MacBook Security - Who is this?

[shouldberunning]

I know there's probably a Security thread on here somewhere but I thought this might be specific to MacBook.

I found two computers attached to me somehow but I don't know how. My router is locked down and I checked the MAC addresses of everyone connected and it all checked out.

They showed up under the "Shared" heading in the left column of finder.

I could not connect to either of them or get any info on them.

Turning off BlueTooth didn't kill the connection.

Any ideas on how they were connecting to me.

Are they the other people connected on your network that you checked the mac address of?

No. The MAC addresses are accounted for. These 2 intruders do not show MAC addresses in the router.

This makes me think that the router is not part of the picture. But rather an Airport issue. Maybe my MacBook is just seeing there Wireless signals from their laptops.

I know you said your router is locked down, but what encryption scheme are you using?

I just hope you're not running WEP with a really long key and calling that "locked down," because it's far from it. WPA/WPA2 AES will keep virtually everyone out.

It's probably just other PCs that are on the same subnet as you are on with your ISP.

 

[chill.]

can you give more information on your isp? do you have your own personal connection or do you maybe share with your building or live in a dorm/apartment?

WPA all the way.

Cable ISP. Apartment building. I can see tons of routers around me.

I'm not sure what else I can say about my ISP. I don't know much about that end of things.

Check to see if you have "Back To My Mac" turned on. It might just be other Macs. Also what kind of router is it ?

Relaunch Finder and see if they disappear. If you take your MacBook around with you a lot and connect to different networks sometimes the Finder is a bit slow to forget the computers that it has recently seen.
