Microsoft says early June service outages were cyberattacks

Microsoft said on Friday that the outages that affected certain services of the company through some of the earlier days of this month were the result of cyberattacks, but said it saw no evidence of any customer data being accessed or compromised.

“Beginning in early June 2023, Microsoft identified surges in traffic against some services that temporarily impacted availability'” the company said in a blog post.

Microsoft said it opened an investigation and began tracking the DDoS activity by the threat actor it refers to as Storm-1359 after it identified the threat.
