Identifies retrieval of Azure VM boot diagnostics data ("MICROSOFT.COMPUTE/VIRTUALMACHINES/RETRIEVEBOOTDIAGNOSTICSDATA/ACTION") by an identity that has not performed this operation recently. Boot diagnostics expose the VM serial console log and a console screenshot, which frequently contain plaintext boot-time output such as credentials, tokens, cloud-init/agent secrets, and command history. An adversary with VM read/contributor rights can retrieve this data over the control plane, without logging into the guest or touching the network, to harvest credentials.
