Abuse Info

You can use BARK’s Invoke-AzureRMAKSRunCommand function to execute commands on compute nodes associated with the target AKS Managed Cluster. This function requires you to supply an Azure Resource Manager scoped JWT associated with the principal that has the privilege to execute commands on the cluster. There are several ways to acquire a JWT. For example, you may use BARK’s Get-ARMTokenWithRefreshToken to acquire an Azure RM-scoped JWT by supplying a refresh token:
Now you can use BARK’s Invoke-AzureRMAKSRunCommand function to execute a command against the target AKS Managed Cluster. For example, to run a simple “whoami” command:
If the AKS Cluster or its associated Virtual Machine Scale Sets have managed identity assignments, you can use BARK’s Invoke-AzureRMAKSRunCommand function to retrieve a JWT for the managed identity Service Principal like this:
If successful, the output will include a JWT for the managed identity service principal.

Opsec Considerations

This will depend on which particular abuse you perform, but in general Azure will create a log event for each abuse.
