Yahoo fell 6% in yesterday’s trading on word that Verizon is now considering scrapping its $4.83B deal for the Internet pioneer. Yahoo (NASDAQ:YHOO) on Wednesday disclosed a security breach that it believes compromised information on more than a billion user accounts, which is is thought to be separate from a previously disclosed incursion affecting half a billion accounts, and reports that Yahoo scanned thousands of customers’ e-mails on behalf of government intelligence services. Verizon (NYSE:VZ) may yet seek a price cut; after fall reports of the first reported hack, parties at Verizon indicated the deal still made sense.
