Right at the start of the .com era, I was working for a large retailer overseas. We watched with great interest as our competitors launched an online store months before us. Of course, we went to try it out... and quickly realized that our shopping carts were getting mixed up. After playing with the query string a bit, we realized we could hijack each other's sessions. With good timing, you could change the delivery address but leave the payment method alone... all that after having filled the cart with your favorite items.

"select * from LoginMaster where UserId='" + txtUserId.Text + "' 

                           and Password='" + txtPassword.Text + "';"

我曾在一个经营直销业务的生产网站上看到过这种情况。上面的Sql语句非常非常容易受到Sql注入的攻击。

我还将在这里列出HACME银行。根据网站Hacme银行是:

Hacme Bank™ is designed to teach application developers, programmers, architects and security professionals how to create secure software. Hacme Bank simulates a "real-world" web services-enabled online banking application, which was built with a number of known and common vulnerabilities. This allows users to attempt real exploits against a web application and thus learn the specifics of the issue and how best to fix it. The web services exposed by Hacme Bank are used by our other testing applications including Hacme Books and Hacme Travel.

在我尝试的一个免费网络主机上，用“忘记密码”的方法将密码发送给你时出现了一个逻辑错误——如果你没有输入电子邮件地址(辅助电子邮件是可选的)，它会将主地址的密码通过电子邮件发送给每个没有提供辅助电子邮件的用户。

一天，我和其他数百人收到一封电子邮件，里面有数百个用户名和密码，密码都是明文。

login.jsp?type=user&redirct=/home.jsp&userid=12345&username=username&password=mypassword

这发生在一个非常大的网站上。当我看到这个的时候，我惊呆了。

一家销售电脑的公司用FrontPage建立了一个网站，每个人都可以完全访问。

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。
