Exposure Radar & SaaS OAuth Application Discovery¶

1. Executive Summary & Value Proposition¶

Modern corporate data breaches increasingly occur without a single password being stolen. Instead, attackers trick employees into authorizing malicious or excessive OAuth 2.0 applications (consent phishing or illicit consent grants) that grant permanent, programmatic API access to Microsoft 365, Google Workspace, OneDrive, Google Drive, and corporate mailboxes. SimuPhish’s Exposure Radar & SaaS OAuth Application Discovery continuously audits authorized third-party cloud apps across your enterprise tenants, identifies Shadow IT, flags risky and malicious OAuth tokens, and empowers security teams with 1-Click Token Revocation to neutralize cloud supply chain compromises before data exfiltration begins.

2. The Threat Landscape & The Real-World Problem Solved¶

The Rise of Illicit Consent Phishing: Attackers register fake productivity tools (e.g., "Zoom Schedule Sync", "DocuSign Signature Viewer", "AI PDF Reader"). When an employee clicks "Accept Permissions", the attacker gains persistent API tokens bypassing Multi-Factor Authentication (MFA) and password resets.
Shadow IT Blindspots: Employees frequently connect unvetted third-party productivity and AI tools to enterprise suites without IT knowledge or security vetting.
Invisible Persistence: Revoking an employee's password or cycling their session cookies does not invalidate an active OAuth refresh token. Attackers retain read/write access to corporate email, OneDrive folders, and SharePoint indefinitely until specifically revoked.

3. How It Works (The User Journey)¶

The Administrator Experience¶

Tenant Connectivity: Connect Microsoft Entra ID (Azure AD) or Google Workspace via read-only administrative app consent in under two minutes.
Autonomous Cloud App Inventory: Exposure Radar scans all enterprise app registrations and delegated/application permission grants.
Risk Scoring & Flagging: Identifies high-risk API scopes (e.g., Mail.ReadWrite, Files.ReadWrite.All, offline_access, Directory.AccessAsUser.All), unverified publishers, newly registered tenant apps, and dormant applications.
1-Click Immediate Revocation: Admins can instantly disconnect high-risk apps directly from the SimuPhish console, invalidating refresh tokens and removing tenant permissions.

The Employee Experience¶

Frictionless Routine: Legitimate, IT-approved SaaS tools remain unaffected.
Contextual Security Education: When an employee's authorized app is flagged and revoked, SimuPhish delivers a targeted micro-learning module on "Vetting Third-Party Permissions & Avoiding Consent Phishing".

4. Key Business Benefits & Measurable ROI¶

Eliminate MFA-Bypassing Threat Vectors: Blocks persistent cloud API intrusions that standard identity defenses fail to detect.
Complete Shadow IT Visibility: Instantaneous audit of all third-party integrations running inside your cloud productivity tenant.
Sub-Minute Incident Containment: Reduce OAuth token containment time from hours of complex PowerShell / Graph API scripting to a single button click.
Quantifiable ROI: Avoids cloud forensic investigation fees (averaging \$40,000+ per incident) and eliminates data breach liabilities under GDPR, HIPAA, and SEC disclosure rules.

5. Real-World Attack Scenario & Case Study¶

Attack Vector: An attacker sends an email to a senior financial controller offering early access to a popular AI scheduling assistant.
Exploitation: The controller clicks "Connect with Microsoft 365" and approves the OAuth dialog requesting Mail.Read and Calendars.ReadWrite. The attacker immediately writes an inbox forwarding rule and monitors financial wire instructions.
SimuPhish Interception: SimuPhish Exposure Radar flags the new app registration within minutes: unknown publisher domain registered 48 hours ago, possessing elevated mail access. The SOC receives a high-severity alert, executes 1-Click Revocation, and neutralizes the breach before any financial transaction is manipulated.
