A friend of mine was complaining about how he thinks somebody is tapped into his Wi-Fi.  I found out after looking into it, that he's using WEP...that's sad in itself.  Secondary he's got the default admin/password on his router admin page, not so smart, but not surprising.

When I logged into his router admin, I noticed several PC's named the same as his...I guess masking them on first glance?? Obviously the MAC addresses were different.  So I assume he is getting tapped for free Wi-Fi, but it got me to thinking:

1) What would you do to mask yourself in this scenario?
2) Was naming the PC the same as his an attempt to mask?

I'm new in this type of arena and now I'm interested like crazy and would love to put myself in their shoes to see the angle...like reverse engineering.  Let me know how you would cover your tracks or post links referencing this scene.

Thank you all in advance!!

You can also modify the MAC address to match another machine on the network.  This will hide your presence, making it look like a machine that the wifi owner believes is supposed to be on the network.  This also has the added bonus of bypassing MAC filtering, if configured.

Changing your mac address to something that doesn't look suspicious is one of the ways that you'd do it. You wouldn't want to change it to 00:11:22:33:44:55 because that'd stand out too much. Most home users, and corporate for that matter, don't keep track of mac addresses in their possession.

packet.Wire - Excellent.  I have a couple PC's I can play with.  Will do some research and see how it goes.  Thank you!
