当关键IT员工离开公司时，不更改管理密码。

谁能忘记Windows 98的经典安全漏洞呢?

复制密码文本*********并将其粘贴到文字处理器中，就会显示几乎任何东西的密码。

IIS上的Web应用程序，没有文件上传过滤器。所以你可以上传exe，并做smf乐趣;)

最糟糕的安全漏洞是使用ie浏览器的选项来记住你的密码。人们没有意识到的是，像Nirsoft这样的工具可以泄露你所有的密码。

我们有一个旧的计算机集群，在我工作的一个实验室里没有运行。几个本科生认为，让它运行起来会很有趣，这样他们就可以学习一点并行计算了。他们让它运行起来，结果证明它非常有用。

One day I came in and was checking out the stats...It was running at 100%. Now this was a 24 node cluster and there were only 3 of us that ever used it so it was a little strange that it was running at this load. I started playing with it, trying to figure out what was loading it...turned out someone had gained access and was using it as their own little porn server and spammer. I asked the undergrads what kind of security they put on it, they looked at me and said "Security? We didn't think it would need any."

我给它加了个密码，就这样。把它用作色情服务器的人原来是一个本科生的朋友。

在PHP中，这是在第一个包含文件:

extract($_GET);
extract($_POST);

它允许覆盖未被_GET或_POST调用的变量。

我的一个朋友曾经知道一个站点将SQL查询作为GET参数传递。你知道有些人会拿这个开玩笑。
