靶场复现 - VulnStack 0x02

之前都是似懂非懂,迷迷糊糊,全靠工具和试错才成功,这一次打算好好理理这部分的学习框架

描述

红队实战系列，主要以真实企业环境为实例搭建一系列靶场，通过练习、视频教程、博客三位一体学习。本次红队环境主要Access Token利用、WMI利用、域漏洞利用SMB relay，EWS relay，PTT(PTC)，MS14-068，GPP，SPN利用、黄金票据/白银票据/Sid History/MOF等攻防技术。关于靶场统一登录密码：1qaz@WSX

  1. Bypass UAC
  2. Windows系统NTLM获取（理论知识：Windows认证）
  3. Access Token利用（MSSQL利用）
  4. WMI利用
  5. 网页代理，二层代理，特殊协议代理（DNS，ICMP）
  6. 域内信息收集
  7. 域漏洞利用：SMB relay，EWS relay，PTT(PTC)，MS14-068，GPP，SPN利用
  8. 域凭证收集
  9. 后门技术（黄金票据/白银票据/Sid History/MOF）

环境说明

内网网段：10.10.10.1/24

DMZ网段：192.168.111.1/24

测试机地址：192.168.111.1（Windows），192.168.111.11（Linux）

防火墙策略（策略设置过后，测试机只能访问192段地址，模拟公网访问）：

之后go mod init test && go build

但当用上面的思路来传后门时,会发现无法下载。即使后门程序可以绕过检测(确实过了静态),但其下载过程还是会被检测,检测警告⚠分成cmd.exe执行、对未知链接访问、certutil下载过程.

这样的话,payload执行过程中不允许cmd执行,不能使用对未知链接访问和用certutil下载.

我们试试先用powershell试试,也还是被检测到。

image-20210304102619662

在terminal 直接使用wmic process call create "calc"也还是被检测到

但其他师傅用 CVE-2021-2109 可以绕过

个人估计360是对com.bea.core.repackaged.springframework.context.support.FileSystemXmlApplicationContext利用链有查杀,而对CVE-2021-2109还没有,但我估计之后应该也有。

这个特别玄学,一会又变成了de1ay/de1ay权限

之后用同样的方法对cs生成的payload.c生成免杀exe,用BP发包执行C:/Oracle/Middleware/user_projects/domains/base_domain/cs.exe,这样将获得Administrator权限

小trike: 对于设备比较差的机子,可以通过爆破的方法,让WAF有时无法检测,从而使一些后门成为漏网之鱼,但要注意时间

image-20210305103927701

但这种方法也有问题,但你第二次使用Java 开启线程时,会被360拦截。

之后再上线CS

image-20210305121312648

JMeterPreter 居然没有被360检测到,香,真滴香,有空看看哥斯拉是怎么实现的

后渗透 [开360]

Proxy

常用的方法有上传socks程序或利用框架,我这边选择CobaltSrikt开启代理

1
beacon> socks 7475

image-20210305125139336

同时可以用MSF链接代理

set Proxies socks4:127.0.0.1:7475
set ReverseAllowProxy true

信息收集

基本命令

1、获取当前组的计算机名(一般remark有Dc可能是域控)：

1
net view

2、查看所有域

1
net view /domain

3、从计算机名获取ipv4地址

1
ping -n 1 DC1 -4

4、查看域中的用户名

1
2
dsquery user
net user /domain

5、查询域组名称

1
net group /domain

6、查询域管理员

1
net group "Domain Admins" /domain

7、添加域管理员账号

1
2
3
4
添加普通域用户 
net user lemon iam@L3m0n /add /domain 
将普通域用户提升为域管理员 
net group "Domain Admins" lemon /add /domain

8、查看当前计算机名，全名，用户名，系统版本，工作站域，登陆域

1
net config Workstation

9、查看域控制器(多域控制器的时候,而且只能用在域控制器上)

1
net group "Domain controllers

10、查询所有计算机名称

1
2
3
dsquery computer 
下面这条查询的时候,域控不会列出 
net group "Domain Computers" /domain

11、net命令

①映射磁盘到本地

1
net use z: \\dc01\sysvol

②查看共享

1
net view \\192.168.0.1

③开启一个共享名为app$，在d:\config

1
net share app$=d:\config

12、跟踪路由

1
tracert 8.8.8.8

定位域控

1、查看域时间及域服务器的名

1
net time /domain

copy

2、ldap

1
Nslookup -type=SRV _ldap._tcp.

copy

3、通过ipconfig配置查找dns地址

1
ipconfig/all

copy

4、查询域控

1
net group "Domain Controllers" /domain

查看域网络信息

提权与获取密码

MSF - 脚本提权 [失败]

开启360情况下内核溢出基本不行

因为本地开启360,无法使用getsystem

1
2
3
use post/multi/recon/local_exploit_suggester
set session 2 
run

虽然推荐的也都被360拦住。

Cobaltstrike

但在cobaltstrike(用户为 de1ay\administrator )上,可以直接hashdump和minikatz,

image-20210305132909994

很奇怪的一点是,de1ay\administrator 并没有域用户权限,对CobaltStrike具体如何做的感到好奇

有可能也是用来 Access Token

image-20210305133740524

本机管理员如下:
image-20210305134051991

最终获取的密码和hash如下:

image-20210305143203665

内核溢出提权在360开启环境下,会因为创建木马直接杀,甚至原来的session也会被干掉。

域内的话可以添加域用户并添加进域管理组进行敏感操作
add_user test fe1w0@WSX -h 10.10.10.10
add_group_user "Domain Admins" fe1w0 -h 10.10.10.10

为什么内核提权需要上传执行文件并且是怎么做到的,能否自己做免杀后再执行。还有Access Token 是如何窃取的。

对360防护的总结如下:

  • 对于下载操作和远程执行、计划等这些操作,360会杀,但不会拦截读写操作。
  • 对powershell检测严格
  • 当利用java漏洞开启新进程(CMD)时(如 cve- 2020-14883 && CVE-2021-2109 )时,有可能会被检测

对于cmd /c calc 这些操作,360还是运行执行的

  • 对于免杀木马,执行操作时,若不是高危操作且被360警告的情况,木马会警告而不会被删
  • 对于CS和MSF生成的木马程序(若内核溢出提权等这些需要下载木马才执行的操作),360会直接杀掉生成木马,且会将上一级调用的程序也杀死。
  • 针对ms17-010,360有防护

但有师傅也有说,可以用ms17-010_cmd来执行

  • Access Token 窃取,360不杀。
  • 假定从web机开始发起,对于普通的横向转移(如添加远程任务这些),安装在WEB机上的360一般都会检测到,但CS用psexec进行Pass The Hash不会被检查到(此处产生一个问题,CS是如何用Psexec,且不被检测到),且被攻击机上的360也不会检测到。

windows 白名单 程序

  • 哥斯拉上的 JMeterpreter进行反弹时,不会被360检测到,此外冰蝎也是不会被检测到。
  • MSF: run vnc 会下载一个程序,若有360,一旦开启,木马直接被杀,所以千万不要手欠,截截桌面还是可行的。

此外还有一点比较迷惑,当MSF拥有NT Administrator 权限或CS拥有 de1ay/Administrator时,是如何做到dumphash和minikatz而不被360警告

差点忘了,当进入WEB机上后,可以将360强杀(可惜这次没有找到相关资料,用WMIC关闭360进程时显示成功,但很快又有新的360进程开启)。

之前,半凉一夏师傅在b站演示过强杀360,可惜的是没有说具体思路。
