Unraveling the Origin of June's Service Interruptions

Microsoft (NASDAQ: MSFT) clarified on Friday that cyberattacks caused the intermittent outages observed across several of its services in early June. Despite these assaults, the company confirmed that there was no evidence suggesting customer data was accessed or compromised during these episodes.
