Twitter users were notified by emails from the social messaging company saying that their passwords had been reset because Twitter “believes that your account may have been compromised by a website or service not associated with Twitter.” Despite the ominous-sounding warning, a spokesperson for Twitter says that the emails were sent out by mistake, CNET notes.
Twitter issued a statement apologizing to users inconvenienced by the error, noting that the emails were sent “due to a system error.”
The exact number of users who received the email and had their passwords reset was not disclosed by Twitter.
In January, Yahoo (YHOO) admitted that a third-party database had been compromised by hackers, who gained access to an unknown number of Yahoo Mail usernames and account passwords. Yahoo said that Yahoo Mail itself had not been breached by the hackers. Yahoo warned users affected by the incident to reset their passwords.
