A new form of phishing attack is leveraging calendar applications to deceive users into compromising their credentials. Fraudsters send calendar invitations via email that automatically populate in services like Google Calendar without requiring user acceptance, creating a sense of legitimacy by appearing alongside legitimate appointments.
These scams take various forms, including fake meetings, service renewal notices, and payment confirmations. The malicious calendar entries typically include descriptions with links to counterfeit login pages or fraudulent phone numbers. Security experts note that scammers sometimes use legitimate platforms such as Zoom to send invitations, making the requests appear more authentic and harder for security filters to identify and block.
Threat detection specialists report that calendar phishing has experienced rapid growth recently. The technique exploits the psychological difference in how users treat calendar entries compared to unsolicited emails. While users may delete suspicious emails without opening them, calendar entries gain credibility by appearing alongside routine appointments like doctor’s visits or work meetings, increasing the likelihood that recipients will click on malicious links or dial fraudulent support numbers.
Experts recommend several defensive measures. Users should disable automatic calendar invitation acceptance and configure settings to only accept invitations from known contacts. When encountering suspicious calendar entries, users should delete or report them as spam rather than clicking decline, which can confirm to scammers that an email address is active. Security professionals emphasize maintaining skepticism toward all calendar invitations, regardless of the apparent sender, treating them with the same caution applied to suspicious emails.
