Twitter has been hacked. If you have a Twitter account (and who doesn't these days), it's probably a good idea to make sure everything is in order and/or reset your password with something strong. Twitter says that approximately 250,000 users may have been affected by the hack, with the hackers gaining access to usernames, email addresses, session tokens and encrypted version of passwords. Not good.
Twitter discovered "unusual access patterns" this past week that led it to identify unauthorized access attempts to Twitter accounts. They shut one live attack down but discovered that around 250,000 users may have been compromised. Twitter says:
As a precautionary security measure, we have reset passwords and revoked session tokens for these accounts. If your account was one of them, you will have recently received (or will shortly) an email from us at the address associated with your Twitter account notifying you that you will need to create a new password. Your old password will not work when you try to log in to Twitter.
A lot of hacking going on lately, it's probably a good idea to audit your accounts to make sure nothing is borked. [Twitter]
