In the field of Computing , the term spyware refers to a broad category of Malicious Software designed to intercept or take partial control of a Computer 's operation without the Informed Consent of that machine's owner or legitimate user. While the term taken literally suggests software that surreptitiously monitors the user, it has come to refer more broadly to software that subverts the computer's operation for the benefit of a third party. Spyware differs from Viruses and Worms in that it does not usually self-replicate. Like Many Recent Viruses , however, spyware – by design – exploits infected computers for commercial gain. Typical tactics furthering this goal include delivery of unsolicited Pop-up Advertisement s; theft of personal information (including financial information such as Credit Card Number s); monitoring of Web-browsing activity for Marketing purposes; or routing of HTTP requests to advertising sites. As Of 2005 , spyware has become one of the pre-eminent security threats to computer-systems running Microsoft Windows Operating-system s (and especially to users of Internet Explorer because of that browser's collaboration with the Windows operating system). Some malware on the Linux and Mac OS X platforms has behavior similar to Windows spyware, but to date has not become anywhere near as widespread. HISTORY AND DEVELOPMENT The first recorded use of the term ''spyware'' occurred on . Wienbar, Sharon. " The Spyware Inferno ". ''News.com''. August 13, 2004. Since then, computer-users have used the term in its current sense. In early 2000, Steve Gibson of Gibson Research realized that advertising software had been installed on his system, and he suspected that the software was stealing his personal information. After analyzing the software he determined that they were adware components from the companies Aureate (later Radiate) and Conducent. He eventually rescinded his claim that the ad software collected information without the user's knowledge, but still chastised the ad companies for covertly installing the spyware and making it difficult to remove. As a result of his analysis in 2000, Gibson released the first anti-spyware program, OptOut, and many more software-based antidotes have appeared since then. International Charter now offers software developers a Spyware-Free Certification program. " Spyware Certification ". ''International Charter''. Retrieved July 10, 2005. According to a November 2004 study by AOL and the National Cyber-Security Alliance , 80% of surveyed users' computers had some form of spyware, with an average of 93 spyware components per computer. 89% of surveyed users with spyware reported that they did not know of its presence, and 95% reported that they had not given permission for the installation of the spyware. " AOL/NCSA Online Safety Study ". ''America Online'' & ''The National Cyber Security Alliance''. October 2004. SPYWARE, "ADWARE", AND TRACKING The term '' Adware '' frequently refers to any software which displays advertisements, whether or not it does so with the user's consent. Programs such as the Eudora mail client display advertisements as an alternative to Shareware registration fees. These classify as "adware" in the sense of advertising-supported software, but not as spyware. They do not operate surreptitiously or mislead the user. Many of the programs frequently classified as spyware function as ''adware'' in a different sense: their chief observed behavior consists of displaying advertising. s. Other spyware behaviors, such as reporting on websites the user visits, frequently accompany the displaying of advertisements. Monitoring web activity aims at building up a marketing profile on users in order to sell "targeted" advertisement impressions. The prevalence of spyware has cast suspicion upon other programs that track Web browsing, even for statistical or research purposes. Some observers describe the Alexa Toolbar , an Internet Explorer plug-in published by Amazon.com , as spyware (and some anti-spyware programs report it as such) although many users choose to install it. ROUTES OF INFECTION Spyware does not directly spread in the manner of a computer virus or worm: generally, an infected system does not attempt to transmit the infection to other computers. Instead, spyware gets on a system through deception of the user or through exploitation of software vulnerabilities. The most direct route by which spyware can infect a computer involves the user installing it. However, users tend not to install software if they know that it will disrupt their working environment and compromise their privacy. So many spyware programs deceive the users, either by Piggybacking on a piece of desirable software, or by tricking the users to do something that installs the software without them realizing. Recently, spyware has come to include "rogue anti-spyware" programs, which masquerade as security software while actually doing damage. Classically, a Trojan Horse , by definition, smuggles in something dangerous in the guise of something desirable. Some spyware programs get spread in just this manner. The distributor of spyware presents the program as a useful utility — for instance as a "Web accelerator" or as a helpful Software Agent . Users download and install the software without immediately suspecting that it could cause harm. For example, Bonzi Buddy , a spyware program targeted at children, claims that: He will explore the Internet with you as your very own friend and sidekick! He can talk, walk, joke, browse, search, e-mail, and download like no other friend you've ever had! He even has the ability to compare prices on the products you love and help you save money! Best of all, he's FREE! | ||
