The website is being operated by cyber criminals who trick their potential victims into visiting it by disguising it as their online account website. Once on the phishing website, potential victims or visitors will be asked to sign into their online accounts. But, any attempts to sign-in will result in the visitors' online account credentials being sent to the cybercriminals.
