摘要:如今,上網(wǎng)瀏覽信息和收發(fā)電子郵件已經(jīng)是一件很普通的事情,但隨之而來卻是郵件病毒和網(wǎng)頁病毒的泛濫流行。2000年5月4日歐美爆發(fā)的“愛蟲”網(wǎng)絡(luò)蠕蟲病毒,由于是通過電子郵件系統(tǒng)傳播,因此在短短幾天內(nèi)狂襲了全球數(shù)百萬的電腦。微軟、Intel等在內(nèi)的眾多大型企業(yè)網(wǎng)絡(luò)系統(tǒng)癱瘓,全球經(jīng)濟損失達幾十億美元。而“新歡樂時光”病毒至今都讓廣大電腦用戶苦不堪言。
這些病毒最大的共同特點就是使用VB Script編寫。VB Script腳本語言功能非常強大,它們利用Windows系統(tǒng)的開放性特點,通過用一些現(xiàn)成的Windows對象、組件,可以直接對文件系統(tǒng)、注冊表等進行控制。原本是為了彌補HTML語言的缺陷,提供在網(wǎng)頁中與Web客戶交互的功能,但用心不良者卻利用他們來制造網(wǎng)頁病毒。
本文對網(wǎng)頁病毒這個“新概念”、網(wǎng)頁病毒形成原理和主要攻擊方式進行了闡述,通過長期對網(wǎng)頁病毒的制作方式、制作技術(shù)的觀察和分析,初步形成了以基本防御、一般手工清理、高級手工清理為四個層次的“四步驟”網(wǎng)頁病毒防御策略。

The computer web virus analysis and defense
Abstract:Today, Internet browsing and e-mail message is a very common thing, but it is followed by e-mail viruses and Web virus epidemics. May 4, 2000 in Europe and America broke out of the "Love Bug" network worm, because it is spread through e-mail system, so within a few days Kuang Xi millions of computers around the world. Microsoft, Intel, including many large-scale enterprise network system failures, global economic losses of several billion dollars. "New Happy Hour" virus majority of computer users today are so miserable.
Most common feature of these viruses is the use of VB Script writing. VB Script scripting language is very powerful, they use the open characteristics of the Windows system, by using some of the existing Windows objects, components, can be directly on the file system, registry and other control. Was originally designed to compensate for defects in the HTML language, provide customer interaction with the Web page functions, but those who have bad intentions to use them to create web viruses.
In this paper, Web virus this "new concept" virus formation and of the main page attack are described, through long-term virus production methods on the web, production techniques of observation and analysis, initially formed a basic defense, general manual cleanup, senior manual cleaning for the four levels of the "four steps" Web viral defense strategy.
