Managed Identity Token Used to Access Azure Key Vault Secrets
Detects potential misuse of an Azure Managed Identity token on a Linux host, where 'curl' is used to interact with the Azure Key Vault API (vault.azure.net/secrets) while presenting an Authorization bearer token. This pattern can indicate an adversary who has obtained a Managed Identity token (e.g., via the Instance Metadata Service) and is attempting to exfiltrate or access sensitive secrets stored in Azure Key Vault.
