URL shortening service Bitly has issued an urgent security warning saying that its users’ account credentials may have been compromised. Bitly shortens more than one billion links per month and powers over 10,000 custom short URLs and offers an enterprise analytics platform that helps web publishers and brands grow their social media traffic. The company has disconnected the Facebook and Twitter accounts of all users and is requesting users to change their passwords and reset their API keys and OAuth tokens. The service originally served as the default link shortener for Twitter, until Twitter developed its own product service in 2009.
