AI-Powered Dynamic Application Security Testing (DAST) -- part of the MEDUSA security platform

STRYX

AI-Powered Dynamic Application Security Testing (DAST)

STRYX is a developer-first, AI-assisted DAST engine that crawls, maps, and tests the live attack surface of web applications. It discovers hidden endpoints, simulates real attacker behavior, and detects exploitable vulnerabilities with minimal false positives. Every finding carries full evidence (request, response, status code, payload, confidence score) -- no heuristic-only results.

Design philosophy: high signal, low noise.

How It Fits Into MEDUSA

• Remy -- SAST, analyzes source code pre-deployment.
• STRYX -- DAST, validates a running application's live attack surface and exploitability.
• MEDUSA -- Aggregates findings from both, correlates static and runtime issues, estimates business impact, provides centralized security management.

Installation

# From PyPI
pip install stryx

# From source
git clone https://github.com/Medusa-Security/stryx.git
cd stryx
pip install -e .

Quickstart

# Run a full scan
stryx scan http://localhost:8000

# Output:
# STRYX Scan Results
# Target: http://localhost:8000
# Total Findings: 3
# Breakdown: CRITICAL: 1 | HIGH: 1 | MEDIUM: 1

Core Modules

Module	Purpose
Endpoint Discovery	Crawls targets, extracts APIs from OpenAPI/Swagger, sitemaps, JS files, GraphQL
Authentication Scanner	Tests missing auth, weak JWTs, session fixation, cookie security
Authorization Scanner	Tests IDOR, privilege escalation, admin access, multi-tenant escape
Injection Engine	SQL, NoSQL, command, SSRF, path traversal, XXE, SSTI, LDAP injection
API Fuzzer	Parameter mutation, boundary values, type confusion, nested JSON
CORS Scanner	Detects misconfigured CORS policies and origin reflection
GraphQL Scanner	Tests introspection exposure, query depth limiting
AI Attack Planner	Constructs multi-step attack chains across findings
Evidence Engine	Enforces evidence requirements on every finding
