Twitter locks some accounts after passwords exposed

The measure follows the leak of nearly 33 million purported usernames and passwords

Twitter said it had locked down and called for a password reset of some accounts after an unconfirmed claim of a leak of nearly 33 million usernames and passwords to the social network.

The company said the information was not obtained from a hack of its servers, and speculated that the information may have been gathered from other recent breaches, malware on victim machines that are stealing passwords for all sites, or a combination of both.

“In each of the recent password disclosures, we cross-checked the data with our records. As a result, a number of Twitter accounts were identified for extra protection. Accounts with direct password exposure were locked and require a password reset by the account owner,” Twitter’s Trust & Information Security Officer, Michael Coates said in a blog post on Friday.

Millions of users have been notified by Twitter that their accounts are at risk of being taken over, reported the Wall Street Journal on Thursday.  The company did not specify to the newspaper how many users were notified and forced to change their passwords but said that the total is in the millions.

Hacked information database LeakedSource revealed on Wednesday that it had acquired a database of 32.8 million records containing Twitter usernames, emails and passwords from a user who goes by the alias Tessa88@exploit.im., but there were questions from some experts as to the authenticity of the data.

The same user provided LeakedSource with names and passwords of alleged users of MySpace.com and VK.com.

“We have very strong evidence that Twitter was not hacked, rather the consumer was,” LeakedSource said. It pointed out that the passwords were in plain text with no encryption or hashing. Twitter said it used a password hashing function called bcrypt. The credentials are “real and valid” as out of 15 users asked, all 15 verified their passwords, LeakedSource said.

Windows 10 for Business / Dell XPS

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Windows 10 / HP Spectre

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
