A teenager trying to display a unicode heart, found a major fault within Tweetdeck.
The unicode would be display the whole tweet as HTML code allowing users to do some fun things.
Change the formatting of tweets, or put an alert on users' screens.
Within 90 mins somebody had worked out a way to make users who see a certain tweet retweet that tweet spreading like a worm.
As of right now the tweet has 80K retweets.
Worm used XSS to do the retweet, the worry was accounts could be taken over if more XSS exploits was created.
It appears that worry was more just retweets over anybody taking your account.
Anywho, if you're curious what happened to tweetdeck that's why. Twitter has fixed the issue, but due to the wonderful world of cache the patch is slowly going live.
