Tycoon2FA hijacks Microsoft 365 accounts via device-code phishing
Tycoon2FA phishing kit adds device-code attacks to hijack Microsoft 365 accounts via Trustifi URLs.
The Tycoon2FA phishing-as-a-service platform, recently disrupted by law enforcement in March 2026, has rebuilt operations and now supports device-code phishing attacks against Microsoft 365 accounts. The kit abuses legitimate Trustifi click-tracking URLs to redirect victims through multiple obfuscation layers, ultimately tricking them into authorizing attacker-controlled devices via OAuth 2.0 device authorization flows. Device-code phishing attacks have surged 37x this year across at least ten PhaaS platforms, with Tycoon2FA adding advanced anti-analysis protections including 230+ vendor blocklists and debugger timing traps.
