FBI warns of Kali365 phishing-as-a-service after April Microsoft 365 attacks
The law enforcement agency published an advisory on Thursday about Kali365 — a Telegram-based service for cybercriminals that allows them to capture legitimate "OAuth" tokens enabling widespread access to Microsoft 365 environments.
The FBI warning comes after widespread attacks impacting Microsoft 365 environments, indicating a current and active threat landscape facilitated by new cybercrime services.
Sophisticated phishing-as-a-service offerings like Kali365 represent an industrialization of cybercrime, enabling broader and more effective attacks against critical enterprise infrastructure.
The barrier to entry for conducting advanced phishing attacks has been lowered significantly, allowing more actors to bypass traditional multi-factor authentication methods via stolen OAuth tokens.

- · Microsoft 365 users
- · Organizations with inadequate cybersecurity protocols
Increased successful breaches of Microsoft 365 accounts and subsequent data exfiltration or system compromise.
Accelerated adoption of advanced authentication methods and security tools beyond basic MFA, such as FIDO2 keys or continuous adaptive authentication.
Potential for regulatory response, mandating higher security standards for cloud productivity suites due to systemic risk from widespread compromise.
