Tycoon2FA

Tycoon2FA is a dangerous phishing-as-a-service (PhaaS) toolkit that enables cybercriminals to bypass multi-factor authentication (MFA) by hijacking session cookies during login processes. Using advanced adversary-in-the-middle (AiTM) techniques, it impersonates legitimate login portals—such as Microsoft 365 and Gmail—to capture both credentials and authentication tokens in real time. With obfuscated code, anti-debugging features, and clipboard restrictions, Tycoon2FA is engineered for stealth and evasion. It’s widely sold on underground forums and increasingly used in targeted attacks, making it a major threat to enterprise security in 2025.
