It was revealed Wednesday that over 1 billion Yahoo accounts have been hacked, which is not good news for a company that had 500 million accounts hacked in 2014 and in the midst of negotiating a $4.8 billion sale to Verizon. Verizon Communications learned of Yahoo's data breach in the past few weeks, according to Dow Jones. The company has all options on the table regarding its deal to acquire the company, including renegotiating the price or walking away, but it wants to see the impact on Yahoo's users and its business. Yahoo’s shares fell 2.4% in after-hours trading, while shares in Verizon ticked up.
