复制代码通过以上几个蠕虫,我们可以总结蠕虫的工作原理为: e. x/ V$ m' w
1:首先写入调用蠕虫代码到一个存在XSS漏洞的位置(在非长久性XSS漏洞里,我们也可以通过把短暂性的XSS连接通过各种传播方式,发送给其他用户,当某个用户中了XSS后,再通过蠕虫,向其好友发送同一短暂性XSS连接.)- p2 N1 }; ]9 m" t
1 G! V" W; o1 S# E, X- I2 b5 n2:受害用户在登陆状态中,观看了存在XSS的问题页面,JS执行,并植入XSS蠕虫代码到该用户帐户中,且通过搜索好友等方法,传播给其他用户.即复制感染过程.(在论坛或者回复类型页面中传播XSS蠕虫,只要保证每页面同时存在2个或者以上蠕虫,就可以保证蠕虫不会被增加的数据覆盖.)6 q4 n, ^" z6 w3 C3 o" R% v4 K6 z
3 B! F+ v6 @. t7 ~$ k; L综上所述,结合以上种种技巧,就可以创造我们自己的XSS蠕虫了.在我们的蠕虫里,我们可以添加截取屏幕功能,DDOS功能,可以判断客户端浏览器的版本,读取并且发送客户端的本地文件~ 7 D: N# g$ y# R }, B( v/ F9 i9 o - R @/ w4 h. r7 _9 O; |' ? Q6 {- g9 v6 n) z5 Y5 Z) U8 a
