一个让我害怕的安全漏洞是在我曾经维护的一个遗留应用程序中，其中有一个settings.ini文件，其中的数据库凭据是纯文本的，所有用户密码都以纯文本的形式存储在数据库中。

我见过的大多数安全漏洞都发生在我的高中和大学。

首先，我发现我可以通过(非常简单的)ping flood攻击来关闭学校的互联网。不仅仅是我高中的互联网，整个学校系统，包括大学的一部分。绝对没有速率限制。在我演示之后，他们最终把它修好了。(顺便说一句，我的第一份编程工作就是靠这种“宣传”获得的)

第二点，也是可能性更大的一点是:

Ok, so every computer in the school was connected to a domain and such. So, when you logged onto a computer, it would copy down a generic user directory(including application data, etc folders) and then proceed with the login. Some people had their own logins other than the generic "student" account for one reason or another. Well, while I was browsing the public server where everything was shared on, I found a /users directory. Upon looking at it I discovered froma generic student account I had read-write to every users directory, including teachers, administrator, and the generic student account.

为了愚人节，我计划写一个简单的批处理文件或小程序，弹出一些类似Class of 09 rocks的东西!登陆每个人只是为了演示它，但我退缩了。我也从来没有告诉过管理员，所以这个安全漏洞可能仍然存在。

Windows 95和98有史上最严重的漏洞。如果你只是按下取消，你将以管理员权限登录:)在我爸爸的工作中度过了美好的时光:D

新闻标题是在这条线索的精神…在今天的头版/。 ISP将客户数据库电子邮件发送给数千人

我最后工作的公司的FTP用户名和密码与他们的域名相同。他们不太在意反复警告。

不用说，网站没过多久就倒闭了。没有在线备份，所以他们不得不重建整个系统。但这并没有结束。这次事件后的新安全密码是一样的…加上123。

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。

In the 1970's Stanford had IBM 2741 hardcopy terminals spread around campus networked to an IBM 360/67. Account passwords were three characters. During logon, the password prompt would overprint a three-position blob of about nine random uppercase characters, so the subsequently-typed password would supposedly be masked by the blob. However, everyone typed their passwords in lowercase, which were trivial to discern against the uppercase background blob. That meant you could usually walk up to any terminal, peruse the hardcopy typically left behind by the previous user, and easily logon with their account and password.
