Gmail Phishing Emails: New Sophisticated Attack Exploits Google's Own Systems

Do not open that Google notification! It could be a scam. Gmail phishing emails have reached new levels of sophistication. The cybersecurity team at CyberFlow warns of a recently discovered Gmail phishing scam that has taken deception to new heights.

Hackers learned how to manipulate Google’s own notification system and trusted domains to deliver convincing phishing emails directly to users’ inboxes. Thus, they manage to bypass alss traditional security measures.

How the Gmail Phishing Attack Works

Various security researchers have documented a particularly hard-to-detect Gmail phishing attack. It uses legitimate Google services to create highly convincing fake emails. What makes this Google phishing email scam dangerous is the fact that it mimics communications from Google itself.

The attack begins with threat actors creating a Google account with an address formatted as “me@domain.” They then create a Google OAuth app and place an entire phishing message in the name field of the application.

Using Google’s Own Notification Systems to Deceive Victims

Next, the attackers granted themselves access to the email address in Google Workspace. This triggers Google to automatically send a notification email to the “me@domain” account. Because the phishing message was inserted into the name field, it appears prominently in the notification, filling the entire screen when viewed.

Finally, the attackers forward this legitimate Google-generated email to their intended victims. Since Google itself generated the original email, it comes complete with a valid DKIM signature. This is a digital authentication method designed to verify that an email was indeed sent by the claimed sender and wasn’t altered in transit.

Why These Gmail Phishing Emails Are So Dangerous

This technique, known as a “DKIM replay phishing attack,” represents one of the most sophisticated phishing attacks targeting Gmail users. The CyberFlow specialists know why it is particularly effective:

1. The emails come from a legitimate Google domain ([email protected])
2. They pass standard email authentication checks, including DKIM verification
3. They bypass most spam filters and security tools
4. They appear indistinguishable from genuine Google notifications at first glance.

More technically savvy users might spot something wrong by scrolling to the bottom of the email. This is where text about granting access to “me@domain” appears.

However, the average Gmail user would most probably be deceived by the convincing appearance of the message.

To complete the deception, the attackers host their credential-harvesting pages on sites.google.com. This is Google’s free website creation platform.

Using Google’s own domain for the phishing landing page further reinforces the appearance of legitimacy and helps bypass URL reputation filters that might otherwise flag suspicious domains.

How to Protect Yourself against Gmail Phishing Scams

Even when attackers manage to exploit trusted systems like Google’s, there are steps you can take to protect yourself from these sophisticated phishing attacks:

• Be careful about unexpected notifications about serious business, legal or financial matters, even if they appear to come from legitimate sources
• Always verify important notifications through official channels—log into your Google account directly to check for any actual notifications
• Look for fine clues that something isn’t right—in this case, scrolling to the bottom of the email would reveal text about access to an unfamiliar email address
• Be especially cautious of links to sites.google.com in unexpected contexts—while this is Google’s legitimate domain, it’s frequently abused by attackers due to its trusted status
• Enable two-factor authentication on all accounts to provide an additional layer of protection even if your credentials are compromised.
