Names, email addresses and passwords, but without financial information, are hurt, said Yahoo last year.
New discoveries took place 4 months after Verizon (VZ, Tech30) acquired Yahoo’s $ 4.48 billion ownership. Yahoo is an oath, part of the digital media company Verizon.

“The company recently has a new intelligence and now believes after an investigation with the help of external forensic experts who are all Yahoo account users affected by a flight from August 2013,” Verizon said in a statement.
Verizon would not provide any information about external legal experts. Yahoo sends emails to other affected accounts. After hacking the discovery last year, Yahoo has asked for a password change and an unsecured security issue to protect the user’s information.
