Core Features

Fully Autonomous Operation

Shannon operates independently, handling 2FA, browser navigation, exploitation, and report generation without manual intervention.

Source: Features per README
Reproducible Proof-of-Concept Exploits

The tool provides only proven findings with PoCs, ensuring that vulnerabilities are exploitable and actionable.

Source: Features per README
OWASP Vulnerability Coverage

Shannon identifies and validates common web application vulnerabilities such as injection, XSS, SSRF, and broken authentication.

Source: Features per README
Code-Aware Dynamic Testing

The tool analyzes source code to guide attack strategies and validates findings with live browser and CLI-based exploits.

Source: Features per README
Integrated Security Tooling

Shannon leverages various security tools like Nmap, Subfinder, WhatWeb, and Schemathesis for reconnaissance and discovery.

Source: Features per README
Parallel Processing

Vulnerability analysis and exploitation phases run concurrently across all attack categories for efficiency.

Source: Features per README

Architecture

The architecture is modular, with separate components for static code analysis, dynamic testing, and report generation. It uses a Code Property Graph for static analysis and parallel processing for dynamic testing. Key technical decisions include the use of LLMs for reasoning and the integration of various security tools.
