Analyzing Cloud Storage Exfiltration
Overview
Analyze cloud storage exfiltration patterns across S3, GCS, and Azure Blob services.
Prerequisites
| Requirement | Install |
|---|---|
| Python 3.10+ | For agent tooling |
| Cloud CLI tools | Provider-specific CLIs |
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
- Define investigation scope
- Collect relevant artifacts
- Analyze evidence
- Correlate findings
- Identify indicators
