New MFA-bypassing phishing kit targets Microsoft 365, Gmail accounts

By Bill Toulas, Bleeping Computer

Cybercriminals have been increasingly using a new phishing-as-a-service (PhaaS) platform named 'Tycoon 2FA' to target Microsoft 365 and Gmail accounts and bypass two-factor authentication (2FA) protection.

Tycoon 2FA was discovered by Sekoia analysts in October 2023 during routine threat hunting, but it has been active since at least August 2023, when the Saad Tycoon group offered it through private Telegram channels.

The PhaaS kit shares similarities with other adversary-in-the-middle (AitM) platforms, such as Dadsec OTT, suggesting possible code reuse or a collaboration between developers.

In 2024, Tycoon 2FA released a new version that is stealthier, indicating a continuous effort to improve the kit. Currently, the service leverages 1,100 domains and has been observed in thousands of phishing attacks.
