What can I do with a leech's MAC address? - Page 3

post #21 of 55
have you considered changing you network features so only your MAC address can connect to the network as well? This will limit it so he can only hack you while you are currently online surfing the wifi I believe because what they do sometimes is use your own MAC address to spoof the network into de-authenticating itself and then they capture the re-connection "wireless handshake" and start cracking your password


these days people can upload your wireless handshakes to websites like Amazon cloud that will distribute the computing across many work stations and crack the passwords in a fraction of the time it previously took. In addition, as stated before, GPU hardware acceleration has greatly increased the speed of password cracking so your best bet would to indeed make a ridiculous password like yo stated


make sure you go through your network setting because this guy could have gone into your network settings on your router and created an exception for his IP / MAc Address so he can always get on your internet even if you changed your password.

Not so much, in fact.

If Mr. X cracked Mr. TwoCables' wireless security, and Mr. TwoCables is also connected via wireless, Mr. X would be able to "listen in" on everything Mr. TwoCables is doing on the network, including URLs visited, clear-text usernames and passwords, etc...

Anyways, it's a very unwanted situation to be in. And I hope it doens't happen to you again.

My sig rig is wired to the wireless router. The only thing that uses the wireless router for its wireless access is the laptop which is not mine and which I never use.

So what I did tonight (or earlier this morning, really) is I enabled the only MAC address filtering I have: "Wireless MAC Filter". I put the laptop's MAC address in there and while I was doing this, I saw a foreign MAC address. So I went into "Access Restrictions" and blocked it for good measure. biggrin.gif

I can't do anything with my sig rig's MAC address.

Yeah, my new password is awesome. lol It looks similar to this:
Code:

My router's password looks similar to this:

I went through every last corner of the firmware when I finished: nothing has changed. smile.gif

It's funny because this makes me wonder just how long this person has been getting free internet access through my router. I mean it makes me wonder if it was just dumb luck that he decided to access OCN while I was not home (and while my PC was off).

If it keeps continuing, and if it is possible for you, it might be interesting to turn off the wireless for a while and switch to wired. He can't pick up on a signal that isn't there. smile.gif

PS-I'm not leeching your network. tongue.gif

A slightly less technical defence would be to turn off your router when you're not using it.

Leech and Boyboyd:

I can't turn it off because it's providing access to a laptop that's not mine and which I never use. So if I do that, then this person will be like "Hey, while you were gone, the internet wasn't working. Can you fix it?"

lol I'd love to meet the guy who is more advanced than I am because damn: as far as I know, I'm the only one in this area who knows anything about computers at all - and my router doesn't have a large range on it at all.

Are you using dd-wrt firmware? It would give you more control over your router.

How do people find dissabled ssid broadcasting routers? Mine has been dissabled from the begining so people in my complex cannot see my connection.
