Nacsa: Microsoft 365 disruption affecting Outlook, Teams likely technical, not cyberattack; agencies told to report issues

KUALA LUMPUR, Nov 13 — The National Cyber Security Agency (Nacsa) believes the recent major global Microsoft 365 service disruption, potentially affecting users worldwide including Malaysia, was more likely due to technical issues rather than a cyberattack. The disruption impacted several key applications such as Outlook, Teams, SharePoint, Microsoft 365 Copilot and Defender XDR, according to Nacsa's statement on its Facebook page.

Government agencies and National Critical Information Infrastructure (NCII) entities were advised to check if their services were affected by the disruption. Nacsa urged all relevant parties to maintain uninterrupted cybersecurity monitoring and stay updated on the latest developments from Microsoft. Additionally, organizations were advised to promptly report any operational disruptions through established reporting channels.
