Security researchers at French firm Sekoia detected a new phishing-as-a-service kit targeting Microsoft 365 accounts in December 2024, the company announced on Jan. 16. The kit, called Sneaky 2FA, was distributed through Telegram by the threat actor service Sneaky Log. It is associated with about 100 domains and has been active since at least October 2024. Sneaky 2FA is an adversary-in-the-middle attack, meaning it intercepts information sent between two devices: in this case, a device with Microsoft 365 and a phishing server. Sneaky 2FA falls under the class of business email compromise attacks. “The cybercriminal ecosystem associated with AiTM phishing and Business Email Compromise (BEC) attacks is continuously evolving, with threat actors opportunistically migrating from one PhaaS platform to another, supposedly based on the quality of the phishing service and the competitive price,” Sekoia analysts Quentin Bourgue and Grégoire Clermont wrote in the firm’s analysis of the attack.
