Yahoo! reports yet another data breach Featured


Yahoo! says that it may have been affected by a data breach that occurred between 2015 and 2016, but has not offered any indication of the number of users who may be affected.

The company made two disclosures last year — one in September and one in December — of massive data breaches.

The leak disclosed in September involved about 500 million user credentials and took place in late 2014. The December disclosure concerned account details of a billion users and occurred in August 2013.

On Wednesday US time, the company said in a statement that the breach had come to light during an investigation into the billion-account breach it had announced in December.

It laid the blame on what it described as a "state-sponsored actor", the same party it blamed for the other two breaches.

The two breaches reported last year have caused a delay in the finalisation of the sale of some of Yahoo!'s assets to Verizon.

A message sent to Yahoo! users on Wednesday read: "Based on the ongoing investigation, we believe a forged cookie may have been used in 2015 or 2016 to access your account."
