Microsoft suffered severe outages for some of its services, including Outlook email, OneDrive file-sharing apps, and Azure's cloud computing infrastructure.
The DDoS attacks that targeted the business's services were allegedly carried out by a group going by the name of Anonymous Sudan (also known as Storm-1359).
In a report titled Microsoft Response to Layer 7 Distributed Denial of Service (DDoS) assaults, the IT giant later acknowledged it had been the target of DDoS assaults. Still, he did not disclose further information regarding the outage.
The business emphasized that they had not found proof of unauthorized access to or compromise of client data.
