Yahoo users should never click on a link to sign into their accounts; they should instead, go directly to mail.yahoo.com or yahoo.com and sign-in from there. Once they are signed in, they will be alerted to updates, changes or other important notifications. Going directly to Yahoo’s website to sign into their accounts, will protect Yahoo users from phishing links that go to fake websites that steal usernames and passwords. Phishing websites steal their visitors’ usernames and passwords by asking them to sign into their accounts on the same fake website. Once visitors to the websites attempt to sign-in, their usernames and passwords (credentials) will be sent to the cybercriminals responsible for the phishing websites. As soon as the cybercriminals receive their potential victims’ usernames and passwords, they will sign into their accounts, hijack and use them fraudulently.

Yahoo users who have been tricked by the fake upgrade email, are asked to change their Yahoo passwords immediately before their accounts are hijacked and used fraudulently.
