Twitter, an SNS giant company, announced a serious bug around user's password.
According to the official announcement, Twitter had erroneously stored some users' passwords unencrypted. Thus, they were at risk for getting stolen the password by a cracker. The bug has already been fixed.
As far as Twitter knows, there are no reports of bleaching so far. It does ensure no troubles will happen, however. Twitter is encouraging
users to change their password.
