Microsoft Blames Recent Cloud Outages on DDoS Attacks.
Microsoft has revealed that the outages of its 365 services and Azure Cloud portal in early June were caused by a distributed denial of service (DDoS) attack orchestrated by Anonymous Sudan. The attack targeted layer 7 rather than layer 3 or 4, and Microsoft has since hardened its layer 7 protections. The company has not linked the DDoS to the attacker, but has suggested that the group "appears to be focused on disruption and publicity." Microsoft has found no evidence that customer data was accessed or compromised.
