这只鸽子建议:诡计之后,贴日志求助的日子就要结束了!做好系统的基础安全防护,是每个用户的头等大事。“基本安全保护”不仅仅是打几个补丁的问题。还需要熟悉一两款性能良好的安全软件的使用。不然中招后,你自己也省心!
这只鸽子的密钥是c:\ windows \ winlogon.dll。如果您试图阻止这个dll的加载和运行,所有的pigeon文件都可以在图1中看到。
这只鸽子的钥匙是这个c:\ windows \ winlogon.dll。
如果c:\windows\winlogon.dll被SSM禁止加载运行,那么鸽子的所有文件都是可见的。
这是一只拴在Movgear.exe的灰鸽子(Movgear.exe样本来自保安12km)。winlogon.exe的MD5值为2 de 9 f 62 C2 b 405 e 16 CB 66773747 cf 0 f 2d。
1.winlogon.exe从Movgear.exe提取出来植入系统后,autoruns、HijackThis、SREng的日志都没有异常发现。
winlogon.exe公布的文件有:
1、c:\windows\winlogon.exe
2、c:\windows\winlogon.dll
3、c:\windows\winlogonKey.dll
这两个dll插入到IE浏览器进程中。
即使不打开ie浏览器,在冰剑的进程列表中仍然可以看到iexplore.exe。
C:\windows\winlogonKey.dll动态跟踪所有应用程序进程(一旦打开,立即插入。)
注意:即使显示隐藏文件,灰鸽发布的三个文件用WINDOWS资源管理器也看不到。只有用冰剑才能看到。
其次,注册表的变化包括:
1.在HKEY _本地_机器\系统\当前控制集\服务中
添加:winlogon.exe(指向c:\windows\winlogon.exe)
2.在HKEY _用户\。默认\软件\ Microsoft \ internet explorer \ extensions \ cmd mapping
添加:
{ 92780 b25-18CC-41 c8-B9BE-3c 9c 571 a 8263 } '=dword:00002002

3.在HKEY _用户\。默认\软件\ Microsoft \ Internet连接向导
加法:'已完成'=十六进制:01,00,00,00
4.在HKEY _用户\。默认\软件\ Microsoft \ Internet Explorer \工具栏\ WebBrowser
添加:

5、在HKEY _用户\。默认\软件\ Microsoft \ Windows \当前版本\ Explorer \ CabinetState
添加:' Settings'=hex:0c,00,02,00,0a,01,ef,75,60,00,00,00
6、在HKEY _用户\。默认\软件\ Microsoft \ Windows \当前版本\ Ext \ Stats \
添加:
{ 0055 c089-8582-441 b-A0BF-17b 458 C2 a3 A8 }

7、在HKEY _用户\。默认\软件\ Microsoft \ Windows \当前版本\资源管理器\菜单\收藏夹\链接
添加:' Order '=十六进制:08,00,00,00,02,00,00,00,00,01,00,00,00,00,00,00,00,00,00,00,00
三、进行上述观察后,重启系统。
重启后,卡巴斯基报警(我的卡巴斯基为启动加载):发现灰鸽子。但卡巴斯基仅仅将c:\windows\winlogon.dll删除;c:\windows\winlogon.exe和c:\windows\winlogonKey.dll卡巴斯基并不报毒。汗!卡巴斯基越来越不争气了另外发现其winlogonKey.log文件。文件内容为:
#?4?74;
四、查杀流程:
1、打开注册表编辑器,展开HKEY _ LOCAL _ MACHINE \ SYSTEM \ current control set \ Services
删除灰鸽子的服务项:winlogon.exe
2、重启系统。用冰剑找到并删除鸽子释放的那三个文件。
4、清理注册表(删除鸽子添加的注册表项)。
