Yahoo is poised to confirm a massive data breach of its service, according to several sources close to the situation, hacking that has exposed several hundred million user accounts.
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 one 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 has possible larger implications for 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 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.
