Phishing in Your Inbox: How to Reliably Identify Fake Emails in Your Google Account

(This text was translated from English into German with the help of AI.) Cybercriminals are using increasingly sophisticated methods to obtain your login credentials. A phishing email that looks deceptively like a genuine message from Google can quickly become a serious security risk. But how can you distinguish a legitimate security alert from an attempted scam? As cybersecurity experts, we provide you with the knowledge you need. We explain how phishing works with Gmail, how to recognize a fake email, and what protective measures you can take to minimize the risk to you and your company. What is a Gmail phishing attack? A Gmail phishing attack is an attempt by attackers to trick you into revealing your Google login credentials, namely your email address and password. The most common method is to send an email that claims to come from Google itself. This phishing email usually contains a link to a fake sign-in page. This page is often an exact copy of the genuine Google login page. If you enter your details there, they are sent directly to the attackers. With this information, cybercriminals can not only read your emails, but also change your password to lock you out and access all services linked to the account. The Anatomy of a Google Phishing Email: Typical Warning Signs Although phishing emails are becoming increasingly professional, there are still signs that can help users recognize an attempted scam. The Fake Sender Check the sender address carefully. Cybercriminals often use addresses that look very similar to the official email address but contain small deviations (e.g. “google.support.com” instead of “support.google.com” or misspellings such as “gogle.com”). Do not be misled by the displayed name. What matters is the actual email address, which is often only visible when you hover over the name. Move the mouse pointer over the sender without clicking. Urgency and Threats Phishing text messages, phishing calls, and phishing emails almost always create psychological pressure. Typical wording includes: “Your account has been temporarily suspended.”, “Suspicious activity detected. Confirm your identity.”, or “Your storage is full. Click here to upgrade.” Such messages are designed to provoke a quick, ill-considered reaction. A genuine Google security alert will never pressure you to click a link immediately and enter your password. Impersonal Greetings and Suspicious Links An impersonal greeting such as “Dear user” is a clear warning sign. As with the sender, hover over a link without clicking it to see the actual destination URL. If the link leads to an unknown or suspicious-looking domain, it is very likely to be a phishing attempt. How can I tell whether a Google sign-in page is fake? If you have clicked a link and arrived at a sign-in page, inspect it carefully before entering any data: - Check the URL in the address bar: Google’s genuine sign-in page is always hosted on a domain such as accounts.google.com. Look for small deviations in the address, such as hyphens or additional words. - Look for the padlock icon at the beginning of the address bar: A secure connection is indicated by a padlock icon in the address bar. If it is missing or the browser warns you about an insecure connection, exercise extreme caution. However, relying on the padlock alone is not sufficient. A basic website certificate can be obtained free of charge or for a small fee. - Completely unencrypted websites do still exist, but they are relatively rare. Depending on the browser, you will usually see a prominent warning and have to click through it before reaching the page. In other words, you are unlikely to land on such a page “by accident.” - Test the page: Deliberately enter an incorrect password. A fake page will often accept it and simply redirect you, whereas the genuine Google page will display an error message. Emergency Plan: What to Do After a Successful Phishing Attack If you suspect that you have fallen victim to a phishing attack, acting quickly and systematically is essential to limit the damage. The exact steps depend on whether you entered login credentials or are facing an unauthorized demand. If you suspect compromised login credentials: If you entered your password on a fake page, you must assume that your account is at immediate risk. Take the following steps straight away: - Change your password immediately: Go to the official Google Account page (myaccount.google.com) and change your password. Never use a link from a suspicious email to do this. - Run the Google Security Checkup: Use the Security Checkup provided by Google (myaccount.google.com/security-checkup). Review all connected devices, app permissions, and recent account activity. Remove any devices you do not recognize and revoke permissions for unknown apps. - Enable two-factor authentication (2FA): If you have not already done so, set up two-factor authentication (2FA). It is the most important additional protective measure for users because attackers cannot access your account with your password alone without the second factor (e.g. a code from your smartphone). In the case of unauthorized demands or extortion attempts: Some phishing emails do not contain links to fake login or account pages. Instead, they make unauthorized demands for money, send fake invoices, or attempt to extort you. In this case: - Do not respond and do not pay: Under no circumstances should you reply to the email or make a payment. Any interaction merely confirms to the attacker that your account is active. - Do not open attachments: Never open attached files such as supposed “lawyer’s letters”, invoices, or payment reminders, as they may contain malware. Report the email as phishing and block the sender: Use Gmail’s reporting function to mark the email as phishing. This helps Google filter similar attacks more effectively in the future and protect other users. Then block the sender. Can companies prevent phishing attacks in Gmail? It is almost impossible to prevent attack attempts altogether because phishing relies on deceiving people. Since malware is generally not sent directly in the email either, filtering at this stage is difficult. The key point is that phishing does not target the technology itself, but the person using it. Companies can, however, drastically reduce the risk through a combination of technical and organizational safeguards and well-trained employees. Google itself already provides a range of powerful Gmail-specific security features that serve as a first line of defense. These include the spam filter and automatic email categorization, as well as visual aids such as blue verification check marks for authenticated senders and prominent red warning banners for emails classified as suspicious. In Google Workspace, this visual support is complemented by the automatic labeling of external emails, helping to raise employee awareness. However, these technical measures are only effective when combined with organizational policies and employee awareness. Company-wide enforcement of strong authentication (MFA/2FA) remains one of the most important barriers for attackers. People as the Decisive Security Layer Even the best technology offers only limited protection if people are not aware of cybercriminals’ methods. As cybersecurity experts, we agree: people are often the last and decisive line of defense. Especially in a corporate environment, one careless click by an employee can have far-reaching consequences.
