Gmail has issued a security alert to its 2.5 billion users regarding a sophisticated AI-driven phishing attack that has been confirmed to target account credentials. The attack uses artificial intelligence to generate highly convincing emails and phone calls that appear to originate from Google support services, marking a significant evolution in AI-powered phishing threats that have impacted 96 percent of organizations in 2024.
The phishing campaign operates through a dual-channel approach. Users receive calls from numbers displaying Google caller ID, with individuals claiming to represent Google’s support team. These callers inform users that their accounts have been temporarily suspended due to suspicious activity. Subsequently, users receive seemingly legitimate emails from what appears to be an authentic Google domain to corroborate the supposed security issue. The multi-channel attack strategy reflects recent trends in identity fraud, which has seen a 42 percent increase in 2024.
To enhance credibility, the attackers often instruct users to verify the authenticity of the initial contact by calling back a provided number. The technique serves to build trust with potential victims before attempting to harvest their credentials, similar to tactics observed in recent sophisticated Google account phishing campaigns that have resulted in substantial cryptocurrency losses.
“Very clever,” said Zach Latta, founder of Hack Club, who encountered but identified the attack, while emphasizing that it remains preventable through proper vigilance.
Google has recommended several security measures to combat these sophisticated phishing attempts. Users are advised to enable the ‘Only If The Sender Is Known’ setting in Google Calendar, which generates alerts when receiving invitations from unknown contacts. The implementation of multi-factor authentication (MFA) provides an additional security layer for account protection, particularly important given Google’s recent efforts to strengthen account security through features like Restore Credentials for Android devices.
Security experts advise users to exercise caution regarding communications that demand immediate action, particularly those claiming to originate from support teams. Legitimate Google support rarely requires users to provide sensitive information over phone calls or to verify their identity through callback numbers.
Standard security practices remain essential: users should verify sender email addresses, examine messages for spelling errors, hover over links to check URLs before clicking, and maintain skepticism toward unexpected communications requesting account credentials or personal information. The basic precautions become increasingly crucial as phishing attacks continue to evolve with advancing AI technology.
