All 3 billion accounts were hacked in the 2013 data theft making it the largest breach in history.
Yahoo disclosed the actual number of accounts hacked in a disclosure tripling the size of the breach from the 1 billion it mentioned last year.
Yahoo on Tuesday said the company had “recently obtained new intelligence” showed all user accounts had been affected.
While Yahoo say that stolen information did not include passwords in clear text, payment or card data or bank information, I think I speak for all Yahoo account owners when I say… whatever.
Verizon in February lowered its original offer by $350 million for Yahoo assets in the wake of two massive cyber attacks at the internet company eventually buying the company for $4.8 billion.
This news will likely be a bombshell for the company who will now have to face the lawsuits brought by Yahoo’s users.
The new revelation follows months of scrutiny by Yahoo, Verizon, cybersecurity firms and law enforcement that failed to identify the full scope of the 2013 hack.
The investigation underscores how difficult it was for companies to get ahead of hackers, even when they know their networks had been compromised.
Chairman of the U.S. Senate Commerce Committee said on Tuesday he plans to hold a hearing later this month over massive data breaches at Yahoo and Equifax Inc.
Senator John Thune said he will ask witnesses from the two firms whether “new information has revealed steps they should have taken earlier, and whether there is potentially more bad news to come.”
