Google Workspace Breaches: How Malicious OAuth Apps and Social Engineering Combine for Devastating Results

Google Workspace security is becoming increasingly important as attackers find new ways to breach sensitive information. A live webinar hosted by BleepingComputer on September 23, 2026, will examine two attacks that used malicious OAuth applications and social engineering to gain access to Google Workspace environments.

Rajan Kapoor, Vice President of Security at Material Security, and Rick Fitzgerald, President of Fireside Consulting LLC, will discuss these attacks during the webinar. They will break down how the attackers combined social engineering with malicious OAuth applications to target Google Workspace environments, manipulate users into authorizing application access, and what happens during the first hours of a breach.

The speakers will also cover which security controls provide the greatest value for fast-growing companies with limited security resources and practical security improvements that organizations can implement quickly. These improvements are ranked by effort and potential impact.
