Local Token Storage and Security Considerations
Azure CLI (Command-Line Interface)
Tokens and sensitive data are stored locally by Azure CLI, raising security concerns:
Access Tokens: Stored in plaintext within
accessTokens.jsonlocated atC:\Users\<username>\.Azure.Subscription Information:
azureProfile.json, in the same directory, holds subscription details.Log Files: The
ErrorRecordsfolder within.azuremight contain logs with exposed credentials, such as:Executed commands with credentials embedded.
URLs accessed using tokens, potentially revealing sensitive information.
Azure PowerShell
Azure PowerShell also stores tokens and sensitive data, which can be accessed locally:
Access Tokens:
TokenCache.dat, located atC:\Users\<username>\.Azure, stores access tokens in plaintext.Service Principal Secrets: These are stored unencrypted in
AzureRmContext.json.Token Saving Feature: Users have the ability to persist tokens using the
Save-AzContextcommand, which should be used cautiously to prevent unauthorized access.
Automatic Tools to find them
Security Recommendations
Considering the storage of sensitive data in plaintext, it's crucial to secure these files and directories by:
Limiting access rights to these files.
Regularly monitoring and auditing these directories for unauthorized access or unexpected changes.
Employing encryption for sensitive files where possible.
Educating users about the risks and best practices for handling such sensitive information.
