Microsoft 365 Disruption Caused by Technical Issues, Not Cyberattack – NACSA

KUALA LUMPUR: The Microsoft 365 service disruption, which could potentially affect users worldwide, including Malaysia, has been confirmed to be caused by technical issues rather than a cyberattack.

The National Cyber Security Agency (NACSA), in a Facebook post, said the disruption involved key applications, including Outlook, Teams, SharePoint, Microsoft 365 Copilot and Defender XDR.

“Based on current information, the disruption is more likely to have been caused by technical or infrastructure issues rather than a cyberattack,” the post stated.

Following this, the National Cyber Coordination and Command Centre (NC4) under NACSA advised all government agencies and National Critical Information Infrastructure (NCII) entities to check the status of their affected services.

“All relevant parties are urged to ensure that cybersecurity monitoring remains uninterrupted and to stay updated with the latest developments from Microsoft,” the post stated.

NACSA also urged organisations to immediately report any operational disruptions through existing reporting channels.
