Verizon, the new parent company of Yahoo, announced Tuesday that the breach for its subsidiary originally estimated to affect 1 billion users was likely a couple billion shy.

The 3 billion figure comes as new information was analyzed in recent months, according to The Wall Street Journal. Yahoo announced in December that one billion user accounts were hacked two years ago, an incident separate from another cyber intrusion where roughly 500 million accounts were breached. Both of the cases are likely the two largest single cyber thefts ever, even before the latest update. (RELATED: Judge Says Yahoo Must Face Lawsuit After Data Breach Exposed Hundreds Of Millions)

At first, Verizon cooled on the Yahoo purchase after the second breach was disclosed, but eventually purchased the company, specifically its internet business, for $4.5 billion. The original deal was worth $4.83 billion, but was cut by around $350 million, due to the respective breaches.

Yahoo, and through its purchase Verizon, aren’t the only companies to deal with a massive virtual infiltration, and then subsequently raise its projections for affected customers.

Equifax announced Monday that at least 2 million more customers may have been affected by a security breach, raising an original rough estimate of 143 million people to approximately 145.5 million.
