Cyber-security---Task-2

Overview

This project demonstrates phishing email analysis techniques to identify and understand email-based threats. It's an educational tool to learn about phishing tactics and email security.

⚠️ IMPORTANT: This is for educational purposes only. Never interact with real phishing emails unless in a controlled environment.

Objective

Identify phishing characteristics in suspicious email samples and understand common attack vectors.

Tools Used

• Python 3 - Email header analysis automation
• Online Header Analyzers - MXToolbox, Google Admin Toolbox
• Text Editors - To examine email source code

What's Included

• Sample phishing emails (.eml format)
• Python script for automated analysis
• Detailed phishing analysis reports
• Interview questions with answers

Quick Start

Analyze Sample Emails

# Run the analysis script
python3 email_analyzer.py samples/phishing_sample_1.eml

# Or analyze all samples
python3 email_analyzer.py samples/*.eml

Manual Analysis Steps

1. Examine the sender's email address
2. Check email headers for discrepancies
3. Identify suspicious links or attachments
4. Look for urgent language or threats
5. Check for spelling/grammar errors
6. Verify mismatched URLs

Phishing Indicators Checklist

✅ Sender Address:

• Mismatched or spoofed domain
• Random characters or numbers
• Free email service (Gmail, Yahoo) for business

✅ Email Headers:

• Originating IP doesn't match claimed sender
• Multiple "Received" hops through suspicious servers
• SPF/DKIM/DMARC failures

✅ Email Body:

• Urgent or threatening language
• Requests for personal/financial information
• Spelling and grammar errors
• Generic greetings ("Dear Customer")

✅ Links and URLs:

• Mismatched display text vs. actual URL
• Shortened URLs (bit.ly, tinyurl)
• Suspicious domains (typosquatting)
• Non-HTTPS for sensitive actions

✅ Attachments:

• Unexpected attachments
• Executable files (.exe, .scr, .bat)
• Office docs with macros
• Compressed files (.zip, .rar)

Common Phishing Types

1. Spear Phishing - Targeted attacks on specific individuals
2. Whaling - Attacks targeting executives
3. Clone Phishing - Legitimate email replicated with malicious content
4. Business Email Compromise (BEC) - Impersonating company executives
5. Vishing - Voice phishing via phone calls
6. Smishing - SMS/text message phishing

Red Flags Examples

Suspicious Sender:

Display: "PayPal Security"
Actual: security-paypal@gmail.com ❌

Mismatched URL:

Display text: "Click here to verify your account"
Actual link: http://paypa1.suspicious-site.ru ❌

Urgent Language:

"Your account will be suspended in 24 hours!"
"Immediate action required!"
"Unusual activity detected - verify now!"
