“We detected uncommon exercise with a small variety of inner accounts and upon assessment, we found one account had been used to view supply code in various supply code repositories,” the Home windows maker had beforehand disclosed.
“The account didn’t have permissions to switch any code or engineering programs and our investigation additional confirmed no modifications had been made. These accounts had been investigated and remediated.”.
Now according to the corporate, moreover viewing few particular person information by looking by the repositories, some instances concerned downloading element supply code associated to —
- a small subset of Azure elements (subsets of service, safety, id)
- a small subset of Intune elements
