出于某种原因，你可能想在加载后不久按下停止按钮，否则它只是说由于某种原因连接重置…

去年，我发现我所在的公司用来处理支票/报表的网站充满了SQL注入漏洞。

不用说，他们很快就把洞补好了。

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。

不是最糟糕的，但很好笑的一个是Android操作系统重启的bug。当用户使用G1手机时，他们可以在手机的任何地方输入“重启”(比如:短信或电子邮件)，手机就会重新启动。

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.
