一、NetBIOS信息
在我们和远程Windows2000/XP主机建立了空会话之后,我们就有权枚举系统里的各项NetBIOS信息了。当然在某些选项中需要较高的权利,不过我们只执行那些匿名用户可以获得的绝大多数系统信息。
时间:探测远程主机的当前日期和时间信息。它会返回一个数据结构,包括年,月,日,星期,时,分,秒等等。不过得到的是GMT标准时间,当然对于我们来说就应该换算为GMT 8:00了。由此可以判断出主机所在的时区信息。
操作系统指纹:探测远程主机的操作系统指纹信息。一共有三种级别的探测(100,101,102),我们使用的是101级,它会返回一个数据结构,可以获取远程主机的平台标识,服务器名称,操作系统的主次版本(Windows2000为5.0,WindowsXP为5.1,而最新操作系统Longhorn的版本为6.0),服务器类型(每台主机可能同时包含多种类型信息)和注释。
共享列表:探测远程主机的共享列表。我们可以获得一个数据结构指针,枚举远程主机的所有共享信息(隐藏的共享列表在内)。其中包括共享名称,类型与备注。类型可分为:磁盘驱动器,打印队列,通讯设备,进程间通讯与特殊设备。
用户列表: 探测远程主机的用户列表,返回一个数据结构指针,枚举所有用户信息。可获取用户名,全名,用户标识符,说明与标识信息。标识信息可以探测用户的访问权限。
本地组列表: 探测远程主机的本地组列表信息。枚举所有本地组信息,包含本地组名称和注释信息。
组列表: 探测远程主机的组列表信息。枚举所有的组信息,包括组名称,注释,组标识符与属性。在此基础上,我们可以枚举组内的所有用户信息。
组用户列表: 探测特定组内的用户信息。我们可以获得组内所有用户的名称。当我门获得了所有的用户列表,下一步就应该很清楚了,那就是挂一个字典进行破解了。
传输协议列表: 探测远程主机的传输协议信息,枚举所有的传输列表。可以获得每个传输协议的名称,地址,网络地址和当前与本传输协议连接的用户数目。
会话列表: 探测远程主机的当前会话列表。枚举每个会话的相关信息,包括客户端主机的名称,当前用户的名称,活动时间和空闲时间。这可以帮助我们了解远程主机用户的喜好等等。
2. 撤消空会话
WNetCancelConnection2(ipc,0,TRUE);
//ipc为TCHAR的指针,我们可以这样获得:
//swprintf(ipc,_T("\\\\%s\\ipc$"),argv[1]),argv[1]为主机名或地址;
3. 探测主机时间
nStatus=NetRemoteTOD(server,(PBYTE*)&pBuf);
//参数server为主机的名称或地址;
//pBuf为TIME_OF_DAY_INFO数据结构的指针;
//nStatus为NET_API_STATUS成员;
4. 探测操作系统指纹
NetServerGetInfo(server,dwLevel,(PBYTE *)&pBuf);
//dwLevel为等级数,我们选择的是101级;
//pBuf是SERVER_INFO_101数据结构的指针;
5. 探测共享列表
NetShareEnum(server,dwLevel,(PBYTE *)&pBuf,MAX_PREFERRED_LENGTH,&er,&tr,&resume);
//dwLevel的等级数为1级;
//pBuf是SHARE_INFO_1数据结构的指针;
//MAX_PREFERRED_LENGTH指定返回数据的长度;
//er指明返回的实际可以枚举的成员数目;
//tr返回所有的成员数目;
//resume用于继续进行共享搜索;
6. 探测用户列表
NetQueryDisplayInformation(server,dwLevel,i,100,0xFFFFFFFF,&dwRec,(PVOID
*)&pBuf);
//dwLevel的等级数为1级;
//i为枚举的索引;
//dwRec返回获取的信息数目;
//pBuf为NET_DISPLAY_USER数据结构的指针;
7. 探测本地组列表
NetLocalGroupEnum(server,dwLevel,(PBYTE *)&pBuf,-1,&er,&tr,&resume);
//dwLevel的等级是1;
//pBuf返回LOCALGROUP_INFO_1数据结构的指针;
8. 探测组列表
NetQueryDisplayInformation(server,dwLevel,i,100,0xFFFFFFFF,&dwRec,(PVOID*)&pGBuf);
//dwLevel的等级为3;
//pGBuf返回NET_DISPLAY_GROUP的数据结构指针;
9. 探测组内的用户
NetGroupGetUsers(server,pGBuffer->grpi3_name,0,(PBYTE *)&pUBuf,MAX_PREFERRED_LENGTH,&er,&tr,&resume);
//pGBuffer->grpi3_name为组的名称;
//pUBuf返回GROUP_USERS_INFO_0数据结构的指针;
10.探测传输协议列表
NetServerTransportEnum(server,dwLevel,(PBYTE *)&pBuf,MAX_PREFERRED_LENGTH,&er,&tr,&resume);
//dwLevel的等级为0级;
//pBuf返回SERVER_TRANSPORT_INFO_0数据结构的指针;
11.探测会话列表
NetSessionEnum(server,pszClient,pszUser,dwLevel,(PBYTE *)&pBuf,MAX_PREFERRED_LENGTH,&er,&tr,&resume);
//pszClient指定客户的地址;
//pszUser指定用户名;
//dwLevel的等级是10级;
//pBuf返回SESSION_INFO_10数据结构的指针;
12.释放内存
NetApiBufferFree(pBuf);
//释放由系统分配的内存空间。
三、 如何防止NetBIOS信息的泄露
我们可以安装防火墙来禁止空会话的建立,或者我们可以在网络连接属性里禁用TCP/IP上的NetBIOS,当然也可以在IP安全策略里禁用445/tcp端口来实现。只要空会话不能成功建立,那就很难获得上面提到的各项信息了。
