Windows Azure Storage Utility Execution Via CLI

Description
This analytic detects the execution of Azure Storage utilities such as AzCopy and Storage Explorer via the CLI. These tools enable large-scale data transfers over trusted cloud channels, allowing malicious activity to blend with legitimate traffic and evade traditional network defenses. Adversaries may leverage them post-compromise to stage or extract sensitive data from endpoints. While legitimate administrative use is expected, anomalous execution patterns, unexpected users, or unusual parent processes should be treated as potential indicators of compromise and investigated promptly.
