I am very paranoid over what comes in and out of my computers. I’ve got scripts that monitor incoming packets, I pour through logs to see what’s going on in the network at home, I try to make sure that what there’s no malicious things starting from or ending up in my system.

I’m an avid bluetooth fan, for its ease of use and implementation in a lot of devices that I find cool. I’ve had confidence that my machine was safe at work, until this afternoon. I got back from a meeting and I noticed a small window saying that I had a received a picture from a Nokia mobile phone. I clicked on the magnifying glass to see where the image was downloaded and the picture below popped up. My computer was set up to automatically receive files from stray bluetooth devices. Pissed off, I poured through the ‘Bluetooth’ preference panel in ‘System Preferences’. Under the sharing properties of ‘Bluetooth File Exchange’, I opted for the rule “Refuse all”
