I was going to earn my credit with the supervisor for my quite advanced graphics program at a SunOS / Solaris with instant messaging enabled where with zephyr.vars or whatever it was called you could make an image appear on your listed friend's screen like if you alowed me I could just send you an image that appeared on your display. While I was demoing the program I had written so that the supervisor could give me credit for it, one of my friends sitting close or in the next room made the photo big-mama.xxx appear on my screen. There was never any discussion or penalty because of the incident and I got credit for the project that for ½ second seemed like it was programmed to display big-mama.xxx instead of solving the problem. (Earlier) I updated perl scripts and waited for sysadmin to reflect the changes to ouside the FW. Then the database was gone and it was not a bug it was a feature since the data was stored with the source and therefore updating the source blanked the persistence.

物理访问或模拟登录提示或登录屏幕是另外两种困难的情况，不需要过多的算法技术，很容易理解物理访问提供了许多可能性，模拟登录提示是您可以在许多不同类型的计算机和环境上进行的事情。

最不可原谅的安全漏洞，不幸的是，一个非常常见和容易找到的漏洞，是谷歌黑客。举个例子:

http://www.google.com/search?q=inurl%3Aselect+inurl%3A%2520+inurl%3Afrom+inurl%3Awhere

令人惊讶的是，互联网上有多少页面，特别是政府网站，通过查询字符串传递SQL查询。这是最糟糕的SQL注入形式，查找易受攻击的站点毫不费力。

经过一些小的调整，我已经能够找到未受保护的phpMyAdmin安装，未受保护的MySQL安装，查询包含用户名和密码的字符串，等等。

对我来说，情况并没有那么糟糕，因为数据并不是那么敏感:

我得到了一个Excel文件，里面满是要更新的宏，每个表都是锁定的，宏部分有密码保护。我拿到了密码，但我想我还是试着破解一下吧。

我找到了一个程序，可以在大约十分钟内完成，其中大部分时间可能只是下载时间。这个神奇的产品是什么，能如此快速和轻松地突破Excel安全?OpenOffice.Org。

我不确定Office 2007是否在这一点上有所改进，但让我感到害怕的是，许多非技术人员可能正在使用Excel来操作敏感信息，并认为它是安全的。然而，这些类型的人可能甚至不知道它提供的“安全”功能。

我希望你能发现这里的问题。(事实上，大错特错):

String emailBody = "";

for (int i = 0; i < subscribers.Count; i++)
{
    emailBody += "Hello " + subscribers[i].FirstName + ",";
    emailBody += "this is a reminder with your account information: \n\n:";
    emailBody += "Your username: " + subscribers[i].Username + "\n";
    emailBody += "Your password: " + subscribers[i].Password + "\n";
    emailBody += "Have a great day!";

    emailDispatcher.Send(subscribers[i].EmailAddress, emailBody);
}

最后一个接受者是最幸福的;)

我们有一个客户要求根据特定的HTTP引用器自动登录。所以你和我必须登录，但如果你点击了一个特定网站的链接，你就会自动以默认用户登录。

我曾经有幸尝试保护一个网站(ASP Classic)，该网站“需要”密码才能访问管理界面。当然，如果你只是去其中一个管理页面的地址，你可以做任何你想做的，登录与否。

他们想知道自己是怎么被黑的。
