RTPI: An Intelligent Offensive and Defensive Security Platform Based on Fine-tuned Qwen Model

The RTPI project is an agentic intelligent offensive and defensive security platform built on the fine-tuning technology of Alibaba Cloud's Qwen large model. It aims to deeply integrate the reasoning capabilities of large models with cybersecurity expertise, providing security personnel with support for core capabilities such as penetration testing, vulnerability analysis, and secure coding, and promoting the development of the offensive and defensive security domain toward automation and intelligence.

Traditional offensive and defensive security relies on expert experience, which limits efficiency. The introduction of AI technology has changed this landscape, leading to the emergence of the RTPI project. By fine-tuning the Qwen model, it builds an intelligent agent platform tailored to offensive and defensive needs, enabling the model to perform better in understanding security concepts, generating attack payloads, analyzing vulnerability exploitation, etc., and providing AI-assisted tools for security personnel.

Technical Path: The Qwen model is selected (excellent in code understanding/generation, sufficient open-source customization space, good Chinese support). Three-stage training is adopted: 1. Continuous pre-training on security domain corpora to master basic knowledge; 2. Instruction fine-tuning to train execution of specific security tasks; 3. RLHF to optimize output quality and security. Training data covers diverse sources such as CVE databases, ExploitDB, and CTF problems.

Agentic Architecture: Composed of professional agents such as reconnaissance, scanning, exploitation, and reporting. They collaborate via a message bus (e.g., reconnaissance triggers scanning, scanning discovers vulnerabilities and triggers exploitation), and process automation improves efficiency. The architecture has built-in permission verification, audit logs, and sandbox mechanisms to ensure security.

RTPI includes four core functions:

1. Intelligent Reconnaissance and Information Collection: Automatically performs subdomain brute-forcing, port scanning, etc., and can correlate information to infer attack surfaces (e.g., automatically checking CVE when a specific Web framework version is found);
2. Vulnerability Detection and Analysis: Supports static/dynamic/hybrid detection modes, analyzes responses in real time to judge false positives, and evaluates vulnerability severity and exploitation difficulty;
3. Intelligent Payload Generation: Generates customized payloads based on the target environment, uses encoding obfuscation to bypass detection, and evaluates the impact scope to avoid accidental damage;
4. Secure Coding Assistance: Detects code security issues (SQL injection, XSS, etc.) in real time and provides repair suggestions, generates test cases to assist review, and promotes security left-shift.

RTPI is applicable to scenarios such as red team exercises (automated penetration), blue team defense (configuration audit/threat hunting), and security training (generating CTF problems/cases). Its practical value lies in accumulating expert experience into AI capabilities, enabling engineers with less experience to complete complex tasks, while senior experts can focus on high-value creative work.

Limitations: Large model hallucinations may lead to false positives and false negatives that require manual verification; automated detection of complex business logic vulnerabilities is difficult; AI-generated payloads need to be used carefully to avoid violations.

Future Directions: Introduce multimodal processing for captchas/documents; strengthen integration with mainstream security tools; explore reinforcement learning to allow agents to optimize strategies from practical feedback.

RTPI is a cutting-edge exploration of AI in the cybersecurity domain. Through Qwen fine-tuning and agentic architecture, it transforms large language model capabilities into practical security tools. As technology evolves, such intelligent platforms will play a more important role in offensive and defensive confrontations, promoting the industry toward automation and intelligence.
