Device-Code Phishing

The Tycoon2FA phishing kit now supports device-code phishing attacks targeting Microsoft 365 accounts, abusing Trustifi click-tracking URLs, redirecting victims through Cloudflare Workers to a fake Microsoft CAPTCHA page, tricking them into entering a device code, and granting attackers OAuth tokens and access to their Microsoft 365 accounts.

The EvilTokens phishing-as-a-service (PhaaS) platform sold on Telegram is capable of launching device code phishing attacks at scale, leveraging AI to generate convincing and personalized lures, enabling aspiring cybercriminals to bypass traditional security measures, including MFA.

Threat actors are increasingly using device code phishing, often via Phishing-as-a-Service platforms, to compromise user accounts by abusing the OAuth 2.0 device authorization grant flow and capturing authentication tokens, enabling account takeover, data theft, and business email compromise.
