Malware infiltrates Google Calendar

Cybercriminals are now using Google Calendar to spread malware, with recent reports warning users of phishing attempts that could compromise sensitive information.

What happened 

Malicious actors are targeting Google users by sending fake meeting invites embedded with phishing links. These links, often disguised as legitimate event details, can be placed in event descriptions or attached as .ics files, which automatically integrate into a user's calendar. Once clicked, they may lead to credential-stealing sites, putting emails, chat logs, browser data, and login credentials at risk.

What was said

Wired detailed how scammers manipulate Google Calendar's invitation features to appear legitimate: “A standard Google Calendar invite comes with links to both the event itself and the list of guests — the event is also included as an .ics file attachment to open in a calendar app.” The publication further warned that “events themselves, meanwhile, can come with links embedded in the description and files from Google Drive attached. All of these elements can be taken advantage of in some way by bad actors.”

To avoid falling victim to these scams, Wired advises users to be cautious: “Even if you think you are on Google Calendar, double-check the browser address bar to make sure.” They also stress the importance of verifying the sender’s email before responding to event invites or clicking links. 

Why it matters

With over 500 million users per month on Google Calendar, this data breach makes users vulnerable to sophisticated phishing attempts. Falling for one of these scams could expose sensitive business and personal data, leading to potential financial loss, identity theft, or unauthorized access to private communications.
