The target destination will be traced with each ???hops??? results displayed.
*Note: Remember that attackers will commonly trace a target to attempt to identify
the IP address before the target. This is probably a router.
*Note: Packit is a pretty good application for injecting ???spoofed??? IP/MAC addresses.
Attackers can use this tool for several reasons (i.e., verifying if egress/ingress
filtering is ???on??? on the routers, Man-in-the-Middle (MTM) attacks, Denial of Service
(DoS) attacks).

Lab 52: Spoof MAC Address
Altering the MAC Address: VMware Workstation
Prerequisites: None
Countermeasures: Firewall filters, vendor patches where applicable
Description: VMware Workstation is perfect for ???spoofing??? a MAC address
as the computer itself is completely virtual. Even though VMware Workstation
uses a configuration file to identify which MAC address will be
used, this file can be edited to the user??™s choice.
Procedure: Edit the appropriate file and turn on the virtual computer.
Verify the current MAC address with the ipconfig /all command.
In this example, the MAC address is 00:0c:29:a3:e4:40.
To manually assign a new static MAC address for a virtual machine, locate
and open with Notepad the virtual machines configuration file. The file ends
with a .vmx extension. In this example, the filename is Windows 2000
Server.vmx. For Linux machines the configuration file may end with the .
