Copy link

不理解为什么
第三方网站 用<embed 方式加载 目标网站的jpg,运行的flash是以目标网站的域下发起 get请求的

你应该是理解错了, 是不是以为把swf传到其他服务器上

比如访问:1.qq.com/crossdomain.xml
内容如下:
<cross-domain-policy> <allow-access-from domain="*.qq.com"/> <allow-access-from domain="*.gtimg.com"/> </cross-domain-policy>

1.qq.com内容就可以进行flash劫持.

条件:
1.需要在*.qq.com,*.gtimg.com 寻找一个上传图片的功能 , 上传swf文件 , 可以使用jpg格式
2.把payload放在任意一个网站里面文件为html,访问即可被劫持.ie默认支持flash
