## What it is
Sparrow.ps1 is a PowerShell script from CISA's Cloud Forensics team that helps incident responders detect possibly compromised accounts and applications in Azure/Microsoft 365 environments. It checks the unified audit log for indicators of compromise, lists Azure AD domains, and inspects service principals and Graph API permissions, exporting results to CSV files.

## Use cases
- detect compromised accounts in azure m365
- hunt for solarwinds-style identity attacks in my tenant
- audit azure ad service principals and graph api permissions
- check unified audit log for indicators of compromise
- investigate suspicious application activity in office 365
- export m365 audit findings to csv for analysis

## When to choose
- you are an incident responder investigating identity or authentication-based attacks in an Azure/M365 tenant
- you need a read-only sweep of unified audit logs, Azure AD domains, and service principals
- you want CSV outputs you can feed into a dashboard like Aviary or analyze manually

## When to avoid
- you need actively maintained tooling - the repo was archived in December 2022 and is no longer maintained
- you require comprehensive cloud security monitoring beyond the narrow scope of federated identity and application attacks
- your tenant lacks the required E5/G5 license or unified audit logging, which some checks depend on
