SMAC Professional 2.7

SMAC is a powerful, yet an easytouse and intuitive Windows MAC Address Modifying Utility (MAC Address spoofing) which allows users to change MAC address for almost any NetworkInterface Cards (NIC) on the Windows VISTA, XP, 2003, and 2000 systems, regardless of whether the manufacturers allow this option or not. SMAC does not change the hardware burnedin MAC addresses. SMAC changes the "software based" MAC addresses, and the new MAC addresses you change will sustain from reboots. SMAC helps people to protect their privacy by hiding their real MAC Addresses in the widely available wifi Wireless Network. SMAC also helps Network and IT Security professionals to troubleshoot network problems, test Intrusion Detection / Prevention Systems (IDS/IPS,) test Incident Response plans, build highavailability solutions, recover (MAC Address based) software licenses, and etc…
SMAC is the first Windows MAC Address Modifying Utility (since 2002), and it is developed base on the extensive research of KLC Consulting, Inc. SMAC is continuous updated with the latest trend in the networking and security, as well as valuable customers wishes and feedbacks.
Benefits and Applications of spoofing MAC address:
Protect Personal and Individual Privacy. Many organizations track wired or wireless network users via their MAC Addresses… In addition, there are more and more WiFi Wireless connections available these days, and wireless network use MAC Addresses to communicate. Wireless network security and privacy is all about MAC Addresses!
Perform Security Vulnerability Testing, Penetration Testing on MAC Address based Authentication and Authorization Systems, i.e. Wireless Access Points. (Disclaimer: Authorization to perform these tests must be obtained from the system owner(s).)
Build "TRUE" Standby (offline) systems with the EXACT same ComputerName, IP, and MAC ADDRESSES as the Primary Systems. If Standby systems should be put online, NO arp table refresh is necessary, which eliminates extra downtime.
Some online Game Players (Gamers) require changing the MAC addresses to fix IP problems for some reason…
Build HighAvailability solutions. For example, some firewalls that run on multiport NIC’s (i.e. quad port NIC) require the same MAC address for every port.
Troubleshoot Network problems. Arp Tables, Routering, Switching, …
Troubleshoot system problems
Test network management tools
Test incident response procedures on simulated network problems
Test Intrusion Detection Systems (IDS), whether they are Host and Network Based IDS.
If for whatever reason you need to keep the same MAC address as your old NIC, but your old NIC failed…
Some software can ONLY be installed and run on the systems with predefined MAC address in the license file. If you need to install one of these software to another system with a different Network Interface Card (NIC) because your NIC is broken, SMAC will come handy. However, you are responsible to comply with the software vendor’s licensing agreement.
Some Cable Modem ISP’s assign IP addresses base on the PC’s MAC addresses. For whatever reason, if you need to swap 2 PC’s regularly to connect to the cable modem, it would be a lot easier to change the MAC addresses rather than to change Network Interface Card (NIC). (You need to check with your ISP and make sure you are not violating any service agreements.)
