Phishing Attack Basics

Targeting a Specific Individual

• Example target: Bernard Hackwell, CEO of Network Chuck Coffee.
• Objective: Gain access to his LinkedIn credentials.

Step 1: Setting Up a Phishing Website

• Create a fake LinkedIn page to harvest credentials.
• Use social engineering to trick the target into entering their username and password.
• Credential Harvesting: Listening for credentials entered on the fake site.

Tools & Setup

• Operating system: Kali Linux (hacking-focused Linux distribution).
• Use the command git clone to download the Black Eye tool for phishing.
• Set up the phishing page to look legitimate.
• Use ngrok for tunneling if necessary (requires free account setup).

Step 2: Sending Phishing Email

• Craft a phishing email that appears to be from LinkedIn.
• Example message: "You have an important message from a colleague, click here to log in."
• Phishing emails can also be sent via text (smishing) or phone calls (vishing).

Types of Phishing Attacks

Spear Phishing

• Targeting specific individuals (e.g., Bernard).
• More personalized approach compared to general phishing.

Whaling

• Targeting high-profile individuals like CEOs (e.g., Bernard).

Sending the Attack

• Use Social Engineering Toolkit (SET) in Kali Linux for crafting spear phishing emails.
• Keep the attack focused on one individual to increase effectiveness.
• After the target clicks the link, credentials are captured without their knowledge.

Advanced Techniques

• Use malicious files disguised as legitimate documents to trick the target.
• Discussed DNS Poisoning and Pharming: Redirecting legitimate requests to malicious sites.

Prevention Strategies

Awareness

• Importance of awareness and training to avoid phishing attacks.
• Utilize good spam filters to catch unsolicited emails.

Best Practices

• Avoid clicking on links in emails or texts; verify the source first.
• Educate family and friends about the risks of phishing.
• Be cautious of emotional manipulation in phishing emails (e.g., urgency).

Conclusion

• Phishing attacks are simple but can be effective against untrained individuals.
• Always seek permission before testing phishing techniques.
• Encourage learning and awareness to combat such attacks.
