"Switch to the Newest ATT-Yahoo Mail Inbox" email message below, which claims recipients' AT&T Mail classic version will be replaced by a new version, is a phishing scam being used to target AT&T customers. The phishing email message, which also claims that if the recipients do not update their information, their accounts will be permanently closed, is being sent by cybercriminals to trick AT&T customers into clicking on the link in it. The link in the email message goes to a fake AT&T website that will ask visitors to sign-in. Once visitors attempt to sign into the fake website with their AT&T credentials, the information will be sent to the cybercriminals behind the phishing scam.

Once the cybercriminals have received the stolen AT&T credentials, they will use it to hijack their potential victims’ accounts and use the accounts fraudulently. This is why AT&T customers should never click on links in email messages to sign into their accounts, they should instead, go directly to https://www.att.com/ and sign into their email accounts from there. If there is someone that needs to be done their accounts, they will be notified after signing in.
AT&T customers who have been tricked by the phishing scam are asked to contact AT&T for help.
