Google Calendar, a tool with over 500 million active users across 41 languages, is widely regarded for its convenience and efficiency in time management. However, its massive popularity has also made it an attractive target for cybercriminals. Recently, these malicious actors have begun exploiting Google Calendar and Google Drawings to orchestrate phishing attacks, raising significant concerns about email security.
In this blog, we’ll explore how hackers are leveraging these trusted tools, their tactics, and how organizations and individuals can protect themselves from these sophisticated attacks.
How Cybercriminals Exploit Google Calendar and Drawings
Cybercriminals are increasingly targeting Google Calendar’s user-friendly features to trick users into falling for phishing scams. According to cybersecurity researchers at Check Point, attackers are using legitimate-looking Calendar invites and Google Drawings links to manipulate users and access sensitive data.
Phishing Emails with Manipulated Sender Headers
Hackers modify sender headers in phishing emails, making them appear as though they are sent from Google on behalf of trusted contacts. These emails often contain:
- Calendar invites that link to malicious websites.
- Fake support or action buttons disguised as legitimate requests.
This technique has already impacted around 300 brands, with over 4,000 phishing emails identified in just four weeks.
Evolution of the Attack Strategy
Initially, attackers exploited Calendar invites by embedding malicious Google Forms links. As cybersecurity measures began identifying these threats, the attackers pivoted to using Google Drawings.
In these newer tactics, phishing emails contain links to Google Drawings with embedded malicious redirects. These redirects lead unsuspecting users to fraudulent websites mimicking cryptocurrency platforms or tech support pages.
Techniques Used in Google Calendar and Drawing Exploits
The phishing attacks typically unfold in stages, making them harder to detect.
- Initial Contact: A phishing email is sent with a Calendar invite (.ics file) or a link to Google Drawings.
- User Action: Users are prompted to click on links within the invite or Drawing.
- Redirect to Fraudulent Sites: Clicking the links redirects users to fake websites designed to steal personal data.
- Data Harvesting: These fake sites request authentication details, payment information, or other sensitive credentials.
These attacks aim to steal data for financial fraud, unauthorized transactions, and bypassing account security.
Protecting Against Google Calendar and Drawing Phishing Attacks
To defend against these emerging threats, organizations and individuals must implement proactive cybersecurity measures.
For Organizations
- Advanced Email Security Solutions
Tools like Harmony Email & Collaboration can identify and prevent phishing attempts by scanning attachments, checking URL reputations, and using AI-based anomaly detection. - Monitor Third-Party Apps
Cybersecurity tools that track and flag suspicious activities in apps connected to Google accounts are essential. - Implement Multi-Factor Authentication (MFA)
MFA adds a critical layer of security. Combining this with behavioral analytics tools can help detect unusual login attempts or interactions with malicious links.
For Individuals
- Be Vigilant with Calendar Invites
Treat unexpected invites with caution, especially those requesting unusual actions like completing a CAPTCHA or clicking urgent links. - Verify Links Before Clicking
Always hover over links to preview their destination. If uncertain, type the URL directly into a browser. - Enable Two-Factor Authentication (2FA)
Activate 2FA for all Google accounts to prevent unauthorized access even if credentials are compromised. - Utilize Google’s “Known Senders” Feature
Google Calendar’s “Known Senders” setting alerts users to invitations from unfamiliar contacts, providing an extra layer of protection.
How Google is Addressing the Issue
Google acknowledges the growing concern and encourages users to enable the “Known Senders” feature in Calendar. This setting alerts users to suspicious invitations, helping them identify and avoid phishing attempts.
The tech giant also emphasizes the importance of adopting advanced email security solutions like Harmony Email & Collaboration to mitigate risks.
Real-World Implications of These Attacks
Cybercriminals are constantly refining their tactics. Phishing campaigns using Google tools are more than just a nuisance; they pose significant risks to both personal and corporate data.
By leveraging tools like Google Calendar and Drawings, hackers exploit the trust users place in these platforms, making it crucial for everyone to stay informed and take proactive security measures.
