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

Wiz says that this occurred on account of an Azure function referred to as Shared Entry Signature (SAS) tokens, which is “a signed URL that grants entry to Azure Storage information.” The SAS token might have been arrange with limitations to what file or information could possibly be accessed. Nonetheless, this specific hyperlink was configured with full entry.
Including to the potential points, in line with Wiz, is that it seems that this information has been uncovered since 2020.
Wiz contacted Microsoft earlier this 12 months, 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.
