Once again another social medium has been breached and the passwords of millions are at risk of being sold in the dark web. This time, unfortunately, the medium is Twitter.

According to a blog post on Leaked Source, which has been known for its leaked database of login details, more than 32 million Twitter usernames and passwords are up for sale on the dark web.

Notably, this is the third major breach this year after 167 million passwords of LinkedIn were earlier stolen and released on the dark web, and a Myspace hack, which consisted of 360 million user accounts.

Meanwhile, Twitter has denied the breach of its system by hackers with company's security executive Michael Coates confirming that it was working with Leaked Sources to collect more information about the breach.

Moreover, spokesperson for Twitter mentioned that the system was not hacked. "We are confident that these usernames and credentials were not obtained by a Twitter data breach - our systems have not been breached," said the source, according to Tech Crunch.

"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," the source continued.

The evidence of Twitter credentials of millions of users were reportedly provided by a dark web user named "Tessa88@exploit.im".

Based on the information in the data, it is believed that the passwords were collected by malware infecting the commonly used browsers like Google Chrome and Firefox.

Twitter has recently posted in its support account mentioning that it is checking its data against recent password links.

Thus, data breach or not, if this has got users worried, it is better to stay safe and change the password immediately as a prevention measure, as it is always better to be safe than sorry.
