- [Instructor] On a local area network,…a host is identified by its MAC address.…If we spoof the MAC address,…an attacker can intercept traffic.…If the MAC address is spoofed, the victim may be…well unaware that anything has taken place,…and the attacker can sniff all the traffic…that was designed to go to the victim.…But how do we spoof a MAC address?…Well, we need to change it.…I'm in a Windows operating system.…Now, there are some software tools that you can use…to change a MAC address, however, some of them are outdated…and they don't work with modern operating systems.…
Let's take a look at a couple ways…you can change your MAC address.…I want to go to the Device Manager.…Once in the Device Manager,…I'm going to go to Network Adapters.…I found the network adapter,…and I'll right click and look for Properties.…Now I'll go to Advanced.…Now here it says Locally Administered Address.…A network adapter has a number…of alternate naming convention.…They could go by network address, adapter address,…MAC address, physical address, Ethernet address,…
