Ethical Hacking – Sniffing focuses on one of the most fundamental yet powerful techniques used by attackers to intercept, analyze, and manipulate network traffic. Sniffing attacks allow hackers to capture sensitive data such as usernames, passwords, session cookies, and confidential communications as they travel across a network.

This course explains how sniffing works, how attackers exploit network weaknesses, and how organizations can defend against traffic interception attacks.

What You’ll Learn

How network sniffing works at the packet level
Why switched networks are still vulnerable
Common sniffing-based attacks used in real environments
DHCP, MAC, and DNS-based network manipulation techniques
Effective countermeasures to prevent sniffing attacks

Course Modules

1. Sniffing – It’s Not the Cold Season

What sniffing is and why attackers use it
Active vs passive sniffing
Hub vs switch behavior and traffic visibility
Sniffing encrypted vs unencrypted traffic

2. DHCP Assaults

How DHCP works in a network
DHCP starvation attacks
Rogue DHCP servers
Man-in-the-Middle attacks using DHCP manipulation

3. Big-MAC Attacks

Understanding MAC addresses and CAM tables
MAC flooding attacks
Forcing switches to behave like hubs
Intercepting traffic on switched networks

4. DNS Poisoning

How DNS resolution works
DNS spoofing and cache poisoning attacks
Redirecting users to malicious websites
Credential harvesting using fake DNS responses

5. DNS Poisoning (Advanced Scenarios)

Local vs remote DNS poisoning
ARP poisoning combined with DNS attacks
Persistent DNS manipulation techniques
Impact on users, applications, and enterprises

6. Countermeasures

Using HTTPS, TLS, and encrypted protocols
DHCP snooping and port security
Dynamic ARP Inspection (DAI)
Secure DNS configurations (DNSSEC)
Network monitoring and intrusion detection

Who This Course Is For

Ethical hacking and penetration testing students
Network security professionals
SOC analysts and blue team members
IT administrators securing enterprise networks

Why Sniffing Attacks Matter

Sniffing attacks often go unnoticed because they don’t always disrupt systems. Attackers can silently collect credentials, sessions, and sensitive data without triggering alarms.

Understanding sniffing is critical to:

Protect user credentials and sessions
Secure internal and public networks
Prevent Man-in-the-Middle attacks
Detect hidden attackers inside the network
