Social Engineering Specialist — Gemma 4 E4B (GGUF)

smd20/socialengineering is a domain-specialized conversational model for social engineering, phishing awareness, and red-team education, fine-tuned from Google Gemma 4 E4B using Unsloth and exported as BF16 GGUF for efficient local deployment with llama.cpp, Ollama, LM Studio, and related runtimes.

The model was trained on a large bilingual Q&A corpus derived from authoritative social-engineering reference books, covering definitions, attack techniques (phishing, vishing, pretexting, baiting, tailgating), case studies, and defensive strategies.

Model Summary

Intended Use

Primary use cases

• Organizational security-awareness chatbots
• Phishing and social-engineering education for analysts and end users
• Red-team / blue-team training scenarios in controlled environments
• Local, privacy-preserving Q&A over social-engineering concepts

Out-of-scope / misuse

This model is not a substitute for legal, operational, or incident-response authority. It must not be used to conduct unauthorized attacks, harvest credentials, or deceive individuals outside approved training and research contexts.

Training Procedure

Fine-tuning was performed in Unsloth Studio on top of gemma-4-E4B, using a bilingual social-engineering Q&A corpus built from structured knowledge articles extracted from eight reference books.

Training hyperparameters

Export configuration

The published checkpoint preserves the merged fine-tuned weights in GGUF form for deployment with llama.cpp-compatible runtimes.

Training Data

The model was trained on conversational Q&A pairs grounded in curated social-engineering knowledge. The underlying datasets are publicly released on Hugging Face:

Reference corpora

Knowledge articles were derived from the following legally acquired books:

• Deep Insight into Social Engineering
• ESET Social Engineering Handbook
• Learn Social Engineering: Learn the Art of Human Hacking (Erdal Ozkaya)
• Social Engineering: How Crowdmasters, Phreaks, Hackers (Gehl & Lawson)
• Social Engineering in Cybersecurity: Threats and Defenses (Gururaj et al.)
• Social Engineering: The Science of Human Hacking (Christopher Hadnagy)
• Social Engineering: The Art of Human Hacking (Christopher Hadnagy)
• Sefreta: Zero to Hundred Social Engineering (Persian)

Corpus construction pipeline

1. Controlled segmentation of reference books
2. Schema-driven knowledge article generation (JSONL)
3. Grounded bilingual Q&A generation with strict source constraints
4. Global deduplication and bilingual split

Evaluation & Limitations

• The model inherits base-model limitations and may hallucinate on out-of-domain queries.
• Training data were LLM-assisted and should be complemented with human review for high-stakes deployments.
• Copyright of source books remains with publishers; released datasets contain derived annotations only.
• BF16 GGUF requires approximately 15.1 GB VRAM/RAM for full-precision loading.
