Cybercriminals have devised a new tactic to deceive unsuspecting users by sending fake Google Calendar invites. These invites cleverly masquerade as genuine notices from reputable organizations, fooling recipients into handing over personal information and credentials. This sophisticated scam relies on the manipulation of email headers, which makes the messages appear as though they originate from trustworthy entities, such as well-known companies or acquaintances.
The bait typically involves a Google Calendar invite, which ultimately directs the unsuspecting individual to a website designed to harvest sensitive data or solicits them to disclose financial details. These deceptive ploys have seen a surge in recent weeks, with cybersecurity researchers reporting that approximately 4,000 such emails have been dispatched over a month, spoofing more than 300 distinct brands.
As email scanning technologies, like those in Gmail and Microsoft Outlook, started catching wind of these scams, the fraudsters shifted their strategies. The malicious links can now redirect victims to cunningly disguised Google Forms, Google Drawings, or even fake ReCaptcha pages. The ultimate objective remains unchanged: to lead trusted recipients to a page where sensitive information can be stolen.
In light of these scams, Google has advised users to make use of Gmail’s built-in filtering rules and enable the “known senders” setting. This proactive step can help prevent potential victims from even opening such malicious emails. Until more robust security measures are in place, staying vigilant and only interacting with links from trusted and anticipated sources is crucial for protecting oneself from these kind of exploits.
