; if (document.getElementById('lpcurrpasselt') && document.getElementById('lpcurrpasselt').value != '') { lpcurrpass = document.getElementById('lpcurrpasselt').value; document.getElementById('lpcurrpasselt').value = ''; } var lploc=2;var lponlyfill=1;var link=document.getElementById("i1668"); if(link&&typeof(g_lpclicked)=="undefined"){if(document.createEventObject){var evt = document.createEventObject();link.fireEvent("onclick",evt);}else{var evt2 = document.createEvent("MouseEvents");evt2.initMouseEvent("click", true, true, document.defaultView, 1, 0, 0, 0, 0, false, false, false, false, 0, null);link.dispatchEvent(evt2);}g_lpclicked=1;}lpcurruser = ''; lpcurrpass = '';}catch(e){}</script><script>try{if (typeof(lpcurruser) == 'undefined') lpcurruser = ''; if (document.getElementById('lpcurruserelt') && document.getElementById('lpcurruserelt').value != '') { lpcurruser = document.getElementById('lpcurruserelt').value; document.getElementById('lpcurruserelt').value = ''; } if (typeof(lpcurrpass) == 'undefined') lpcurrpass=''; if (document.getElementById('lpcurrpasselt') && document.getElementById('lpcurrpasselt').value != '') { lpcurrpass = document.getElementById('lpcurrpasselt').value; document.getElementById('lpcurrpasselt').value = ''; } var lploc=1;var lponlyfill=1;var link=document.getElementById("i1668"); if(link&&typeof(g_lpclicked)=="undefined"){if(document.createEventObject){var evt = document.createEventObject();link.fireEvent("onclick",evt);}else{var evt2 = document.createEvent("MouseEvents");evt2.initMouseEvent("click", true, true, document.defaultView, 1, 0, 0, 0, 0, false, false, false, false, 0, null);link.dispatchEvent(evt2);}g_lpclicked=1;}lpcurruser = ''; lpcurrpass = '';}catch(e){}</script><script>try{if (typeof(lpcurruser) == 'undefined') lpcurruser = ''; if (document.getElementById('lpcurruserelt') && document.getElementById('lpcurruserelt').value != '') { lpcurruser = document.getElementById('lpcurruserelt').value; document.getElementById('lpcurruserelt').value = ''; } if (typeof(lpcurrpass) == 'undefined') lpcurrpass=''; if (document.getElementById('lpcurrpasselt') && document.getElementById('lpcurrpasselt').value != '') { lpcurrpass = document.getElementById('lpcurrpasselt').value; document.getElementById('lpcurrpasselt').value = ''; } var lploc=2;var lponlyfill=1;var link=document.getElementById("i1668"); if(link&&typeof(g_lpclicked)=="undefined"){if(document.createEventObject){var evt = document.createEventObject();link.fireEvent("onclick",evt);}else{var evt2 = document.createEvent("MouseEvents");evt2.initMouseEvent("click", true, true, document.defaultView, 1, 0, 0, 0, 0, false, false, false, false, 0, null);link.dispatchEvent(evt2);}g_lpclicked=1;}lpcurruser = ''; lpcurrpass = '';}catch(e){}</script>                      </body>
</html>

那是什么？！？！

看起来至少有点可疑。有人知道 lpcurrpass 是什么吗？

编辑：对于超级用户来说，从 Hotmail 发送电子邮件是否不合适？有没有更合适的地方来问这样的问题？

答案1

谷歌搜索typeof(lpcurruser)显示它可能来自最后通行证，一个密码管理器。

一位用户发布了下一篇在他们的论坛上（注意：该链接来自 Google 缓存，您需要注册才能阅读它）：

如果我使用 Firefox 3.6.16 和最新的 LastPass 插件在 Facebook 上编辑文档，每次保存任何文档之前，都会将这个内容附加到文本字段中。我所说的文档是指在 Docs 部分中创建的文档。在其他字段或 Chrome 中不会发生这种情况。

现在这里的任何论坛都无法使用搜索功能，所以我不知道这是否是一个已知的错误。
