PoCSmith - AI-Powered Proof-of-Concept Generator

Fine-tuned CodeLlama-7B model for generating security exploits and shellcode for defensive security research.

Model Description

PoCSmith is a LoRA-adapted CodeLlama-7B model trained on 1,472 CVE-exploit pairs and shellcode examples. It generates proof-of-concept exploits and multi-platform shellcode for authorized security testing.

Author: Regaan
GitHub: noobforanonymous/PoCSmith

Training Details

• Base Model: CodeLlama-7B
• Method: QLoRA 4-bit quantization
• Dataset: 1,472 samples (CVE-Exploit pairs + shellcode)
• Training Time: 3h 17min on RTX 4050 (6GB VRAM)
• Final Loss: 0.84 (30% reduction)
• Token Accuracy: 78.4%

Training Configuration

- LoRA Rank: 64
- LoRA Alpha: 16
- Learning Rate: 2e-4
- Epochs: 3
- Quantization: 4-bit (nf4)
- Batch Size: 1 (gradient accumulation x4)

Usage

Installation

pip install torch transformers peft bitsandbytes accelerate

Loading the Model

from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel
import torch

# Load base model with 4-bit quantization
base_model = AutoModelForCausalLM.from_pretrained(
    "codellama/CodeLlama-7b-hf",
    load_in_4bit=True,
    device_map="auto"
)

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained("codellama/CodeLlama-7b-hf")

# Load LoRA adapters
model = PeftModel.from_pretrained(base_model, "regaan/pocsmith")

# Generate
prompt = "Generate a reverse shell for Linux x64"
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0]))

Using the Full Framework

For a complete CLI tool with CVE parsing and shellcode generation:

git clone https://github.com/noobforanonymous/PoCSmith.git
cd PoCSmith
pip install -e .

# Generate exploit from CVE
python src/cli/main.py cve CVE-2024-1234

# Generate shellcode
python src/cli/main.py shellcode --platform linux_x64 --type reverse_shell

Capabilities

• CVE-based Exploit Generation: Generate PoCs from CVE descriptions
• Multi-platform Shellcode: x86, x64, ARM support
• Multiple Payload Types: Reverse shells, bind shells, exec
• Clean Output: Properly formatted code with comments

Limitations

• Requires 6GB+ VRAM for inference
• May generate non-working code for complex vulnerabilities
• Should not be solely relied upon for production exploits
• Requires manual review and testing

Ethical Use

This model is designed exclusively for:

• Authorized penetration testing
• Security research
• Educational purposes
• CTF competitions

NOT for:

• Unauthorized system access
• Malicious attacks
• Illegal activities

By using this model, you agree to:

1. Only test systems you own or have written permission to test
2. Follow responsible disclosure practices
3. Comply with all applicable laws
