Hackers Still Exploiting Google Calendar in Phishing and Malware Attacks

Wired reports that Google Calendar, the widely used scheduling tool, is still a target for cybercriminals. Attempts to exploit users through deceptive invitations and embedded malware links are increasing.

Hackers leverage Google Calendar’s credibility to distribute phishing scams and malware. The app’s ubiquity and integration with daily workflows assures a large pool of unsuspecting users, some of whom fall victim to these schemes. They use various tactics, including embedding phishing links in event descriptions, emails, or attached files.

A notable attack, identified by cybersecurity firm Check Point, involved spoofing a genuine Google Calendar invite over email. Any response to the invite leads to a reCAPTCHA form or support button. The target is prompted to enter personal details on an official-looking site. Those can then be used to access other accounts or make unauthorized purchases.

Though Google has patched some vulnerabilities, past attempts, such as using event descriptions for remote access exploits, highlight the evolving nature of such threats.

Google continues to enhance security measures. Its Calendar app is regularly updated with new protections, and ensuring that users’ apps and web browsers are up to date is a proven method of staying protected against the latest attacks.

Users should be cautioned to be suspicious of anything that comes into their inbox with an embedded link, even if it says it’s from Google Calendar. Instruct them not to go any further if a link leading somewhere other than Google Calendar is discovered.

This issue underscores the importance of cybersecurity awareness for lawyers in professional settings. Legal teams handling sensitive data should educate employees on identifying phishing attempts, implement two-factor authentication, and regularly audit app permissions.

Reviewing metadata in email invitations and confirming invites directly with senders can help prevent malware that leads to data breaches. Law departments might also consider cybersecurity training to mitigate risks associated with digital scheduling tools.
