Technitium MAC Address Changer allows
you to change (spoof) Media Access Control (MAC) Address of your Network Interface
Card (NIC) irrespective to your NIC manufacturer or its driver.
It has
a very simple user interface and provides ample information regarding
each NIC in the machine. Every NIC has a MAC address hard coded in its
circuit by the manufacturer. This hard coded MAC address is used by windows
drivers to access Ethernet Network (LAN). This tool can set a new MAC
address to your NIC, bypassing the original hard coded MAC address. Technitium
MAC Address Changer is a must tool in every security professionals tool
box.
