Twitter Mouseover Security Flaw Affecting Thousands of Users [WARNING]
I got hit when I mouse-over-ed some text. It automatically re-tweeted someone's tweet (which, presumably, was 'infected' too), and opened up a pop-up window to another site off-Twitter.
When I first read a couple of tweets cautioning against it, I didn't believe it could happen by just hovering over the link with my mouse (only if I clicked)... but nope! It hits even with a mouse-over.
TweetDeck is safe. For now
Just a quick heads-up!
edit: The situation is reported to be resolved:
