Microsoft says the early June 2023 disruptions to its Microsoft’s flagship office suite — including the Outlook email and OneDrive file-sharing apps — were denial-of-service attacks by a shadowy new hacktivist group.

Initially reticent to name the cause, Microsoft has now disclosed that DDoS attacks by the murky upstart were indeed to blame. On Twitter that day, Microsoft said Outlook, Microsoft Teams, SharePoint Online and OneDrive for Business were affected. Attacks continued through the week, with Microsoft confirming on June 9 that its Azure cloud computing platform had been affected.
