Cyberattacks Target Microsoft's Outlook and Cloud Platform in Early June.

Microsoft has confirmed that the early June disruptions to its flagship office suite, including Outlook email and OneDrive file-sharing apps, and cloud computing platform were caused by distributed denial-of-service (DDoS) attacks by a group called Anonymous Sudan. The attackers used rented cloud infrastructure and virtual private networks to bombard Microsoft servers from botnets of zombie computers around the globe. Microsoft said there was no evidence any customer data was accessed or compromised. The attacks were focused on disruption and publicity, and it is not clear how many customers were affected or whether the impact was global.
