SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This skill solves the challenge of tracking security posture changes over time by comparing multiple recon datasets to identify new vulnerabilities, regressions, and persistent findings.

Core Features & Use Cases

  • Delta Reporting: Automatically compares findings between two recon waves to highlight changes in infrastructure or security status.
  • Regression Detection: Identifies when previously open vulnerabilities have been hardened or blocked.
  • Surface Expansion Tracking: Detects newly exposed ports, subdomains, or services that appeared since the last scan.

Quick Start

Run the cross-wave-delta-analysis skill by providing the paths to your old and new recon output directories to generate a comparative delta report.

FAQPage Schema
What is recon delta analysis and when do I need it for pentest workflows?

Recon delta analysis compares structured findings across multiple temporal scan waves to identify security regressions and new attack surfaces. You need it when tracking target infrastructure changes and vulnerability persistence over time during offensive security assessments.

How do I compare two recon datasets to detect new vulnerabilities?

To compare recon datasets for new vulnerabilities, provide the paths to your old and new standardized markdown recon output directories. The tool generates a comparative delta report highlighting infrastructure changes, regressions, and newly exposed ports or subdomains.

Do I need Python 3 to run cross-wave security drift detection?

Yes, Python 3 is required to run cross-wave security drift detection. You also need access to standardized markdown-based recon output files from your previous scanning waves to perform the longitudinal infrastructure analysis.

Can I track newly exposed subdomains and ports between scan waves?

Yes, you can track newly exposed subdomains and ports between scan waves. The surface expansion tracking feature detects new services and infrastructure changes that appeared since your last scan, highlighting them in the delta report.

What's the best way to identify security regressions in target infrastructure?

The best way to identify security regressions is comparing temporal recon waves to check if previously open vulnerabilities have been hardened or blocked. This longitudinal analysis tracks persistence and flags when security posture weakens over time.

What format must recon output files be in for delta comparison?

Recon output files must be in a standardized markdown format for delta comparison. The analysis scripts parse these markdown files from your provided directories to detect security drifts and generate comparative reports.
