Cybercriminals have been increasingly using a new phishing-as-a-service platform named 'Tycoon 2FA' to target Microsoft 365 and Gmail accounts and bypass two-factor authentication protection.
Tycoon 2FA attacks involve a multi-step process where the threat actor steals session cookies by using a reverse proxy server hosting the phishing web page, which intercepts the victim's input and relays them to the legitimate service.
Stage 0 - Attackers distribute malicious links via emails with embedded URLs or QR codes, tricking victims into accessing phishing pages.
Stage 2 - Background scripts extract the victim's email from the URL to customize the phishing attack.
Stage 6 - Finally, victims are directed to a legitimate-looking page, obscuring the phishing attack's success.
Regarding the scale of operations, Sekoia reports that it's substantial, as there's evidence of a broad user base of cybercriminals currently utilizing Tycoon 2FA for phishing operations.
