So, how did this occur? The report explains that Microsoft’s AI staff uploaded a bucket of coaching knowledge containing open-source code and AI fashions for picture recognition. Customers who got here throughout the Github repository have been supplied with a hyperlink from Azure, Microsoft’s cloud storage service, to be able to obtain the fashions.

Nonetheless, this specific hyperlink was configured with full entry.

Including to the potential points, in response to Wiz, is that it seems that this knowledge has been uncovered since 2020.

Wiz contacted Microsoft earlier this yr, on June 22, to warn them about their discovery. Two days later, Microsoft invalidated the SAS token, closing up the problem. Microsoft carried out and accomplished an investigation into the potential impacts in August.

Microsoft supplied TechCrunch with a assertion, claiming “no buyer knowledge was uncovered, and no different inner providers have been put in danger due to this subject.”
