This video demonstrates a detailed hacking scenario where the presenter exploits Azure Managed Identities to gain unauthorized access to cloud resources. Here are the critical points covered in the video:
- 🌐 Initial Access and Exploitation: The presenter begins by exploiting a vulnerability in a PHP-powered Azure website, allowing the upload of a malicious PHP webshell. This shell facilitates the execution of arbitrary code on the Azure virtual machine hosting the website.
- 🔑 Escalation and Persistence: Using the webshell, the presenter accesses sensitive environment variables, including Azure service management tokens and identity endpoints, crucial for accessing further Azure services.
- 🔧 Leveraging Azure Identity:
- Managed Identities: The presenter explains how Azure Managed Identities work, providing Azure services with an automatically managed identity in Azure Active Directory. This identity is used to authenticate to services that support Azure AD authentication.
- Token Acquisition: Demonstrates acquiring an Azure service management token, which is then used to interact with Azure’s management layer.
- 💻 Azure Management and Command Execution:
- Azure PowerShell: Utilizes Azure PowerShell modules to interact with the cloud environment programmatically.
- Virtual Machine Control: Executes commands remotely on the compromised Azure virtual machine to further manipulate cloud resources.
- 🛡️ Security Implications:
- Extraction of Secrets: Details the method for extracting secret keys and tokens from environment variables and Azure managed identity configurations.
- Unauthorized Actions: Shows how to perform unauthorized actions such as running commands and manipulating Azure resources.
- 0:00: ️Identifying vulnerability in Azure website, compromising access token for managed identity, and extracting credentials from virtual machine.
- 4:17: ️Exploring Azure environment variables for potential access to managed identity tokens.
- 8:51: Exploring Azure authentication using JWT tokens and connecting to Azure account via Powershell.
- 12:44: Setting up parameters for making requests using Powershell commandlet invoke restmethod.
- 17:18: Exploring Azure resources and potential access permissions through script analysis.
- 21:20: Exploiting vulnerabilities in cloud managed identities to gain unauthorized access and control.
- 25:40: Accessing a virtual machine on the cloud using PowerShell session and credentials.
