The fake "AT&T Yahoo! 2019 Agreement Update" email below is a scam. Therefore, recipients are asked not to click the link in it. The link in the fake email goes to a phishing website that looks exactly like AT&T's website. Visitors to the website will be asked to sign-in, but any attempts to sign-in will result in their account credentials be sent to the cybercriminals behind the phishing scam.
Once the cybercriminals have stolen their potential victims' account credentials, they will use it to gain access to their accounts, and use the accounts maliciously.
