Just over 24 hours ago we reported that Twitter was experiencing a global outage, but more information has been released by Twitter where they've announced that they were actually victims of some attacks this week.
Twitter took to their company blog where they said during the week they had detected "unusual access patterns" that led them to see that unauthorized attempts to access users' data was made. Twitter actually discovered one attack as it was happening, where they were able to quickly shut it down shortly after.
The social networking site said that the attackers may have had access to information for close to 250,000 different users. Twitter added "usernames, email addresses, session tokens and encrypted/salted versions of passwords" would have been available.
Twitter have since reset the passwords and revoked session token for all affected accounts, with affected users to expect an email notifying them of the reset. Because of the hack, Twitter have taken the time to "echo" the recent advisory by the Department of Homeland Security, who have told users to disable Java on their systems for the best security.
