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。

访问一个非常有名的在线商店的联系页面，向下滚动，搜索一个电话号码。相反，我发现了一个上传表单，它接受所有的文件类型，实际上把上传的文件放在网站的根文件夹中，这意味着如果一个人上传了一个名为test.php的文件，它将被url mydomain.com/test.php调用:)

由于他们使用osCommerce(开源)，因此编写一个脚本来获取所有数据库连接细节，然后下载他们完整的客户数据表，对于任何有足够智商的人来说，这将是不到五分钟的工作。

我联系了他们，最后得到了我下次购买的折扣券，他们在几分钟内删除了上传表单。

令人惊讶的是没有人提到社会工程，但我从这篇文章中得到了乐趣。

总结:恶意用户可以买几十个u盘，在里面装上自动运行的病毒或木马，然后在深夜把这些u盘撒在公司的停车场里。第二天，每个人都来上班，被闪闪发光的、糖果形状的、不可抗拒的硬件绊倒，并对自己说:“哦，哇，免费的闪存盘，我想知道里面有什么!”——20分钟后，整个公司的网络都被冲洗掉了。

我们有一个客户要求根据特定的HTTP引用器自动登录。所以你和我必须登录，但如果你点击了一个特定网站的链接，你就会自动以默认用户登录。

在一些Unix机器(当然是所有的SunOS)上，您可以将setuid shell脚本链接到一个名为“-i”的文件。 shell脚本将文件名解释为它的第一个参数，并运行"sh -i" =一个交互式shell，并获得setuid文件所有者的许可。

因为大多数setuid shell脚本都是以根用户身份运行的，以便允许您执行一些需要根用户权限的操作，比如弹出CD或加载磁带。这意味着在20世纪90年代，在大多数大学的Unix机器上获得管理是很简单的。

1-800 dominos will give unlisted address's related to any target phone number. When prompted if you are calling about the phone number you called from select no. The system will prompt you for a new phone number, the system will then read back to you the name and address that's associated to this phone number. Enter in your target's phone number and you now have their name and address. This is pretty common with automated ordering systems and if dominos has fixed this there are literally hundreds more.
