Remember Firesheep, the Firefox add-on that can sniff out credentials for Facebook and Twitter on public Wi-Fi? A new Firefox add-on called Idiocy performs the hacking automatically in an attempt to educate victims about the security vulnerability.

"I browsed twitter insecurely on a public network and all I got was this lousy tweet. http://jonty.co.uk/idiocy-what"
That's what you'll see in your Twitter feed if you get auto-hacked by Idiocy. This add-on falls under two categories: hacking for the greater good and illegal. Actually using Firesheep is considered illegal in most parts of the world, since you're breaking into someone's account, so we can't recommend it in practice. Instead, you can help protect yourself and others with another add-on called FireShepard. FireShepard works by attempting to crash Firesheep with a bunch of nonsense packets. Alternatively, you can just make a habit of visiting your social sites securely (https, not http) instead.
