The Federal Bureau of Investigation (FBI) is issuing this Public Service Announcement (PSA) to warn the public about an emerging Phishing¹-as-a-Service² (PhaaS) platform called Kali365, first seen in April 2026. Kali365 has primarily been distributed via Telegram, enabling cyber threat actors to obtain Microsoft 365 access tokens and bypass multi-factor authentication³ (MFA) protocols without intercepting the user's credentials.

Through the Kali365 platform subscription, cyber threat actors can capture "OAuth" tokens and gain persistent access to targeted individuals/entities' Microsoft 365 environments. Kali365 lowers the barrier of entry, providing less-technical attackers access to AI-generated phishing lures, automated campaign templates, real-time targeted individual/entity tracking dashboards, and OAuth token capture capabilities.
