我之前至少有一个同事可能符合这个条件。

整个经典ASP购物车“Comersus”。整个事情是意大利面条代码的混乱，所有的SQL语句都是成熟的SQL注入，因为没有做任何过滤。可悲的是，我不幸地处理了近两年的“申请”，这绝对是一场噩梦!

我曾经听说过一个在银行工作的程序员，他们以小数点后16位的精度计算他们的内部数据(包括账户余额)。

所以这个家伙改变了银行转账程序，每笔交易将0.00001美元转到他自己的账户，剩下的转到原来的目的地。我认为他们很快就抓住了他，但我不得不承认，当我第一次听说他的想法时，我觉得它很好。

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.

几年前我移植的一款遗留应用使用了第三方回调系统来处理支付。问题是，回调脚本没有检查支付的金额是否等于订单的价格，因此可以使用Firebug编辑支付页面上“金额”字段的内容，以0.01英镑的价格购买网站上的任何产品。
