Yahoo users, be aware of email messages like the one below, which claim that your accounts activation expires and you need to upgrade to avoid email termination.

The link in the phishing email message goes to a fake or phishing Yahoo website, which will attempt to trick the potential victims into entering their usernames and passwords on it. If Yahoo users attempt to sign into the phishing website with their Yahoo usernames and passwords, it will be sent to the cybercriminals behind the email scam, who will use the information to hijack their accounts. The hijacked Yahoo accounts will then be used by cybercriminals fraudulently.
Remember, if you receive email messages like these, please go directly to your email account instead of clicking on the links in the email messages. If there is something wrong with your account, it will be shown to you after signing in. And, if you were tricked by one of these phishing scams, please change your password immediately before your Yahoo account is hijacked.
