In active sniffing, ARP traffic is actively injected into a LAN to sniff around a switched network and capture its traffic.
1. Perform mac flooding using macof
MAC flooding is a technique used to compromise the security of network switches that connect network segments or network devices. Attackers use the MAC flooding technique to force a switch to act as a hub, so they can easily sniff the traffic.
sudo macof -i ens33 -n 10
-i interface
-n number of packets to send
targeting an IP address
2. Perform a DHCP Starvation Attack using Yersinia
In a DHCP starvation attack, an attacker floods the DHCP server by sending a large number of DHCP requests and uses all available IP addresses that the DHCP server can issue. As a result, the server cannot issue any more IP addresses, leading to a Denial-of-Service (DoS) attack.
Start the Yersinia in an interactive mode.
press h for help, q to exit help
F2 to open DHCP attack mode. DHCP fields will be shown in the bottom
press x to list attack options and the type 1 to conduct DHCP starvation attack.
