🔴 Critical: Webinar: How Google Workspace breaches happen and what to do next

[XploitLK-Bot]

Most Google Workspace compromises don’t start with a clever exploit or zero-day. Instead, they typically begin with social engineering—phishing, credential theft, or session hijacking—or with forgotten third-party integrations that retain excessive permissions long after they’re needed.

The webinar walks through real-world breach scenarios, focusing on what occurs in the critical first hours after an attacker gains access. That early window often determines whether an incident stays contained or spirals into full account takeover, data exfiltration, or lateral movement across connected services.

Key technical points covered include:

• The role of OAuth applications and legacy integrations in providing persistent, hidden access to Workspace data.
• How attackers use session tokens and cookies to bypass MFA (multi-factor authentication) after an initial login.
• The importance of auditing delegated admin roles and API scopes, since many breaches exploit over-privileged accounts.
• Detection gaps in default Workspace logging—specifically, which logs (like login challenges or Gmail message search events) are not enabled by default.

The discussion also emphasizes practical controls that make the biggest impact: enforcing hardware-key-only MFA, restricting third-party app access via allowlisting, and setting up custom alerts for unusual admin actions or impossible travel patterns. The earlier you identify abnormal behavior, the more likely you can revoke access before damage spreads.

Given how often these breaches rely on stale OAuth permissions, how is your organization tracking and revoking access for legacy third-party apps in Workspace?
