1 Million User Records Exposed: A Deep Dive into the Komiko AI App Data Breach

Brandefense analysts identified and validated a high-severity database leak allegedly containing a complete Komiko AI application dump affecting >1,000,000 users; exposed data includes active Google OAuth access and refresh tokens, session tokens, PII (names, emails, profile images), subscription/Stripe IDs, verification tokens, and user-generated content. The report assesses the breach as consistent with a direct database export (dump or compromised backup), highlights immediate risks such as account takeover, cross-platform access via OAuth tokens, phishing and credential-stuffing, and regulatory/reputational impact, and provides prioritized mitigations (revoke OAuth tokens, rotate keys, invalidate sessions, forensic response, and DLP/WAF/DAM controls).
