Google.com.co is a fake Google domain that was set up by a group of hackers to steal login credentials and other private user information from those who visited the site. The site mimicked the official Google login page to trick users into entering their usernames and passwords, which were then collected by the hackers for fraudulent purposes. Users are advised to only enter personal information on official Google sites ending in .com or .co.uk and to be wary of suspicious domains that mimic real companies.
