Sneaky 2FA

Also known asSneaky 2FA

Sneaky 2FA is a phishing-as-a-service (PhaaS) kit identified as an aggressive newer entrant in the MFA-bypass phishing ecosystem. Reporting cited it as one of the groups that benefited from the disruption of Tycoon 2FA, with monthly attack volume reportedly rising from under 700,000 to nearly 2 million around that period. Barracuda described it as one of the phishing kits that moved quickly to fill the gap left by Tycoon 2FA. Sneaky 2FA uses adversary-in-the-middle (AitM) techniques to bypass multi-factor authentication. Reported capabilities include validating stolen credentials through legitimate Microsoft APIs, evading bots and sandboxes, using browser-in-the-browser fake login windows, and redirecting victims to Microsoft-related pages to reduce suspicion. The provided content does not attribute Sneaky 2FA to a specific nation state or identify additional aliases or sub-groups beyond the name Sneaky 2FA.
