I'm affraid I might have been hacked!!!
Recently I've been experiencing some strange behaviour on my mac. Maybe I'm being paranoid but I'm quite scared that someone may be accessing my mac and files.
Well my home network has my Mac, a PC with Win xp sp2, Using a belkin wireless modem/router to connect to my broadband line.
The PC is connected to the router physically and I use wireless for my mac. I have windows firewall enabled on the PC and OS X firewall also enabled and running in stealth mode - I do not have UDP blocking enabled, I also have my router's firewall enabled.
I do not have wireless encryption set up on the router but have mac address filtering enabled to allow only my mac and pc to connect to my home network.
I thought that this would be safe enough a setup considering how secure OS X is.
Anyway, my worry springs from 3 things I recently have been playing around with the sharing technologies in OS X mostly FTP and personal file sharing, etc. But I now have them all switched off. these past couple days i've noticed that;
1) My mac would not sleep when inactive according to my power management settings. I repaired permissions and restarted, it seemed to fix it.
2) All my widgets had been turned on, I did not do this.
3) The full keyboard access was enabled, I also did not enable this, and although it is possible that I accidently pressed Fn-ctrl-F7, I really doubt I did.
All this seemed to happen in the one account that I use daily, other accounts seems perfectly fine.
Is it possible that someone has been able to access my mac and change these settings?? I know this is not a huge problem to be worried about but I really am concerned.
The only changes I've made lately to OS X is install the latest security updates.
Please, someone give me an opinion and put my mind at ease!
Thanks
