在文本框中输入1=1将列出系统中的所有用户。

事实上，只要使用文件/进程十六进制编辑器，就可以在大多数未加密的应用程序或文件上绕过安全性或预期功能。当然，在大多数游戏(在线或离线)中给自己无限的金币或上帝模式是很棒的，但它也很棒，只是抓取或编辑你想要的值，包括密码。事实上，有时候你只需要记事本。幸运的是，记事本不在DMCA联邦控制的计算机应用程序名单上…然而。

编辑:我指的是利用“皇帝的新衣”场景，用最简单的工具识别安全缺陷。这种场景在任何语言或平台的编程或消费者社区中都很常见，甚至可以成为通用标准。

信不信由你，我最近在一个网站上发现了这个:

eval($_GET['code']);

服务器甚至没有安全模式…

UNIX文本登录屏幕是如此容易复制…：）

I was going to earn my credit with the supervisor for my quite advanced graphics program at a SunOS / Solaris with instant messaging enabled where with zephyr.vars or whatever it was called you could make an image appear on your listed friend's screen like if you alowed me I could just send you an image that appeared on your display. While I was demoing the program I had written so that the supervisor could give me credit for it, one of my friends sitting close or in the next room made the photo big-mama.xxx appear on my screen. There was never any discussion or penalty because of the incident and I got credit for the project that for ½ second seemed like it was programmed to display big-mama.xxx instead of solving the problem. (Earlier) I updated perl scripts and waited for sysadmin to reflect the changes to ouside the FW. Then the database was gone and it was not a bug it was a feature since the data was stored with the source and therefore updating the source blanked the persistence.

物理访问或模拟登录提示或登录屏幕是另外两种困难的情况，不需要过多的算法技术，很容易理解物理访问提供了许多可能性，模拟登录提示是您可以在许多不同类型的计算机和环境上进行的事情。

我曾经有幸尝试保护一个网站(ASP Classic)，该网站“需要”密码才能访问管理界面。当然，如果你只是去其中一个管理页面的地址，你可以做任何你想做的，登录与否。

他们想知道自己是怎么被黑的。
