Twitter has warned its 330 million users to change their passwords as a result of a bug that caused passwords to be logged in plaintext before being hashed. The social network does not appear to have been misused by cyber criminals nor have Twitters systems been breached or misused to access these plaintext passwords. Twitter is the second company this week to reveal the existence of a bug in its password management systems, with GitHub announcing a similar vulnerability just days ago. Twitter also emphasizes that the vulnerability has been addressed, while apologizing for the incident.”]
