Analyzing Cloud Storage Exfiltration

Overview

Analyze cloud storage exfiltration patterns across S3, GCS, and Azure Blob services.

Prerequisites

Key Concepts

Analyzing Cloud Storage Exfiltration involves systematic analysis and investigation of security events in the target environment.

Quick Reference

node scripts/agent.js discover --target <TARGET>
node scripts/agent.js analyze --target <TARGET> --depth full
node scripts/agent.js collect --target <TARGET> --output evidence.json
node scripts/agent.js report --investigation INV-001

Workflow

1. Define investigation scope
2. Collect relevant artifacts
3. Analyze evidence
4. Correlate findings
5. Identify indicators
6. Document chain of custody
7. Generate report
