The Largest Hack Ever? Yahoo Admits 2013 Data Breach Impacted All 3 Billion Accounts

Is it too late for Verizon to get some more of its money back?

After the entity responsible for selling Yahoo agreed to cut $350 million off the company’s sales price earlier this year following revelations that hackers had stolen sensitive  account information of as many as 1.5 billion user accounts during two separate data breaches, the Wall Street Journal is now reporting that the scale of one of those intrusions was much larger than initially believed.

A 2013 data breach that was initially believed to have impacted 1 billion, actually impacted all of Yahoo's 3 billion user accounts, Verizon announced on Tuesday. Verizon’s acquisition of Yahoo formally closed in June after contentious negotiations that were complicated by the discovery of the hacks. The smaller of the two incidents, which took place in 2014, was first disclosed to the public last September. It reportedly involved 500 million user accounts. Three months later, in December, the company publicized the 2013 hack.

The stolen data included names, email addresses, dates of birth, telephone numbers and encrypted passwords, Yahoo has said. In October, before the second breach was even disclosed, Verizon signaled that it would likely consider the data breach to be a “material event”, allowing it to change the terms of its deal to buy Yahoo, which it did in February.

As WSJ pointed out, the disclosure shows that executives are still coming to grips with Yahoo's myriad security problems.

Even before the number of affected user accounts was revised higher to 3 billion, the breach was still the largest on record by number affected. However, most experts consider the Equifax breach, which involved sensitive financial and personal information like credit card, social security and drivers’ license numbers, more damaging than the Yahoo breach.

A spokesman for Oath, the new name of Verizon’s Yahoo unit, said the company determined last week that the break-in was much worse than thought, after it received new information from outside the company. He declined to elaborate on the source of that information. Compromised customer information included usernames, passwords, and in some cases telephone numbers and dates of birth, the spokesman said.

Fortunately for Yahoo executives, as part of the revised deal, Verizon agreed to forfeit the right to sue Yahoo for allegedly covering up the hacks. Meanwhile, the entity selling Yahoo has retained liability for an SEC investigation that was launched in January, as well as any shareholder lawsuits related to the deal itself.

 Just who has enough storage for such a hack?

AurorusBorealus's picture

There is plenty of storage space in Utah, but I am sure that the Russians did it... probably as part of their plan to influence the U.S. election.

Owners of said facility in Utah wouldn't need to hack infornation they already have.

i hope we can give all our medical information to a government run health care system cuz that security would be so expertly done, and well managed, that no one could ever ever hack it. /s

Anyone that wants it. 3 Billion accounts. 3 TB drives for $100 - $200. 1KB per account. Way more than needed for each account. This problem is going to keep happening unless computer security gets a complete reset.

VWAndy's picture

Depends on how much they got on each person.

Class-action lawsuit.  Put all of these internet data-gathering companies out of business.  That is the only solution, since national governments and regulators are unable and unwilling to restrain the power of these internet panopticon companies.

 I think ebay has been breached, and is hiding it.

 Additionally, I think all three of the major CRA's have been breached. 

 A little birdie at LexisNexis told me.

 I didn't ask about that. You're probably correct.

How come I haven't read this on Yahoo News???  All they have are "Trump -is-an-Idiot" stories.  Not "We Screwed Up!" stories.

Big deal, health insurance companies openly leak health related information of patients to drug companies. How else do you think Martin Shkreli figured out he could raise the price of Thiola 10 times? This price hike stands even today, while Shkreli is in jail. (, even today its the most expensive drug in its class.

By definition, we don't KNOW what the biggest hack truly is...but I bet it's greater than anyone can ever imagine.

 All of it is my guess. Every last digital pixel.

Guaranteed it's a politican or a "journalist".

Isn't that obvious? It's Putin. It's always Putin's Russia.

He also brainwashed the guy in Vegas and made the sound booms in Havanna. When your milk turns sour, that is also Putin's fault.

Why hasn't Mueller even released a photo of a Russian cocktail napkin?  We already have photos of a mass shooters room, weapons and someone's head suicided (I think it is one from Hillary's file. Like a cop who walked in on Bill and an intern and has to be off'ed).

she run out with the cash like a bandit, talking about someone being on the right time and the right place, from being in charge of designing the Google query interface, yes that interface that is a search box under the Google logo to CEO of a multibilion company for being a woman and being able to walk and chew gum

"The entity selling Yahoo" Is it a big secret? Your sources wouldn't let you name it? Or would China block your site if you named it?

Does it matter?  Who has time to filter 3 billion accounts?

That's it, I'm changing my birth date.

And I'll charge all the fees to Oaf.  Who would name a division Oaf?  Even if it's true.

The Yahoo enterprise is an embarrassment to... Everyone.

A Big Huge poster child for much of what ails us.

Piss on Yahoo and shit on Verizon.


Coporations whose CEO's sport tits deserve what they have coming.

Yahoo is a shit website filled with liberal propaganda. Everything from gender bending nonsense, Trump bashing, anti-masculine articles and other faggotry. And I gurantee any day of the week you go to their homepage and scroll down the news you will find something "Kardashian" related. Couldn't take it anymore, that's how I ended up here.

I Write Code's picture

They were "hot" circa 2001.  But then they were blitzed in search by Google.  Then they forgot how to code and kept breaking their own sites.  They they forgot why to code and started the same "sponsored content" ads that look like news shit that Tyler just put here on ZH.  And then they were gone.

GodSpeed_00's picture

Yeah I remember all those "sponsored" articles. Honestly I used to like Yahoo a long time ago. It's the first website I visited on the Web in the 90's and the first one that I used messenger/chat.

3 billion accounts, yeah right.  that sounds suspiciously like facebook math.  anyone who would give yahoo any information about themselves obviously isn't too worried.

I think all this security business could be fixed if more companies would hire women and negroes to sort out all this tech stuff.  With Marissa gone, are Lex "It's Unix...I know this..." Murphy and Morgan Freeman available to be CEO and CIO?

Who the fuck has a Yahoo account. I closed mine 20 years ago. Well the truth is you can't really close it, you have to just sort of abandon it, hence their 3 billion math number.

yellowsub's picture

I think most of those billions are used for spamming.

Was Yahoo spending all of their money on storage?
