Looks as though a third party app was hit for a phishing scam that has allowed the perps to appear to take over hundreds of Twitter accounts. According to Mashable, since all of the spammed tweets mention coming from the API, the accounts themselves are probably still OK. It’s the app they’ve allowed access to that’s been compromised.

TIP: Always think twice before giving an app access to your account. Do your friends use it? Have they had problems? When in doubt, Google the app. See if it’s legitimate before you click allow.
