摘  要
随着互联网技术的迅猛发展，网络给人们带来了很多便利，日益发达的网络产品越来越多。伴随这样的发展，随之而来的是越来越多的帐号与密码，而这些帐号与密码背后伴随的是很多的经济价值。在这种状况下，很多人想尽一切办法的去找取配套的密码与帐号,所以为了使帐号与密码更加安全，有必要去研究盗号木马的工作原理。
文章从木马的发展历史出发，介绍了木马的特点和工作原理，详细分析并设计实现了一个基于windows操作系统的盗号木马软件。在具体设计实现中，首先对本软件具有的功能和特点进行了分析，将系统划分为自动隐藏、自动运行、记录键盘三大主要模块，并选择了合适的开发环境；其次根据软件工程的要求做了逻辑设计；最后是编码实现和测试，并且对测试结果进行了分析。

关键词：自动隐藏；自动运行；记录键盘

The Design of Trojan Program for Account Number Purloining in the Windows OS
Abstract
With the development of the Internet, much facility has been brought to us by more and more network products. More and more account numbers and passwords have been appearing with the development. They could bring a great number of economic values. In this case, many people begin to try their best to find the suited account numbers and password. So in order to make them safe, it’s necessary to learn the theory of them.
This thesis starts with the Trojan development history, introducing its features and working principle, giving a detailed analysis and designing of stealing software based on windows operation. During the design, it first analyzes the software's functions and features, dividing the system into three modules: automatic concealment, automatic running and record the keyboard. It chooses the proper development environment, and makes a logic design based on the requirements of the software project; finally it conducts the coding and tests and then analyzes the result of test.

Key words：automatic concealment；automatic running；keyboard recording
