SAN FRANCISCO —Yahoo has disclosed that the company was hacked for a second time, and this breach may have resulted in the theft of data associated with more than one-billion user accounts.
Yahoo reported that the new hack took place in August 2013, and is separate from a 500-million-account breach the company disclosed in September. As CUToday.info reported, when Yahoo reported its first breach three months ago, which possibly affected 500 million accounts, it was believed to be the largest on record.
Yahoo stated that it does not know who is behind the latest breach, adding that it does not appear the two incidents are connected.
“We believe that the August 2013 incident is likely distinct from the incident we disclosed on September 22, 2016," Yahoo said in a statement.
There is some overlap between the affected accounts, but Yahoo is not disclosing how much, USA Today reported.
