The email message below, which claims the recipients have exceeded their mailbox storage limit is a phishing scam being used to target AT&T customers and Yahoo users. The phishing email message is being sent by cyber criminals to trick AT&T customers and Yahoo users into clicking on the link in it. The link in the email message goes to a fake AT&T or Yahoo website that will ask visitors to sign-in. Once visitors attempt to sign into the fake website with their AT&T or Yahoo usernames and passwords, the information will be sent to the cybercriminals behind the phishing scam.

Once the cybercriminals have received the stolen AT&T or Yahoo usernames and passwords, they will use it to hijack their potential victims’ accounts and use the accounts fraudulently. This is why AT&T and Yahoo user should never click on links in email messages to sign into their accounts, they should instead, go directly to https://www.att.com/ or https://mail.yahoo.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. While Yahoo users are asked to change their passwords. For Yahoo users whose accounts have already been hijacked, are asked to go to https://mail.yahoo.com and click the "Trouble signing in?" link for help regaining access to their accounts.
