'Update: 09/22 18:47 GMT by M :Yahoo has confirmed the data breach,
adding that about 500 million users are impacted. Yahoo said "a copy
of certain user account information was stolen from the company's
network in late 2014 by what it believes is a state-sponsored actor."
As Business Insider reports, this could be the largest data breach of
all time. In a blog post, the company said:
Yahoo is notifying potentially affected users and has taken steps to
secure their accounts. These steps include invalidating unencrypted
security questions and answers so that they cannot be used to access
an account and asking potentially affected users to change their
passwords. Yahoo is also recommending that users who haven't changed
their passwords since 2014 do so.
The Intercept reporter Sam Biddle commented, "It took Yahoo two years
to announce that info on half a billion user accounts was stolen."
Amid its talks with Verizon for a possible acquisition -- which did
happen -- Yahoo knew about the attack, but didn't inform Verizon about
it, Business Insider reports. Original story, from earlier today,
Last month, it was reported that a hacker was selling account details
of at least 200 million Yahoo users. The company's service had
apparently been hacked, putting several hundred million users accounts
at risk. Since then Yahoo has remained tight-lipped on the matter, but
that could change very soon. Kara Swisher of Recode is reporting that
Yahoo is poised to confirm that massive data breach of its service.
From the report:
While sources were unspecific about the extent of the incursion, since
there is the likelihood of government investigations and legal action
related to the breach, they noted that it is widespread and serious.
Earlier this summer, Yahoo said it was investigating a data breach in
which hackers claimed to have access to 200 million user accounts and
was selling them online. "It's as bad as that," said one source.
"Worse, really." The announcement, which is expected to come this
week, also possible larger implications on the $4.8 billion sale of
Yahoo's core business -- which is at the core of this hack -- to
Verizon. The scale of the liability could be large and bring untold
headaches to the new owners. Shareholders are likely to worry that it
could lead to an adjustment in the price of the transaction.'
