Microsoft Outlook users who have the received the "Outlook Upgrade Now to the Newest Version" email below, which claims that they need to upgrade to a new version to avoid deactivation, are asked to delete it. The email is a fake and is being sent by cybercriminals to bait potential victims into clicking on the link in it. The link goes to a fake Microsoft Outlook website that steals email account credentials if visitors attempt to sign-in.
Once cybercriminals have gotten their potential victims’ account credentials (usernames and passwords), they will use it to hijack their Microsoft accounts and use them fraudulently. Therefore, recipients of the phishing email message (see below) who were tricked into clicking on the link within it and have attempted to sign into the phishing or fake website that they were taken, are asked to change their Microsoft account passwords immediately, before they are hijacked and used fraudulently by cybercriminals.
