Wi-Fi technology has boomed tremendously over the past 2-3 years. It's convenient at home, very convenient in public places to grab your email or spend hostage time, convenient in the office if you have to go to conference rooms all the time. I've been tracking this space for quite some time: check my Wireless category for this blog, and also my new Wireless category in my blog roll (bottom left).
Doing it all the time ? Think again! A recent SecurityFocus report warns you again about the tools available out there for wireless communication interception (airsnort, weplab, aircrack, etc.).
I remember sitting in a VC conference about a year ago with Hervé Schauer in the room. A lady was trying to persuade me to use their new WLAN connectivity at the conference: I said no way if Hervé is in the room! I've known him for about 10 years, and it's not that I wouldn't trust him: it's just that I am sure he can crack into my PC, and intercept my emails in a matter of minutes: his firm does a lot of security consulting (I really recommend using them) and develops tools that are available for the general public...
Hence, I read today that Joi is going to the Chaos Computer Club conference... waow! way to go! He points to one of their posts on how to secure your box while at the conference (great humor: it's called 'How to Survive'...). My advice would be to leave the computer at home... There is no such thing as 100% security, and tempting the folks at a CCC reunion is probably a bit too much ;)
I talked a bit about the hacker culture and some books I recommend about it here.
