The LeakedSource website adds that hacked Twitter data is comprised of 32,888,300 records, including not only email addresses but also usernames and passwords.
Most of the passwords are said to be in plain text.
While the details on how the hack was implemented are not yet known, LeakedSource says that the hacker might have collected data using malware affecting popular browsers like Firefox and Chrome, or might even have picked up details directly from Twitter.
On the other hand, Twitter says that their systems have not been breached, "We are confident that these usernames and credentials were not obtained by a Twitter data breach - our systems have not been breached. In fact, we've been working to help keep accounts protected by checking our data against what's been shared from recent other password leaks," said a Twitter spokesperson.
Twitter is only one of the many victims that have been hacked recently like MySpace, LinkedIn and even Mark Zuckerberg.
