This indicates that that the owner of the 192.168.0.106 IP address is most likely the attacker. When you connect to the internet, you typically first connect to an Internet Service Provider (ISP) in order to connect to another website. When a hacker sends a false ARP message over a local network, they are then able to link to your MAC address with the IP address of a legitimate computer or server. Mapping the machines with sets of static IP and MAC addresses helps to prevent spoofing attacks, because the machines can ignore ARP replies. What is a Cross-site scripting attack and how to prevent it? ARP poisoning is very effective against both wireless and wired local networks. Address Resolution Protocol (ARP) poisoning is an attack that involves sending spoofed ARP messages over a local area network. These attacks attempt to divert traffic from its originally intended host to an attacker instead. You should also enable any ARP spoofing prevention options and stop any endpoint processes that send suspicious ARP traffic. * Indusface is now Apptrana, Overcoming Network Security Service and Support Challenges in India. As long as your network administrator is quick to act once alerted, you can generally shut down these attacks before much damage is done.
