Mythos Engine: Specialized Cybersecurity LLM

Mythos Engine is a highly specialized 1.5 billion parameter language model, fine-tuned by expper from the Qwen 2.5 Coder 1.5B Instruct base. Its core purpose is to assist in cybersecurity research, vulnerability analysis, and exploit development. The model leverages Chain-of-Thought reasoning with self-correction loops and mathematical logic notation to produce accurate, production-ready security code.

Key Capabilities

• Vulnerability Analysis: Explaining CVEs and understanding exploit mechanics.
• Exploit Development: Generating advanced Python exploits, analyzing PHP internals, MyBB exploitation, deserialization chains, and type juggling.
• Security Code Generation: Producing production-ready security code with high reasoning.
• Educational Tool: Ideal for red team education, blue team defense understanding, and CTF training.

Training Details

The model was fine-tuned using QLoRA (4-bit quantization) with Unsloth on a curated dataset of over 1000 examples. This dataset includes:

• 40% PHP Vulnerabilities: Type juggling, deserialization, filter chains.
• 25% MyBB Exploits: Admin CP RCE, SQL injection, XSS.
• 20% Python Exploit Development: C2 frameworks, scanners, injection techniques.

Important Note

This model is strictly for educational and authorized security testing only. It should not be used for unauthorized access or malicious activities.
