The FBI released an urgent security warning to the public about a fast-acting scam targeting Microsoft 365 users on Teams, Outlook and OneDrive. The agency warned that the hacking platform Kali365 seeks out OAuth device codes, allowing scammers to sneak past multi-factor authentication codes, and without the need for a password, to access Microsoft accounts. Scammers will send a phishing email impersonating a trusted document-sharing service with a device code and instructions on how to verify, according to the FBI.

"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," the FBI stated. The platform is sold to scammers with a $250 per month subscription. The FBI, which first detected Kali365 in April, described the hacking platform as an "emerging Phishing-as-a-Service platform." Hackers with limited skills can access advanced phishing tools through the platform, according to NordPass.

Sure glad I ditched windows/microsoft decades ago.
