Yahoo has confirmed today that the data breach they suffered in 2013 had a wider scope than previously imagined – affecting all three billion of its users, as opposed to the previously estimated one billion who were thought to be affected.

The data breach, which was discovered in December last year, was initially thought to only have covered a limited scope of Yahoo's userbase; however, Oath, Verizon's parent digital media company, has disclosed that is more than likely that Yahoo's entire userbase at the time of breach was affected by this enormous cybersecurity lapse. The breach exposed a variety of user details; everything from names and email addresses to hashed passwords, phone numbers and user birthdays- however it is important to note that no financial information was breached.

According to a statement released by Verizon:

"The company recently obtained new intelligence and now believes, following an investigation with the assistance of outside forensic experts, that all Yahoo user accounts were affected by the August 2013 theft,"

Verizon, in due diligence regarding the purchase of Yahoo, is continuing to investigate the deeper details of the data breach and the effects it has had and will have on the end-user.

A statement from Chandra McMahon, chief information security officer at Verizon, read:

"Verizon is committed to the highest standards of accountability and transparency, and we proactively work to ensure the safety and security of our users and networks in an evolving landscape of online threats," "Our investment in Yahoo is allowing that team to continue to take significant steps to enhance their security, as well as benefit from Verizon's experience and resources."

While Yahoo have made a commitment to trying to make amends by investigating the breach and improving security of this services, there is no doubt that this will shatter consumer confidence in the company. Regardless of what services you use, we always advise that you undertake good security practices such as never reusing passwords and always using two-factor authentication.

Furthermore, if you are a Yahoo user we would strongly advise doing what our friend's at iMore did – delete your account and just use Outlook or Gmail like a normal person. Seriously. When was the last time anyone used Yahoo?

What do you guys think? Were you a former Yahoo user who got hacked? How will this shape the future of cybersecurity? Let us know in the comments or post over in the forums with your thoughts.
