Hands-on network attack labs and defensive countermeasures.
MAC Flooding using macof
Completed
Lab demonstrating MAC flooding attacks on network switches. Illustrates how attackers can compromise switch security and the importance of network defense mechanisms.
MAC FloodingmacofNetwork AttacksSwitch Security
What I did
Generated a high volume of spoofed MAC addresses with macof to overflow the CAM table.
Observed switch behavior degradation and traffic leakage to unintended ports.
Documented mitigations: port security, static MAC entries, and VLAN segmentation.
Performing ARP Poisoning using arpspoof
Completed
Practical lab on executing ARP poisoning attacks to intercept network traffic. Shows attack techniques and helps understand defensive measures against man-in-the-middle attacks.
ARP PoisoningarpspoofMITMNetwork Attacks
What I did
Used arpspoof to send forged ARP replies and redirect traffic through the attacker host.
Captured and inspected intercepted traffic to demonstrate the MITM risk.
Lab demonstrating DHCP starvation attacks using the Yersinia tool. Explores denial-of-service attacks on network infrastructure and mitigation strategies.
DHCP StarvationYersiniaDoSNetwork Attacks
What I did
Launched a DHCP starvation attack to exhaust the address pool with Yersinia.
Observed legitimate clients failing to obtain leases during the attack.
Documented mitigations: DHCP snooping, rate limiting, and trusted port configuration.
