Yahoo is said to have secretly built a software program in 2015 to search all of its customers' incoming emails for U.S. intelligence, Reuters reported Tuesday. The company has challenged the report.
The company also confirmed in late September that over 500 million of its accounts had been breached in 2014 by a state-sponsored hacker. The company learned of the breach in July, according to a Washington Post report.
All of that is very bad news for a company set to be purchased by Verizon (VZ) for roughly $4.83 billion.
"If I were [Verizon], just from a business standpoint, I would probably reserve a bunch of money against the deal or go back to Yahoo and ask for a discount," former Yahoo interim CEO Ross Levinsohn said on CNBC's "Halftime Report" Wednesday. "Now if they do that, the question I have is: Does that open the process back up?"
Levinsohn served as CEO of Yahoo from May 2012 to July 2012 before Marissa Mayer took his place.
"I think it's troubling," Levinsohn said of the data breach. "It certainly was not something that was disclosed to my knowledge, the hack. It's likely something that the company knew about."
Shares of Yahoo were slightly higher in Wednesday afternoon trading.
