I did a fresh install of Ubuntu 11.04 on my desktop computer last saturday and, as I was having some problems with my internet connection, I had to reset my wireless router and reconfigure it.
Turns out, as my nickname suggests, I'm not very bright, and I forgot to confirm my Wi-Fi security preferences, which were supposed to allow wireless access only to my laptop's MAC address. Just 10 minutes ago I realized that the Wi-Fi led on my router was blinking quite a lot.
Now, my question is: What are the odds that my files (those in my desktop Ubuntu) have been remotely accessed by the ruffian who plundered into my connection? And what can I do to verify whether it happened or not?
I have changed very little the oringinal install: I installed the restricted extras and SSH, in order to access my desktop files from my Xubuntu laptop. I've checked the SSH log in my Ubuntu desktop and I can only find my laptop's IP there.
I don't know how the VNC setup works on Ubuntu, but I didn't enable it, and I just tried to make a VNC connection from my laptop and access was denied.
I have not enabled Windows-style file sharing, and I just tried to open a folder from laptop and access was denied.
My Ubuntu session starts only with password.
What else should I look for?
Thanks in advance and sorry for the rambling.
(and don't worry, I have confirmed the MAC address restriction in my router now, the Wi-Fi les stopped blinking).
