Google warns Gmail users when believing that they are targeted by hackers who are employed by governments. These users get a bar at the top image in which a warning is displayed.
According to Google, a notice will appear at the top of the Gmail page that says “Warning: We believe state-sponsored attackers may be attempting to compromise your account or computer”. But the Internet giant thinks there are hackers who try to take over the account. According to Google, users who receive the warning bar on screen steps to secure their Gmail account, for example by a different password to set or by Google’s own two-step authentication on.
The bar is designed to warn of hackers who are paid by governments, says Google. The company does not want clarity about how the user determines whether a government target of hackers because its detection would not relinquish. In July 2011, Google also warned customers whose systems were infected with fake antivirus software, or “scareware.” In that instance, Google became suspicious when it uncovered “unusual search traffic” while doing maintenance at one of its data centers.
