There are a ton of different tools and ways to change your MAC address, let alone simply doing it manually. Here’s a few I’ve accumulated notes about over the past 6 months.
Macshift is a standalone C++ tool run via the command line. Does what it should do!
Technitium is probably the Mercedes of mac changers, sporting tons of information in the GUI and also being scriptable.
Smac is also a old favorite I see mentioned a lot, but the eval version is slightly limited. For such a small tool, I just don’t believe in shelling out money for it.
Speaking of Windows tools, Wirelesskeyview is a quick .exe (no installation required) that will pull out wireless network keys and display them for you. I’m sure these are just stored in a registry entry somewhere and, if encrypted at all, are like just rot13, but still this tool makes life easy.
Heck, I’ll stick with Windows for this whole post. The Windows firewall is still daunting to manage or maintain for most people, even those of us who are comfortable with firewalls! This kb article from Microsoft is surprisingly detailed. I especially like the last section on enabling and checking the logging of dropped packets. Combine this with a tail program and it might turn a spare WinXP box into a network tripwire-like device.
Yesterday I posted a few OS fingerprinting tools. I missed one I had in my box called Satori. This looks like a quick effort that may not be regularly updated, but is a passive OS fingerprinter for a few OS types. I’ve not had a chance to try this out yet as my Windows machines at home are limited, but it might be fun to try, even if it doesn’t make any toolboxes. A related paper on the site is also interesting.
