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) has stated that a widespread Microsoft 365 service disruption, likely impacting users worldwide, including Malaysia, is more likely to be caused by technical or infrastructure problems rather than a cyberattack. The disruption affected several crucial applications such as Outlook, Teams, SharePoint, Microsoft 365 Copilot and Defender XDR.

Nacsa advised all government agencies and National Critical Information Infrastructure (NCII) entities to verify if their services were compromised. The agency urged all relevant parties to ensure continuous cybersecurity monitoring and to stay informed about the latest developments from Microsoft. Additionally, Nacsa called upon organizations to promptly report any operational disruptions through designated channels.
