If you've ever created an account for the url shortening service Bitly before, you'll want to listen up. Bitly has now announced via their blog that they have reason to believe that Bitly account credentials have been compromised and are suggesting users change their API keys and OAuth tokens.
We have reason to believe that Bitly account credentials have been compromised. We have no indication at this time that any accounts have been accessed without permission.
