Sneaking in through the backdoor Spyware on the other hand secretly spies on PC and users and sneaks into the computer without the user’s knowledge. Forrester Research defines spyware as “any sort of code that records the behavior of the user without his or her explicit consent”. Spyware is not always aimed at targeting the user with advertising. What viruses and worms can do, spyware has been doing for a long time. As well as “remote control” of the PC by a third party, these spies also search for passwords or credir card details. In the worst cases, spyware records all the keystrokes and sends this log to a remote computer. While spyware is always an unwelcome guest on the PC, adware can be to the user’s benefit. Simply by surfing the Internet, a user can contaminate his or her PV with spyware. If the computer does not have the least patches, software can be installed secretly when opening a website. The big problem with detecting adware and spyware is that it is very hard to distinguish between good and bad by automatic means. Malicious spyware is in principle no different in terms of its structure to adware that the user wants to have on his computer or accepts as a way of financing a useful tool. The spread of spyware Adware and spyware are a phenomenon that has increased dramatically over the last few years. For example, a recent study by security company Blue Cost System found that 84 percent of 300 IT managers surveyed had witnessed an increase in or a consistently high level of spyware over the last three months. In a study conducted in spring 2004, web content filter provide Websense revealed that every third computer within a company is infected with spyware. An investigation by Equation Research commissioned by software manufacture Webroot found that over 80 percent of 275 IT managers surveyed had detected spyware on their systems. The figures seem to indicate a trend, with market researchers IDC reporting very sililat findings. According to an IDC study in December 2004, 67percent of all PCs have been attacked by spyware. The danger posed by this type of software in not to be underestimated. Meta Group classifies spyware as a “extended threats”. However, it is not just the criminal activities of malicious spyware that put companies under threat. Analysts believe the principle danger of adware and spyware lies in the fact that the software is often badly programmed and therefore undermines the stability of browsers and PCs. It occupies unnecessary bandwidths in the corporate network and keeps the user support busy with unstable clients, which results in additional costs. Forrester Research also warns about spies on the hard disk.” In additional to the impact on performance and bandwith, organizations have complained of information theft, in some cases, serious theft”, said a paper drafted in May 2004.

| Re. 发表于2005/4/26 10:43:00 从漏洞进入： 另一方面侦察软件可监测个人计算机和使用者，在使用者不知道的情况下偷偷的进入计算机。Forrester研究把侦察软件定义为“未经使用者明确同意而记录她或他行为的任何密码“侦察软件不总是通过广告来袭击使用者“。病毒和蠕虫所做的也是，侦察软件很长时间内一直所做的。个人计算机通过第三方的远程控制，这些侦察软件也可以搜索口令和信用卡详细资料。最坏的情况，侦察软件记录所有的按键，向远程计算机发送这个日志。当侦察软件一直是个人计算机不受欢迎的访客，对使用者有益。只通过网上冲浪，使用者就可用侦察软件使他或她的PV染毒。假如计算机没有补丁，打开一个网站的时候此软件就可能被秘密安装。 检测广告软件和侦察软件最大的困难就是很难自动区分软件的好坏。恶意的侦察软件原理上和广告软件的结构没有什么差异。而广告软件是使用者想要在他的计算机上使用的软件或者把它接受为作为一种支持有用工具的方式。
