在这里根据记忆来解释，但它很接近……

我认识的一个家伙用这个来保护他网站的“私人区域”。起初，他不愿意相信我，甚至他的浏览器都有这个不可靠的“查看源代码”功能。

在没有加密的数据库中存储信用卡信息(整个信息:号码+有效期+密码)。此外，该数据库被用作一种CRM，因此许多销售人员可以使用不安全的密码访问它。(自从我3年前离开公司后，他们就没换过名字。)

About 3 years ago I built a site for a somewhat large non-profit organization in our state. When it came time to deploy the application to their web host server, I noticed an odd file named "cc.txt" or something obvious like that in their public site. It was under their web root, was getting served, and was a csv file of all their donor's names, addresses, credit card numbers, expiration dates, and CVV/CVC codes. I cannot count the number of times I brought the issue up - first to my boss, then our company accountant, the client's IT director, finally the client's President. That was 3 years ago. The file is still being served, it can even be googled. And it's been updated. I tend not to respond to their donation solicitations when I get them.
