That article seems to talk on discovering our own mac address, see the bold: how-do-i-find-out-the-mac-address-of-my-linux-or-freebsd-system

What I'm specifically interested is to know whether the folling scenario is possible, and if it is, how:

A car pulls over and parks in front of my house so the driver can go to the grocery store that is across the street. There's another person on the car and he/she stays there with his/her notebook. This person sees my wi-fi and tries to connect to it, but there's a strong password preventing the connection and also a MAC filter. How would this person know the MAC addresses on the filter list so he/she could clone it? Would it be easy to clone the address in this scenario?

Done already

I use syslinux instead of GRUB but I'm looking forward to know if a syslinux password is necessary since I encrypt the whole drive.

Well my machine does connect to the router via cable, is that what you mean here?
My machine falls into both cases: I use it for work and for home use as well (e-Mail; Steam; VLC; Youtube; you get the picture)

I see, my bad Didn't know it's possible.

So I responded to those questions, one by one, with my thoughts and personal experiences. Now you are presenting yourself as a security genious that knows it all.
That's wasn't my intention. Forgive me if that's the image you got from me.

I didn't know it would be that easy to get the MAC addresses on the network, sorry.

Thanks.

1) If you are that concerned, it would be best to not use wireless and set up your home network with only wired connections.
2) Worrying about such a scenario assumes you believe people with the knowhow would be interested in you and your files. Are you really important enough to get the attention of such people?

Can't, he bought the Router so they could use their cellphones and tablets. The only computer connect through cable is mine.

If I were, would I openly tell everyone here?

Code:

Sadly so yes but I don't know how they do it-

I met a mathematical genius in 2000 and he was able to solve any combination of numbers on this earth in any form (basic math, calculus, Algeria, etc.) and he cracked the code on my system.

FWIW, Amarildo a IT Tech that I communicate with made it clear to me that it's pretty hard to break the WPA password and encryption but he did say that it's not impossible.

As Randicus Draco Albus mentioned if your that concerned; switching to a wired connection will most likely put your mind at ease.

Easiest way is to use a security penetration Linux Distro. Kali. Backtrack. etc. The tools you need are all there.

Since you really seem to want to know the technical steps to do this, here's a tutorial that illustrates one way to accomplish the task (if you can tolerate the music playing during the video):

You might want to check out http://sectools.org/ to become more familiar with the tools of the trade.

I believe the majority of these tools are available on the Network Security Toolkit Linux distro. http://www.networksecuritytoolkit.org/nst/index.html
