FBI Warning for Microsoft 365 Users
If your business uses Microsoft Teams, Outlook, OneDrive, or Microsoft 365, this is something you need to pay attention to.
The FBI recently issued a warning about a new phishing platform called “Kali365” that allows cybercriminals to gain access to Microsoft 365 accounts WITHOUT stealing a user’s password. Instead, attackers trick users into approving access through a legitimate Microsoft authentication process, bypassing traditional security measures and even Multi-Factor Authentication (MFA) in some cases.

What makes this attack dangerous?

No password theft required
Uses legitimate Microsoft verification pages
Can provide attackers access to Outlook, Teams, OneDrive, and other Microsoft 365 services once approved. (Fast Company)
Business owners should immediately:
🔹 Train employees to recognize phishing attempts and unexpected authentication requests.
🔹 Review Microsoft 365 Conditional Access policies.
🔹 Audit third-party application permissions and OAuth access.
🔹 Monitor sign-in activity for unusual locations or devices.
🔹 Ensure Microsoft 365 security settings are properly configured and continuously monitored. (TechRadar)
