Well sorry to say but it’s kind of serious. Probably the biggest security threat to happen in our (and the internet’s lifetime).
If you use any of the services kindly published by Mashable please (please please!) change your password. I know it’s annoying but it’s definitely necessary.
So again, if you’re using any of these sites (or you have in the past and use the same password everywhere), update all of them over a winesky tonight. Just remember to write the new passwords down somewhere so you remember it in the morning!
