| Verdict: | Malicious activity |
| Threats: | Tycoon 2FA is a phishing-as-a-service (PhaaS) platform designed to bypass multi-factor authentication (MFA) protections, particularly targeting Microsoft 365 and Gmail accounts. Its advanced evasion techniques and modular architecture make it a significant threat to organizations relying on MFA for security. |
