Microsoft has confirmed that its OneDrive and Outlook services experienced disruptions in early June due to cyberattacks orchestrated by a group called Anonymous Sudan, which may have ties to Russia. The group claimed responsibility for the attacks via Telegram, but Microsoft has not provided many details on the nature of the attacks.
