O

QR-SHIELD is a research-grade Python framework for analyzing QR-code-related security risks and supporting defensi. It helps security researchers, detection engineers, and defensi study QR-code threat scenarios, develop methods, and impro of emerging risks in the QR ecosystem.

Core Mission: Translate security research into practical defensi.

This project is built for:

Project Philosophy

QR-SHIELD operates on the principle that understanding relevant threat patterns is essential to building effecti. By studying how QR codes can be abused in controlled research settings, the project supports stronger detection systems, impro, and more resilient security implementations.

Threat Model

QR-SHIELD implements research into the following threat scenarios:

1. Session Exposure via QR Code

- Observing acti during QR-based authentication

- E secondary controls

1. Credential Exposure Analysis

- Re exposure paths from captured sessions

- Understanding token management risks

1. Post-Exposure Assessment

- E behavior after session exposure

- Understanding platform response patterns

1. Attack Surface Analysis

- Identifying QR-specific security considerations

- Documenting platform-specific weaknesses

See THREAT_MODEL.md for complete threat analysis.

Security Considerations

Design Principles

1. Isolation: Research acti should be conducted in isolated, controlled en

1. : Operations should be traceable and auditable

1. Containment: No persistent changes to systems under e

1. Consent: Only use against systems you own or ha authorization to test
