Abstract:
Azure Policy is a built-on service that helps creating security and compliance policies to enforce organizational standards in the cloud environment. It evaluates resources by comparing the properties of the resources and with the help of remediation tasks, it can fix or remediate any issues with those resources. Have you ever wondered if you could abuse or bend these policies? Can you do more than just listing the storage accounts with public access and not be in the logs? How about creating a backdoor?
In this talk I will answer these questions by talking about what Azure Policy is, how to write one, what the logs contain, what permission you need, what does resource enumeration could look like etc. At the end I will present a proof-of-concept solution to bend the Azure Policy and create a backdoor account in Azure.
