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.

我将分享一个我创造的。种。

多年、多年、多年以前，我工作的公司需要在他们的ASP网站上建立索引。所以我去设置索引服务器，排除了一些管理目录，一切都很好。

然而，我不知道有人给了一个销售人员ftp访问网络服务器，这样他就可以在家工作，这是拨号的日子，这是他交换文件的最简单的方式....他开始上传东西，包括详细说明我们服务....标记的文档当人们搜索“成本”时，索引服务器就会索引并开始提供服务。

记住，孩子们，白名单不是黑名单。

我听说，当你以电子方式提交申报表时，Turbo Tax曾经以纯文本文件发送你的SSN。这似乎不是个好主意。

我还知道一家公司将信用卡信息存储在桌面上的纯文本CSV文件中。然后通过FTP发送到支付网关....

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。
