Google Critical Security alert – a fake message which has nothing to do with the tech giant it “represents”

Google Critical Security alert
Google Critical Security alert is a scam which impersonates Google to collect users' credentials.

Google Critical Security alert is a fraudulent message which has been actively spreading around within the Gmail inbox. The email from no-reply@accounts or similar email address claims that someone just used your password to try to sign in to your account. Users are also advised to check the activity by clicking a button below the text. However, experts warn that Critical Security Alert from Google is set just to trick users into revealing their Gmail credentials to the cybercriminals or install malicious software on their device. Therefore, you should NEVER open the email or click on its content (especially if it is coming from a wgicg account). Nevertheless, Google uses a sophisticated technology to recognize and warn users about an illegitimate attempt of the login from a different device. For that reason, many warnings from Google are legitimate and should not be ignored. Those who use such services as VPN and Proxy[1] might encounter several Google security alert email messages due to a different IP login.
