HydrAttack PoC EMail Spoofer Module: Testing Domain Security Against Email Spoofing

The HydrAttack PoC eMail Spoofer Module is a powerful tool designed to evaluate the security posture of a domain against email spoofing attacks. It performs a series of steps to assess the vulnerability of a domain to email spoofing, including SPF and DMARC checks, spoofing attempts, and verification of email delivery. This module is particularly useful for security professionals looking to identify and mitigate potential risks associated with email spoofing.

You Should Know:

1. SPF & DMARC Check:

The module first verifies whether the target domain has SPF (Sender Policy Framework) and DMARC (Domain-based Message Authentication, Reporting, and Conformance) records configured. These records are crucial for preventing email spoofing.
Command to Check SPF Record:
```
dig +short txt example.com
```
Command to Check DMARC Record:
```
dig +short txt _dmarc.example.com
```

2. Spoofing Attempt:

If the domain lacks proper SPF and DMARC protections, the module spins up a web server and attempts to send spoofed emails from that domain.
Python Script to Send Spoofed Email:
```
import smtplib
from email.mime.text import MIMEText</li>
</ul>

sender = '[email protected]'
receiver = '[email protected]'
msg = MIMEText('This is a spoofed email.')
msg['Subject'] = 'Test Spoofed Email'
msg['From'] = sender
msg['To'] = receiver

with smtplib.SMTP('localhost', 2525) as server:
server.sendmail(sender, [receiver], msg.as_string())
```
3. Verification:
- The module checks the delivery of the spoofed email to assess the real-world risk of exploitation.
- Command to Check Email Headers:
```
cat /var/log/mail.log | grep '[email protected]'
```
4. Docker Setup:
- The module runs in a Docker container, making it easy to set up and use.
- Command to Start Docker Container:
```
docker run -it --rm hydrattack-poc-email-spoofer
```
5. Linux Commands for Email Security:
- Check Open Mail Relays:
```
nmap -p 25,465,587 --script smtp-open-relay.nse example.com
```
- Analyze Email Headers:
```
grep 'Received:' /var/log/mail.log
```
6. Windows Commands for Email Security:
- Check SPF Record:
```
Resolve-DnsName -Name example.com -Type TXT
```
- Check DMARC Record:
```
Resolve-DnsName -Name _dmarc.example.com -Type TXT
```
What Undercode Say:

Email spoofing remains a significant threat to organizations worldwide. The HydrAttack PoC eMail Spoofer Module provides a practical way to test and improve the security posture of your domain. By understanding and implementing SPF, DKIM, and DMARC records, you can significantly reduce the risk of email spoofing attacks. Additionally, regular security audits and penetration testing are essential to identify and mitigate potential vulnerabilities.

Expected Output:
- SPF Record Check Output:
```
"v=spf1 include:_spf.example.com ~all"
```
- DMARC Record Check Output:
```
"v=DMARC1; p=none; rua=mailto:[email protected]"
```
- Email Header Analysis Output:
```
Received: from mail.example.com (mail.example.com [192.0.2.1])
```
By following the steps and commands outlined above, you can effectively test and secure your domain against email spoofing attacks.
