Yahoo has issued a new warning to account holders about malicious hacks linked to a third data breach that the company disclosed late last year.

The warning relates to more recent malicious activity targeting accounts between 2015 and 2016, most likely perpetrated by a "state actor", according to Yahoo. Specifically, the hacks are said to have been achieved by using "forged" cookies - the text-based keys that give web users access to username and password information without having to re-enter it - created by software stolen from within Yahoo's internal systems.

A message was sent to affected Yahoo users on Wednesday, warning them of the unauthorized access to their account, but Yahoo did not reveal how many people were notified.

Yahoo's announcement came just hours after reports that Verizon was close to a renegotiated deal to buy Yahoo's core assets at a lower price. Last year, Verizon agreed to buy Yahoo's core business for $4.83 billion, but on Wednesday Bloomberg reported that the renegotiated deal would slash about $250 million off that price because of the security breaches that were revealed after the initial deal was agreed. 
"As we have previously disclosed, our outside forensic experts have been investigating the creation of forged cookies that could have enabled an intruder to access our users' accounts without a password," a Yahoo spokesperson told Associated Press. "The investigation has identified user accounts for which we believe forged cookies were taken or used. Yahoo is in the process of notifying all potentially affected account holders. Yahoo has invalidated the forged cookies so they cannot be used again."
Back in September, Yahoo revealed that hackers had stolen the personal data of "at least" 500 million users, but by December, the internet company admitted that over one billion Yahoo user accounts had been compromised in a separate hack dating back to August 2013. Information stolen included names, email addresses, phone numbers, birth dates, hashed passwords, security questions and answers.

The internet company is currently under investigation from the Securities and Exchange Commission over its failure to disclose its massive data breaches sooner.

Forged cookies?! Geez, that's about as bad as it gets.
We don't need Yahoo anymore. They just need to die along with Adobe Flash.
One exception: Yahoo! Finance is still useful because Google Finance kinda sucks. And speaking of Flash, Google uses it for interactive charts for some reason.
Seriously? Forged cookies? What is this, 1998?
No. This. Is. Yahoo!!!!

Verizon would be foolish to close this deal, revised or not. There's no many problems with Yahoo now, and clearly the hacking problems are material enough for them to walk away. I never got why Verizon wanted to buy them in the first place.

A 250 million dollar discount still isn't enough. It's been clear for a long time that yahoo has been a lax company floundering around rudderless with no direction which have allowed these problems to happen. Whoever buys this company is inheriting a mess. Not really sure why Verizon even wants them.

Turns out, the "state actor" was just a stand-in for Romeo in a local theater production trying to figure out how to disable ads in his inbox.

I just hate people like Marissa Mayer who seem so excited to change the world and once they fail they hide away... she is hardly tweeting. False promises.

That being said, what is it that Verizon willing to pay Yahoo $4.8B for? Also, Market Cap of Yahoo is $43B , is it just made of the Ali Baba shares?

A great philosopher once sang:

"If moon was cookie me think me would be
Happiest monster you ever see

Me put on a space suit then up through the night
Me ride in a rocket to go take a bite

Me take bite from here
Me take bite from there
And pretty soon, me bite everywhere

Me eat with both hands
No need fork or spoon
Me chew it all up until there no moon

If moon was cookie it wouldn't be fine
Because if me ate it then it wouldn't shine

Me come to the window and look up at night
But no little moonbeams would give me their light

So me not like to say it, but it clear to me
It lucky the moon is not a cookie."

Why even password protect my yahoo account anymore? It seems like everyone else can access my stuff except me.
I cancelled and deleted my yahoo account.

I never really used them for emails so I'm happy about that, but the last hacking (prior to this) caused to me act. I recommend moving off of them

For what it's worth, my AOL email from 1999 is still going strong. :)

I think yahoo needs to go away after this latest breach.
