![]() ![]() MAC filtering - Most Airlines or Hotels, automatically disconnect the Internet on the devices after some time. So, if you want to be anonymous on a public WiFi then change your MAC address make sense. But other devices on your Local Area Network can. Privacy - When you connect to the internet, the web server can not see your MAC address. Well, there are several reasons to change the MAC address. Related: 10 Steps to Secure Your Wi-Fi Network From Hackers Now, even though the MAC addresses are hardwired in your network card, You can still change it with the help of special tools or commands. Making that into a useful tool is left as an exercise to the reader.A typical MAC address looks something like this - EB-52-02-F0-2E-06 and since it’s unique for each device, it’s often used to identify different devices on the network. This tends to make me think that these registry settings would work (not that any of them are helpful to you).ĭumping Windows kernel pool allocations is above my pay grade, but I suspect that if you were to figure out what the bridge.sys pool tag was (I suspect it's Brdg) and dump any pool allocations it makes you'd find the adjacency table in one of those allocations. It's interesting to note that the names of the registry parameters specified for the Windows CE network bridge driver are present in the Windows 7 bridge.sys driver. Searching Microsoft's website for any command-line (or otherwise) tools that deal with the network bridge (aside from the paltry support in netsh) isn't turning up anything for me. I think you're out-of-luck, from a documented and supported command-line perspective. (This ASCII text string embedded in the binary is a nice touch, though: Without specific written consent from Microsoft, it is illegal to reverse engineer, debug or change this binary.) Without access to the bridge.sys source code it's difficult to say anything with certainty, but some cursory sniffing around the binary doesn't show any exposed APIs that would be helpful in dumping the layer 2 adjacency table. The Network Bridge functionality appears to be wholly implemented (at least in Windows 7) by the bridge.sys driver. ![]()
