OAuth Consent Screen Risk Analyzer Browser Extension
A browser extension that detects Google OAuth consent screens in real time, analyzes the requested scopes against what the requesting service legitimately needs, and warns users with a clear risk assessment before they grant access—particularly flagging advertising account permissions during job-application or booking flows.
Why this matters
You are a digital marketer or PPC professional who receives recruiting emails that look legitimate. A fake company website shows realistic job postings and invites you to book an interview through what appears to be a standard Google authentication flow. The OAuth consent screen looks completely normal—same layout, same branding, same button styles. Unless you carefully read every scope being requested, you would never realize you are granting access to your Google Ads account rather than booking an interview. Fresh graduates eager for their first break are especially vulnerable. Once access is granted, the attacker can silently modify your ad campaigns, drain budgets, or use your account for fraudulent ads. You currently have no tool that watches your back during that consent flow—you must manually scrutinize scopes and hope you catch the red flag.
- · Built for PPC professionals, digital marketing agencies, and technically aware job seekers who manage Google Ads accounts and want proactive protection against OAuth-based account takeover scams.
- · Most likely monetization: freemium.

Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Google may already be planning improved native OAuth warnings that would make the extension redundant—platform risk is significant since Google controls the consent UI
- 2User acquisition for a security extension is notoriously difficult because people install protections only after being harmed, not proactively, limiting organic growth
- 3False positives on legitimate marketing tools could trigger backlash from the SaaS tools whose OAuth flows are incorrectly flagged, creating legal and reputational risk
Evidence Summary
How AI synthesized this insight — no verbatim quotes
Approximately 4 commenters explicitly described how the OAuth consent screen appears completely normal and indistinguishable from legitimate flows, with particular emphasis on how rushing or not reading specific scopes leads to compromise. Multiple users noted the scam site had been live for an extended period without detection. One commenter provided detailed post-compromise remediation steps, confirming there is no automated tooling for this today. The community moderator expressed strong desire to reduce scam effectiveness, suggesting institutional willingness to promote protective tools.
