I am a past ATT customer and Experian Identityworks found my name, address, phone number, att email address and social security number on the dark web. On Joy. They surmised it was from the ATT Data breach. If you are a current or past ATT customer you may at risk as well. ATT has stated it effects 70 million past and present customers. I established a credit freeze with all 3 credit bureaus and hope for the best.
