Traficomi advises users to be vigilant against suspicious communications requesting sensitive information. The warning emphasizes the importance of recognizing and avoiding phishing attempts. Users are encouraged to report any suspected incidents to the National Cyber Security Centre promptly. This surge in attacks signals a heightened cybersecurity risk for organizations and individuals relying on Microsoft 365 services in Finland.
