    To me, showing people how to hack into wifi networks (and other “evil” how-to’s) by Lifehacker is just plain irresponsible and can easily encourage otherwise law abiding readers to carry out these hacks. Just show how to stop the illegal activity, now how to do them. “Evil week” just encourages people to be evil. Why not change this to “Beat the evil” week and help people protect themselves? You can mention the ways your privacy can be hacked, but don’t go into detail and don’t provide links to evil software. Who’s side are you really on?

      Here’s the thing: The information is already out there, regardless of whether or not Lifehacker spreads it or not. Pandora’s box has been opened. You can’t make people “un-know” this information, and the people that were doing this before will do it again. Putting the information here is an informative process, and is actually an advocacy move to get the router companies to update their flailing technology, as well as to let consumers know that just because you have a password up does not mean you are secure.

      The idea is that if you take something that is underground, like knowing how to crack a safe, pick a lock, or crack a wifi password, and put it into the public eye, people will fix the security issues quicker. It works. There’s a reason that you can’t break into someone’s house with a “skeleton key” anymore, or why you can’t break into a good safe with a drill. If it stays secret, then the people that use it for evil will keep using it, and the amount of people affected by it will be greater in the long run than if the secret had been blown wide open and people went hog wild for a few months.

      Security is an arms race, and the only way to win is to stay knowledgeable.
